Fig. 1 is a flowchart illustrating an image processing method according to an exemplary embodiment, applied to an image processing system, which may be an angiography system or the like, the method illustrated in fig. 1 including:

in step 101, a region marker set for a vessel lesion region presented by a detection image is acquired.

The detection image can display the vascular structure, and the vascular lesion area can be determined by identifying the vascular structure in the detection image. For example, the detection image may be a blood vessel subtraction image capable of displaying a blood vessel structure, and a blood vessel lesion region such as a blood vessel stenosis region may be determined by identifying the blood vessel structure in the blood vessel subtraction image.

In an alternative embodiment, the operation of acquiring a region marker set for a blood vessel lesion region presented in the detection image may include: firstly, in the process of displaying a detection image, detecting the dragging operation of a target mark frame selected from a preset mark frame set; secondly, in response to the end of the drag operation, determining a position (hereinafter referred to as a first position) of the target mark frame at the end of the drag operation; then, the target mark frame is marked at the first position in the detection image, and the area mark is obtained.

For example, a toolbar is displayed on an interface displaying the detection image, a plurality of mark frames are arranged in the toolbar, the physical sizes of marks of the mark frames are different, and/or the graphics of the mark frames are different, and the graphics of the mark frames may include at least one of the following: frame structure, frame color, frame transparency, etc. The doctor selects the target marking frame, drags the target marking frame to the blood vessel focus area in the detection image, and uses the marking frame to limit the blood vessel focus area.

In this embodiment, in the process of displaying the detection image, the doctor selects and drags the target mark frame, and the image processing system draws the target mark frame in the detection image according to the position of the target mark frame when the dragging operation is finished and the graph of the target mark frame.

In an alternative embodiment, after acquiring a detection image for a detection object, the image processing system may automatically identify a blood vessel lesion structure in the detection image, determine a blood vessel lesion region surrounding the blood vessel lesion structure, mark the blood vessel lesion region in the detection image, and obtain a region mark.

In this embodiment, the image processing system has a function of automatically determining a blood vessel lesion area in the detection image, and marking the blood vessel lesion area in the detection image to obtain a region mark, thereby omitting marking operations by a doctor and improving marking efficiency.

In an alternative embodiment, fig. 2 is a schematic structural diagram illustrating an image processing system according to an exemplary embodiment, and referring to fig. 2, the image processing system includes: the detector comprises a ray source 1, a flat panel detector 2 and a bed plate 3, wherein the bed plate 3 is positioned between the ray source 1 and the flat panel detector 2. In the process of detecting the detection object 4, the detection object 4 lies on the bed plate 3.

The operation of acquiring a region marker set for a vessel lesion region presented in a detection image may include: the method comprises the steps of firstly, obtaining a target mark frame selected from a preset mark frame set, wherein the mark frame in the mark frame set carries size information, and the size information indicates the size of an interventional device; a second step of determining a first distance from the ray source to a central line of the detection object and a second distance from the ray source to the flat panel detector; determining the projection size of the target size on the flat panel detector according to the first distance, the second distance and the target size, wherein the target size is the size of the interventional device indicated by the size information carried by the target marking frame; and a fourth step of drawing a mark frame having a projection size in the detection image to obtain a region mark.

For the first step, the image processing system is provided with a set of marker frames comprising at least one marker frame, each marker frame carrying dimension information indicating a dimension of the interventional device.

After determining the size of the interventional device to be used, the doctor finds out a marking frame (namely a target marking frame) with the size indicated by the carried size information and the size of the interventional device identical to the size of the interventional device by identifying the size indicated by the size information carried by the marking frame.

For the second step, in a case where the inspection object 4 is laid on the bed plate 3 and kept motionless, a first distance H from the radiation source 1 to the center line of the inspection object 4 is fixed, and a second distance H from the radiation source 1 to the flat panel detector 2 is fixed.

For the third step, a projection size x of the target size L on the flat panel detector 2 may be determined based on the principle of similar triangles and according to the first distance H, the second distance H and the target size L.

For the fourth step, the image processing system includes an image rendering module capable of rendering graphics according to the pixel size and the number of pixels of a single pixel.

The image processing system can divide the projection size x by the pixel size of a single pixel to obtain the number N of pixels after obtaining the projection size x, and send the number N of pixels to the image drawing module, so that the image drawing module draws a mark frame with the size of x in the detected image according to the number N of pixels and the pixel size of the single pixel, and the mark frame with the size of x is used as an area mark.

In an alternative embodiment, the detection image is a two-dimensional image, and the area markers in the detection image are two-dimensional area markers.

The image processing system may acquire an original detection image, which is a three-dimensional image, acquire a three-dimensional region marker for a three-dimensional blood vessel lesion region in the original detection image, and then project the original detection image marked with the three-dimensional region marker to obtain a two-dimensional detection image.

By adopting the method, the two-dimensional detection image marked with the two-dimensional area mark is obtained by projecting the three-dimensional original detection image marked with the three-dimensional area mark.

In step 102, a real-time contrast image acquired for the same examination object is acquired.

The image processing system has the function of acquiring real-time contrast images which do not display the vascular structure. The image processing system may acquire a test image of the test object first and then acquire a real-time contrast image of the test object.

During the process from the acquisition of the detection image to the acquisition of the real-time contrast image, it can be understood that the position of the detection object is not changed.

In step 103, a region marker is marked at a target position in the real-time contrast image, where the target position is a position of a vascular lesion in a vascular lesion region in the detection image.

In an alternative embodiment, the image size of the detection image is the same as the image size of the real-time contrast image.

The operation of marking a region marker at a target location in a real-time contrast image may include: step 1, replacing the pixel value of the pixel used for displaying the area mark in the detected image with a first numerical value, and replacing the pixel value of the pixel not used for displaying the area mark with a second numerical value to obtain a binary image; and 2, superposing the binary image and the real-time contrast image.

For step 1, the area mark may be a mark frame, and the pixel value of the pixel in the detected image used for displaying the area frame may be replaced by a first numerical value, and the pixel value of the pixel not used for displaying the mark frame may be replaced by a second numerical value, so as to obtain a binary image.

The first value may be 1 and the second value may be 0. The first and second values may be sized as desired.

For step 2, the binary image and the real-time contrast image may be superimposed according to the pixel value of the pixel for displaying the region marker in the detection image and the transparency of the region marker.

For example, the binary image is denoted as M, the real-time contrast image is denoted as I, and the binary image M and the real-time contrast image I may be superimposed by using the following formula:

I_m＝I×(1-k)+M×k×scale

wherein, I_mThe image after M and I are superposed; k is the transparency of the area mark, when k is more than or equal to 0 and less than or equal to 1 and k is equal to 1, the area mark is completely opaque,when k is 0, the area mark is completely transparent; scale is a pixel value of a pixel for displaying an area marker in a detection image, and the area marker is displayed brighter the larger the Scale.

M and I are the same size, and superimposing M and I is understood to mean: the pixel values of the same pixel location in M and I are superimposed.

For a color display, pixels in an image comprise an R (red) sub-pixel, a G (green) sub-pixel and a B (blue) sub-pixel, and when a binary image M and a real-time contrast image I are superimposed, it is necessary to superimpose pixel values of the R sub-pixels at the same pixel position, superimpose pixel values of the G sub-pixels at the same pixel position, superimpose pixel values of the B sub-pixels at the same pixel position, and obtain a superimposed image of M and I from three superimposed results.

The formula of superimposing the pixel values of the three sub-pixels is as follows:

I_mR＝I_R×(1-k)+M×k×scale_R

I_mG＝I_G×(1-k)+M×k×scale_G

I_mB＝I_B×(1-k)+M×k×scale_B

wherein, I_RIs the pixel value of the R sub-pixel in I, Scale_RTo detect the pixel value of the R sub-pixels in the image for the display area markers, I_mRThe pixel value of the R sub-pixel after superposition;

I_Gis the pixel value of the G sub-pixel in I, Scale_GTo detect the pixel value of the G sub-pixel in the image for the display area mark, I_mGThe pixel value of the G sub-pixel after superposition;

I_Bis the pixel value of the B sub-pixel in I, Scale_BTo detect the pixel value of the B sub-pixel in the image for the display area mark, I_mBIs the pixel value of the superposed B sub-pixel.

In an alternative embodiment, the operation of marking a region marker at a target location in a real-time contrast image may include: firstly, determining the position information of a region mark in a detection image; second, a region marker is marked at a target location having the location information in the real-time contrast image.

The size of the detection image is the same as that of the real-time contrast image, and when the position of the detection object does not move, the position of the vascular lesion structure in the detection object relative to the image does not change.

In this embodiment, the region markers having the same position are drawn in the real-time contrast image according to the position information of the region markers in the detection image.

In an alternative embodiment, the relative position relationship between the region marker in the detection image and the specified structure may be determined after acquiring the region marker set for the blood vessel lesion region presented in the detection image, the position of the specified structure in the real-time contrast image may be determined after acquiring the real-time contrast image, and the position of the region marker to be marked (i.e., the target position) in the real-time contrast image may be determined according to the position of the specified structure and the relative position relationship.

For example, when the patient breathes, the diaphragm moves and drives some blood vessels of the abdomen to move, the relative position relationship between the area markers in the detection image and the diaphragm can be determined, and finally the diaphragm in the real-time contrast image drives the area markers to move.

Under the ideal condition, the detection object does not move in the process of acquiring the detection image to the real-time contrast image, however, in the actual process, the detection object often moves, so that the position of the vascular lesion structure inside the detection object changes. By adopting the method provided by the embodiment, the region mark in the real-time contrast image can synchronously move along with the specified structure, and the region mark can accurately mark the blood vessel focus region.

In step 104, the real-time contrast image marked with the region marker is output.

The image processing system includes a display on which a real-time angiographic image marked with a region marker may be displayed.

In an alternative embodiment, the region markers in the real-time contrast image may be marker boxes. During the interventional operation, a doctor uses a delivery device to deliver an interventional device (such as a vascular stent) into a blood vessel, and determines to deliver the interventional device to a vascular lesion when a real-time contrast image shows that the interventional device enters a marking frame.

The image processing system can determine whether the size of the intervention device in the real-time contrast image is larger than that of the marking frame, if so, prompt information is output to prompt a doctor that the size of the intervention device selected by the doctor is too large, and the intervention device with a small size is recommended to be replaced.

In this embodiment, the image processing system has a function of determining whether the size of the intervention device in the real-time contrast image is larger than the size of the marker frame, and if so, outputting prompt information, so that a doctor can know that the size of the intervention device is not appropriate, and can replace the intervention device with the appropriate size in time, thereby ensuring smooth operation of the intervention operation.

In the embodiment of the disclosure, a region mark set for a blood vessel focus region presented by a detection image is acquired, a real-time radiography image acquired for the same detection object is acquired, the region mark is displayed at a target position in the real-time radiography image, the target position is a position of a focus displayed in a blood vessel focus region, and the real-time radiography image marked with the region mark is output, so that the region mark of the blood vessel focus region is displayed in the real-time radiography image, a doctor can conveniently determine that the blood vessel focus exists in the region marked by the region mark by looking up the region mark in the real-time radiography image, an interventional device is accurately conveyed to the blood vessel focus, and smooth operation of an interventional operation is ensured.
