The present embodiment provides an X-ray photographing system, and more particularly, to a digital flat panel X-ray photographing system, which can rapidly reproduce an X-ray image by using X-rays which penetrate through a human body and are collected by an X-ray detector (i.e., a flat panel detector) and processed by a computer system.

Referring to fig. 1-3, the radiography system includes a standing X-ray receiving apparatus 100, a horizontal X-ray receiving apparatus 200, a machine head apparatus 300, and a control unit (not shown). In some embodiments, the radiography system may include a stand-type radiography system and a recumbent radiography system. The stand-type radiography system may include a stand-type X-ray receiving apparatus 100, a machine head apparatus 300 and a control unit (not shown), which are mainly used for realizing stand-position radiography, such as chest radiography. The system may include a horizontal X-ray receiving device 100, a machine head device 300 and a control unit (not shown), which is mainly used for implementing X-ray photography in a lying position, such as a bed-lying position. The following description will be made mainly of an X-ray imaging system capable of being in both a standing position and a lying position, and these configurations can be applied to a standing X-ray imaging system and a lying X-ray imaging system.

The stand-up X-ray receiving device 100 (e.g., a chest stand X-ray receiving device) includes a stand 110 and a first cassette 120. The first cassette 120 has a flat panel mounting position for mounting the first flat panel detector 410. The first cassette 120 is mounted on the column 110 so as to be movable in the vertical direction, and has a plurality of standing plate fixing positions distributed at different heights in the vertical direction on a movement trajectory of the first cassette 120, and the first cassette 120 can be fixed at the standing plate fixing positions.

For example, the first sheet box 120 is slidably disposed on the upright 110, and the first sheet box 120 or the upright 110 may be disposed with a plurality of latches, blocks or other fixing structures, so that when the first sheet box 120 is moved to a desired standing plate fixing position, the first sheet box can be fixed by the latches, blocks or other fixing structures. In other embodiments, it is also possible to secure the first cassette 120 in a standing plate securing position in a manner that increases damping. In addition, in the conventional X-ray imaging system, there are various methods for moving the first cassette 120 on the column 110 and fixing a certain position, and these methods are applied to the configuration shown in the present embodiment.

The horizontal X-ray receiving device 200 (an X-ray receiving device in a bed lying position) includes a bed body 210, a bed board 220 mounted on the bed body 210, and a second cassette 230, wherein the second cassette 230 has a flat plate mounting position for mounting a second flat plate detector 420. The first flat panel detector 410 and the second flat panel detector 420 are different in the arrangement of the flat panel detectors, and may use the same or different flat panel detectors.

And the handpiece apparatus 300 includes a support 310 and a handpiece 320 mounted on the support 310, the handpiece 320 being capable of emitting X-rays to a corresponding first flat panel detector 410 and second flat panel detector 420. As shown in fig. 2 and 3, region a is indicated by the X-ray from handpiece 320.

The standing flat plate fixing position is correspondingly provided with a first in-place prompting structure (such as a first indicating mark 121) so as to prompt the first cassette 120 to move to the standing flat plate fixing position, and the distance between adjacent standing flat plate fixing positions is smaller than the height of the corresponding first flat plate detector 410, so that partial areas of adjacent images acquired by the first flat plate detector 410 are overlapped. The control unit receives the electric signals of the first flat panel detector 410 and the second flat panel detector 420 to form images, and uses the overlapping area in the adjacent images obtained by the first flat panel detector 410 to splice the adjacent images. The adjacent images refer to two images with continuity acquired by a flat panel detector (which may include the first flat panel detector 410 and the second flat panel detector 420, or one of them), that is, images obtained by continuously photographing the relevant part of the patient. For example, in one embodiment, the adjacent images acquired by the first flat panel detector 410 include images respectively acquired by the first flat panel detector 410 at adjacent standing flat panel holding positions.

The first in-place prompting structure can guide a user to accurately move the first sheet box 120 to the standing flat plate fixing position, and the distance between the adjacent standing flat plate fixing positions is smaller than the height of the corresponding first flat plate detector 410, so that adjacent images acquired by the first flat plate detector 410 in the first sheet box 120 are ensured to have splicing reference, namely, overlapping areas in the adjacent images, the control unit can splice the adjacent images by using the overlapping areas, and by analogy, a plurality of images are spliced into one image. Meanwhile, the size relationship between the distance between the adjacent fixed positions of the standing flat plates and the height of the first sheet box 120 is known, and based on the size relationship, which parts can be spliced together when the two images are spliced can be accurately known, so that the two images and the overlapped area can be mutually proved together, and more accurate spliced images can be obtained.

For example, referring to fig. 2, in an embodiment, the number of the standing-type flat plate fixing positions is 7, and the number of the corresponding first in-position prompting structures (such as the first indicator 121) is also 7. When images need to be spliced, the first cassette 120 can be moved from the 1 st standing flat plate fixing position to the 7 th standing flat plate fixing position in sequence, and an image is shot at each standing flat plate fixing position. In fig. 2, 120a is a schematic diagram of the first cassette 120 moving to the 4 th-standing flat panel fixing position, and 120b is a schematic diagram of the first cassette 120 moving to the 7 th-standing flat panel fixing position. Wherein, since the distance between the adjacent standing flat panel fixing positions is smaller than the height of the corresponding first flat panel detector 410, when the first cassette 120 is located at the 2 nd standing flat panel fixing position, the upper region of the collected image will overlap with the lower region of the collected image when the first cassette 120 is located at the 1 st standing flat panel fixing position. In this way, when the control unit stitches the two images, the overlapping region can be integrated as a stitch fusion region.

The embodiment provides the method for acquiring the images with the overlapped areas, can provide the accurate size relation, and can finish the image splicing according to the existing image splicing software. It is not necessary here to mention how the control unit specifically performs the stitching of the images.

In order to ensure the consistency of the size relation, in one embodiment, the distance between the adjacent standing flat plate fixing positions is the same.

To further improve the accuracy of the stitched image, in one embodiment, the spacing between adjacent standing flat panel holding positions is less than half the height of the corresponding first flat panel detector 410. In this way, the overlapping area in the adjacent images is larger, and the splicing of the images is more facilitated. In particular, in one embodiment, the spacing between adjacent standing plate holding positions may be 10-20cm, such as 15 cm.

Generally, the height of the effective imaging area of the first flat panel detector 410 is less than the overall height of the first flat panel detector 410, and therefore, preferably, in one embodiment, the distance between the adjacent standing flat panel fixing positions is less than the height of the corresponding first flat panel detector 410, so as to ensure that the adjacent images captured by the first flat panel detector 410 have an overlapping area.

Further, the first in-position prompting structure may be various ways capable of prompting the user that first cassette 120 has been moved to the standing plate holding position.

For example, referring to fig. 2, in one embodiment, the first in-place prompting structure includes a first indicator 121 disposed on the upright 110. The first cartridge 120 or the first flat panel detector 410 has the first alignment mark 130 matched with the first indicating mark 121. When the first alignment mark 130 is aligned with the first indication mark 121, the first cassette 120 is moved to the corresponding standing plate fixing position.

With this structure of the identification class, the shape thereof can be selected as desired. For example, in the present embodiment, the first indicator 121 is a triangle, and the corresponding first alignment mark 130 is also a triangle. When the two sharp corners are aligned, the first cassette 120 is moved to the corresponding standing plate fixing position. In addition, the first indicator 121 may also use color to increase the degree of recognition and improve the degree of attention.

In addition, in one embodiment, the first arrival prompting structure includes a first damping mechanism, and the first damping mechanism cooperates with the first sheet box 120 to increase the resistance when the first sheet box 120 moves to the corresponding standing flat fixing position. For example, the damping mechanism may, but is not limited to, provide resistance or a feel of being in place to the first pod 120 via an elastic member or friction pad (other damping mechanisms described below are equivalent).

Or, in another embodiment, the first arrival prompting structure includes a first detecting unit, the first detecting unit is triggered when the first film cassette 120 moves to the corresponding standing flat plate fixing position, the first detecting unit sends an arrival signal, and the control unit prompts or blocks the first film cassette 120 to move according to the arrival signal.

The above are merely examples of three different in-place hint structures, which may be implemented in other ways in other embodiments. The in-place prompting structures can be used alternatively or in any combination to improve the prompting effect. The same is true for the various in-position cue structures described below.

In addition, the handpiece 320 can emit X-rays to the corresponding first and second flat panel detectors 410 and 420. When the first flat panel detector 410 and even the second flat panel detector 420 have multiple positions, the handpiece 320 can rotate, translate or rotate and translate in combination to irradiate X-rays onto the corresponding first flat panel detector 410 and second flat panel detector 420.

Referring to fig. 2, in one embodiment, the head 320 is movably mounted on the support 310 in a vertical direction so as to transmit X-rays to the first flat panel detectors 410 at different heights in the standing X-ray receiving apparatus 100.

The moving track of the handpiece 320 in the vertical direction is provided with a plurality of handpiece vertical fixing positions arranged in the vertical direction, and the handpiece 320 can be fixed at the handpiece vertical fixing positions. For example, the handpiece 320 can be slidably disposed on the frame 310, and the frame 310 or the handpiece 320 can be provided with latches, detents, or other securing structures, which can be used to secure the handpiece 320 when it is moved to a desired vertical handpiece securing position. In other embodiments, it is also possible to secure handpiece 320 in a handpiece vertical fixation in a manner that increases damping. In addition, in the conventional X-ray imaging system, there are various methods for moving the head 320 on the support 310 and fixing a position, and these methods are all applied to the configuration shown in the present embodiment.

The vertical fixed position of aircraft nose 320 matches with the fixed position of standing flat board, makes aircraft nose 320 can the horizontally shine on the first flat board detector 410 that corresponds, and the vertical fixed position of aircraft nose corresponds and is equipped with the second suggestion structure that targets in place to suggestion aircraft nose 320 removes to the vertical fixed position of aircraft nose. In fig. 2, 320a is a schematic view of the handpiece 320 as it moves to the 5 th handpiece vertical holding position.

The head 320 horizontally irradiates the corresponding first flat panel detector 410, so that the deformation of the overlapping area on the adjacent images can be reduced, the control unit can more accurately and easily identify the overlapping area, and a better splicing effect can be obtained.

Of course, in some embodiments, the handpiece 320 may be configured to rotate to allow the X-rays it emits to illuminate the first flat panel detector 410 at all positions.

Similar to the first in-position notification feature, the second in-position notification feature can be a variety of ways that can notify the user that handpiece 320 has been moved to the handpiece vertical fixation position.

Referring to fig. 2, in one embodiment, the second position indicating structure includes a second indicating mark 330 disposed on the frame 310, the handpiece 320 has a second alignment mark 311 matching with the second indicating mark 330, and when the second alignment mark 311 is aligned with the second indicating mark 330, the handpiece 320 is moved to the corresponding handpiece vertical fixing position. Wherein the second indication mark 330 and the second alignment mark 311 are separately shown for clarity of illustration. In practical configurations, the second indicator 330 may be disposed on the frame 310 and the second alignment marker 311 may be disposed on the handpiece 320.

In addition, in one embodiment, the second arrival prompting structure includes a second damping mechanism, and the second damping mechanism is matched with the handpiece 320, so that resistance is increased or hand feeling is changed when the handpiece 320 moves to a vertical fixed position corresponding to the handpiece;

or, the second arrival prompting structure comprises a second detection unit, the second detection unit is triggered when the machine head 320 moves to the vertical fixed position corresponding to the machine head, the second detection unit sends an arrival signal, and the control unit prompts or prevents the machine head 320 from moving according to the arrival signal.

On the other hand, referring to fig. 2, in some embodiments, in order to perform both the standing-type photographing and the lying-type photographing, the head 320 is located above the bed plate 220, and the standing-type plate fixing position (shown as 120b in fig. 2) located at the lowest position is lower than the bed plate 220. Accordingly, the head 320 cannot move to the position of the first cassette 120 located below the bed 220. For this, in one embodiment, the head vertical fixing position at the lowest position is a rotation detection position (e.g., the position of the 5 th second indicator mark 330), the rotation detection position is higher than the table plate 220, the head 320 is rotatably mounted on the bracket 310, and when the head 320 is at the rotation detection position, the head 320 is rotated by an angle to send an X-ray to the first flat detector 410 located below the table plate 220.

As shown in fig. 2, the 5 th vertical fixing position (for example, the 5 th second indicator 330) is a rotation detecting position, and the first cassette 120 and the first flat panel detector 410 thereon located at the 6 th and 7 th standing flat panel fixing positions are irradiated by the handpiece 320 in a rotating manner when the 5 th vertical fixing position is located.

Referring to fig. 1, 4 and 5, in one embodiment, the head 320 rotates via a rotating shaft 330 disposed horizontally, and at least one rotation fixing position is disposed on a rotating track of the head 320, and the rotation fixing position matches with a standing flat plate fixing position located below the table plate 220, so that the head 320 can send X-rays to a first flat plate detector 410 located below the table plate 220. The rotating fixing position is correspondingly provided with a third in-place prompting structure (such as a third indicator 340) so as to prompt the handpiece 320 to rotate to the corresponding rotating fixing position.

Similar to the first in-position indicating structure, the third in-position indicating structure can be a variety of ways that can indicate to the user that the handpiece 320 has been rotated to the rotationally fixed position.

Referring to fig. 4 and 5, in an embodiment, the third position indicating structure includes a third indicator 340 disposed on the handpiece 320, the rotating shaft 330 or the bracket 310 has a third alignment mark 350 matching with the third indicator 340, and when the third alignment mark 350 is aligned with the third indicator 340, the handpiece 320 rotates to a corresponding rotation fixing position;

in another embodiment, the third arrival prompting structure comprises a third damping mechanism, and the third damping mechanism is matched with the handpiece 320, so that the resistance is increased or the hand feeling is changed when the handpiece 320 rotates to a corresponding rotation fixing position;

or, the third arrival prompting structure comprises a third detecting unit, the third detecting unit is triggered when the handpiece 320 rotates to the corresponding rotating fixed position, the third detecting unit sends an arrival signal, and the control unit prompts or prevents the handpiece 320 from rotating according to the arrival signal.

Generally, the horizontal X-ray receiving apparatus 200 is used for capturing images of some patients who cannot stand up, and is used in combination with the standing X-ray receiving apparatus 100. In order to enable the horizontal X-ray receiving device 200 to realize image stitching, referring to fig. 3, in an embodiment, the second cassette 230 is movably mounted on the bed 210 in a horizontal direction. The second sheet cassette 230 has a plurality of horizontal plate fixing positions on a moving track thereof, and the horizontal plate fixing positions are distributed at different positions in a horizontal direction. As shown in fig. 3, 230a is a schematic view of the second cassette 230 moving to the 4 th horizontal plate fixing position. The horizontal plate fixing position is correspondingly provided with a fourth in-place prompting structure (for example, a fourth indication mark 240) so as to prompt the second cassette 230 to move to the horizontal plate fixing position. The distance between the adjacent horizontal flat plate fixing positions is smaller than the length of the corresponding second flat plate detector 420, so that partial areas of the adjacent images acquired by the second flat plate detector 420 are overlapped. The length of the second flat panel detector 420 is substantially the same as the height of the first flat panel detector 410, and the first flat panel detector 410 and the second flat panel detector 420 are arranged in different ways, so in this embodiment, they are respectively illustrated for the sake of consistency with the drawings. Based on the same principle, the control unit uses the overlapping regions in the adjacent images obtained by the second flat panel detector 420 to stitch the adjacent images.

Similar to the first in-position prompting structure, the fourth in-position prompting structure may be various ways capable of prompting the user that the second cassette 230 has been moved to the horizontal plate fixing position.

For example, referring to fig. 3, in an embodiment, the fourth arrival prompting structure includes a fourth indication mark 240 disposed on the bed 210 or the bed plate 220, the second cassette 230 or the second flat panel detector 420 has a fourth alignment mark 231 matched with the fourth indication mark 240, and when the fourth alignment mark 231 is aligned with the fourth indication mark 240, the second cassette 230 moves to the corresponding horizontal flat panel fixing position;

in another embodiment, the fourth arrival prompting structure includes a fourth damping mechanism, and the fourth damping mechanism is matched with the second sheet box 230, so that the resistance is increased or the hand feeling is changed when the second sheet box 230 moves to the corresponding horizontal flat plate fixing position;

or, the fourth arrival prompting structure includes a fourth detecting unit, the fourth detecting unit is triggered when the second film box 230 moves to the corresponding horizontal flat plate fixing position, the fourth detecting unit sends an arrival signal, and the control unit prompts or blocks the second film box 230 to move according to the arrival signal.

In the horizontal X-ray receiving device 200, the bed plate 220 may be movable or fixed. For example. Referring to fig. 2 and 3, the bed plate 220 is mounted on the bed 210 in a manner capable of moving horizontally relative to the bed 210. Wherein the bed plate 220 shown in fig. 3 is located at the middle position of the bed 210, and the bed plate 220 shown in fig. 2 moves to the rightmost position relative to the bed 210.

In this manner, the bed plate 220 may be fixed, and more horizontal plate fixing positions than the bed plate 220 may be required to be provided for photographing the whole body part of the patient. When the bed plate 220 is mounted on the bed 210 in a manner of being capable of moving horizontally relative to the bed 210, the second flat panel detector 420 on one horizontal flat panel fixing position can photograph different parts of the patient, so that fewer horizontal flat panel fixing positions can be provided.

When the bed plate 220 is fixedly disposed, the adjacent images obtained by the second flat panel detector 420 include images respectively obtained by the second flat panel detector 420 at the adjacent horizontal flat panel fixing positions. When the bed plate 220 is horizontally movable, the adjacent images acquired by the second flat panel detector 420 are the images respectively acquired by the second flat panel detector 420 at the adjacent horizontal flat panel fixing positions and the images of different parts of the patient acquired by the second flat panel detector 420 at the same horizontal flat panel fixing position. For example, as shown in fig. 3, the second flat panel detector 420 located at the 1 st horizontal flat panel fixing position (the position indicated by the 1 st fourth indication mark 240) of the table 220 captures an image. The bed plate 220 is moved to the right to take the position shown in fig. 2, and the second flat panel detector 420 located at the 1 st horizontal flat panel fixing position (the position shown by the 1 st fourth indicator 240) captures another image. Assuming that the two images satisfy the requirement of continuity with an overlapping area, the two images belong to the adjacent images described in the present embodiment.

In the present embodiment, in the horizontal X-ray receiving apparatus 200, it is possible to acquire images having overlapping regions, and to provide an accurate dimensional relationship, and image stitching can be completed by existing image stitching software. It is not necessary here to mention how the control unit specifically performs the stitching of the images.

In order to ensure the consistency of the size relation, in one embodiment, the distance between the adjacent horizontal flat plate fixing positions is the same.

To further improve the accuracy of the stitched image, in one embodiment, the distance between adjacent horizontal flat panel fixing positions is less than half of the length of the corresponding second flat panel detector 420. In this way, the overlapping area in the adjacent images is larger, and the splicing of the images is more facilitated. Specifically, in one embodiment, the distance between adjacent horizontal plate holding positions may be 10-20cm, such as 15 cm.

Generally, the effective imaging area length of the second flat panel detector 420 is less than the overall length of the second flat panel detector 420, and therefore, preferably, in one embodiment, the distance between the adjacent horizontal flat panel fixing positions is less than the length of the corresponding second flat panel detector 420, so as to ensure that the adjacent images captured by the second flat panel detector 420 have overlapping areas.

In order to satisfy the purpose of enabling the handpiece 320 to vertically irradiate the second flat panel detector 420 at different positions in the horizontal direction, in one embodiment, the support 310 or the handpiece 320 is movably disposed in the horizontal direction.

The second flat panel detector 420 vertically irradiates the handpiece 320, so that the deformation of the overlapping area on the adjacent images can be reduced, the control unit can more accurately and easily identify the overlapping area, and a better splicing effect can be obtained. As shown in fig. 3, region a is X-ray emitted from handpiece 320.

Of course, in some embodiments, the handpiece 320 can be configured to rotate to allow the X-rays emitted by the handpiece to impinge on the second flat panel detector 420 at all positions.

The machine head 320 or the bracket 310 has a plurality of machine head horizontal fixing positions arranged along the horizontal direction on the moving track of the horizontal direction, the machine head 320 can be positioned at the machine head horizontal fixing positions, and each machine head horizontal fixing position is matched with one horizontal flat plate fixing position. As shown in fig. 3, region a is X-ray emitted from handpiece 320. The horizontal fixed position of the machine head is correspondingly provided with a fifth arrival prompting structure so as to prompt the machine head 320 to move to the horizontal fixed position of the machine head.

Similar to the first in-position prompting structure, the fifth in-position prompting structure can be various ways capable of prompting the user that the first handpiece 320 has been moved to the handpiece horizontal fixation position.

In one embodiment, the fifth arrival prompting structure includes a fifth indication mark, the handpiece 320 or the holder 310 has a fifth alignment mark matching with the fifth indication mark, and when the fifth alignment mark is aligned with the fifth indication mark, the handpiece 320 moves to the corresponding handpiece horizontal fixing position;

or the fifth arrival prompting structure comprises a fifth damping mechanism, and the fifth damping mechanism is matched with the handpiece 320 or the bracket 310, so that the resistance is increased or the hand feeling is changed when the handpiece 320 moves to the horizontal fixed position corresponding to the handpiece;

or, the fifth arrival prompting structure comprises a fifth detecting unit, the fifth detecting unit is triggered when the machine head 320 moves to the corresponding machine head horizontal fixing position, the fifth detecting unit sends an arrival signal, and the control unit prompts or prevents the machine head 320 or the bracket 310 from moving according to the arrival signal.

In addition, in one embodiment, the head 320 and the second sheet box 230 may also be configured as a horizontal linkage structure, that is, when the head 320 moves horizontally, the second sheet box 230 may be driven to move horizontally together, so that the convenience of controlling the head 320 and the second sheet box 230 is improved. Of course, when the head 320 needs to be moved in the vertical direction, the head 320 may be independently moved, and the second cartridge 230 does not affect the movement of the head 320. The linkage structure of the head 320 and the second cartridge 230 may be configured to be releasable, so that the linkage relationship of the head 320 and the second cartridge 230 may be released to drive any one of them to move independently.

The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
