Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flow chart of steps of an embodiment of a method for imaging a medical image according to the present invention is shown, which may specifically include the following steps:

step 101, obtaining current physical sign information of a patient.

And 102, determining the shooting position of the imaging equipment according to the current sign information and the preset sign information of the patient.

And 103, adjusting the imaging device to the shooting position to acquire the medical image.

In the embodiment of the present invention, the preset physical sign information refers to body shape feature information of the patient, which is acquired in advance and stored in an information base before medical imaging is performed. When medical imaging is performed, preset sign information of the patient can be screened from an information base, and then current sign information of the patient is obtained; of course, the current physical sign information of the patient may also be obtained first, and then the preset physical sign information of the patient is screened out from the information base, which is not limited in the embodiment of the present invention.

When medical imaging is performed, when a patient reaches an imaging area of the imaging device, the patient can be determined to be in position, and current physical sign information of the patient can be acquired after the patient is in position, wherein the current physical sign information refers to body shape feature information, position information and the like of the patient in the current state when the medical imaging is performed; for example, the current sign information may be a whole-body image of the patient, or may be a local image of a certain body part of the patient, or may be a two-dimensional image or a three-dimensional image of the patient, or may be other types of information. The types of the acquired medical images are different, and the current physical sign information to be acquired may also be different, and the current physical sign information to be acquired may be determined by referring to an actual situation specifically, which is not limited in this embodiment of the present invention.

In the embodiment of the invention, in order to make the acquired medical image clearer, the position of the medical equipment or the patient is often required to be adjusted before the medical image is acquired, at present, the medical equipment is often required to be adjusted by medical staff according to actual conditions before the medical image is acquired, and even the medical staff may be required to guide the patient to adjust the position on the spot, so that the acquisition process of the medical image is complicated, the acquisition efficiency is low, and automation cannot be realized. Therefore, in view of the above defects in the prior art, the embodiment of the present invention may automatically determine the shooting position of the imaging device according to the preset sign information and the current sign information of the patient, and then automatically adjust the imaging device to the shooting position to complete the full-automatic medical image acquisition process.

In the embodiment of the present invention, the position of the body part of the patient to be subjected to medical imaging in the current physical sign information may be determined according to the preset physical sign information and the current physical sign information of the patient (for example, when the lumbar vertebra of the patient is subjected to medical imaging, the position of the lumbar vertebra of the patient in the three-dimensional image may be determined), and then the shooting position of the imaging device may be automatically determined according to the position of the body part of the patient to be subjected to medical imaging in the current physical sign information. After the shooting position of the imaging device is determined, the imaging device can be automatically adjusted to the shooting position according to the set motion track, and the medical image of the patient can be automatically acquired, so that the full-automatic acquisition of the medical image is realized.

In the embodiment of the invention, the current physical sign information of the patient can be obtained firstly; then, determining the shooting position of the imaging equipment according to the current sign information and the preset sign information of the patient; then adjusting the imaging device to the shooting position for medical image acquisition; the method can automatically determine the shooting position according to the current sign information and the preset sign information, so that the imaging device can be automatically adjusted to the shooting position and medical images can be obtained, and further, the full-automatic obtaining of the medical images can be realized. The method is a full-automatic process, so that the medical image acquisition process is simple and the acquisition efficiency is high.

Referring to fig. 2, a flowchart illustrating steps of an alternative embodiment of a method for imaging a medical image is shown in an embodiment of the present invention, which may specifically include the following steps:

in the embodiment of the present invention, the fully automatic acquisition process of the medical image may be implemented with reference to steps 201 and 206.

Step 201, retrieving patient information for the patient from an information base.

Step 202, determining the preset physical sign information according to the patient information.

In the embodiment of the invention, before medical imaging, patient information can be obtained in advance and stored in an information base, wherein the information base can comprise the patient information of one or more patients; the patient information may include age, sex, and body shape feature information of the patient, and may also include other information of the patient, which is not limited in this embodiment of the present invention. When medical imaging is performed, the patient information for the patient can be called from the information base, then the preset sign information of the patient is screened from the patient information of the patient, and then the shooting position of the imaging device is determined. The preset physical sign information may include body shape feature information of the patient acquired in advance.

In an example of the present invention, during a medical X-ray imaging process, the terminal of the X-ray photographing system may retrieve patient information of a patient currently undergoing an X-ray examination from an information base of a hospital, and then screen preset physical sign information of the patient from the patient information.

Step 203, obtaining the current physical sign information of the patient.

In one example of the present invention, an imaging area of the imaging device may be predetermined and identified so that a patient can enter the imaging area according to the guidance of the position identification, for example, a rectangular frame may be used to identify the position of the imaging area. Whether the patient reaches the imaging area can be detected in real time, and when the patient enters the imaging area according to the position identification, the current physical sign information of the patient can be acquired, for example, the current physical sign information of the patient can be acquired by adopting a camera device. The current sign information may include body shape feature information of the patient in the current state and position information of the imaging region, for example, the current sign information may be a whole-body image of the patient in the imaging region.

In the embodiment of the present invention, after obtaining the current physical sign information of the patient, the shooting position of the imaging device may be determined according to the current physical sign information and the preset physical sign information of the patient, and specifically, refer to step 204 and step 205.

And step 204, determining a target shooting area of the patient according to the current sign information and preset sign information of the patient.

In the prior art, since the exact position of the target shooting area of the patient cannot be predicted, such as: when the lumbar vertebrae are shot, the proportion of the lumbar vertebrae of different patients to the height of the patients according to the body characteristics of the patients is different, and if the position distribution of the lumbar vertebrae is calculated according to the height of the patients, the position of the lumbar vertebrae cannot be accurately positioned, and then the shooting position of the imaging device cannot be accurately determined. In order to avoid the above defect, in the embodiment of the present invention, a target shooting area of the patient may be identified by combining the current sign information and the preset sign information of the patient, and then a shooting position of the imaging device may be calculated according to the target shooting area. Wherein, the substeps 41-43 can be referred to determine the target shooting area of the patient according to the current sign information and the preset sign information of the patient:

substep 41, determining an anatomical region of said patient according to said current vital sign information;

substep 42, determining a region to be shot of the patient according to the preset sign information;

substep 43 determining the target capturing region from the anatomical region and the region to be captured.

In the embodiment of the invention, the region to be shot of the patient can be identified from the preset sign information of the patient, the anatomical region of the patient can be identified from the current sign information of the patient, and then the target shooting region of the patient can be identified by combining the anatomical region and the region to be shot. Wherein the region to be photographed may be a body part of the patient to be medically imaged, for example, a lumbar vertebra of the patient. The target photographing region may be a region of the region to be photographed of the patient in the current vital sign information, for example, a region of the lumbar vertebra of the patient in the whole-body image. Wherein the anatomical region may be a region of the human anatomical part of the patient in the current vital sign information, for example, referring to fig. 5, a region of the head, chest, arms, waist, hip, thigh, hand, elbow, etc. of the patient in the whole-body image.

In an embodiment of the present invention, a preset recognition algorithm may be adopted to determine the anatomical region of the patient according to the current sign information. For example, a depth recognition algorithm of R-CNN (Region-based Convolutional Neural Networks) may be used to determine the anatomical Region of the patient in the whole-body image, and specifically, the following process may be referred to.

In an example of the present invention, after acquiring a whole-body image of the patient in an imaging region, referring to fig. 3, the whole-body image (input image) may be input first, and an image region of interest may be extracted from the whole-body image, then, the ConvNet (Convolutional Neural network) may be used to perform a process such as region classification on each of the extracted image regions (e.g., based on SVMs (Support vector machines), and then, the image regions with region classification may be subjected to a Bbox-Bounding regression process, such as a linear regression process with boundary box offset, so as to obtain an anatomical region of the patient (see fig. 5). The depth recognition algorithm of the R-CNN may adopt an AlexNet neural network model, and referring to fig. 4, the AlexNet neural network model may perform an analysis processing process of a five-layer convolutional layer and a three-layer fully connected layer (fullonconnected layer) on an image. Wherein, the AlexNet neural network model can be adopted to analyze and process the target shooting area in the whole-body image: first, an image of a fixed size of 227x227x3 may be input to the first layer, thereby generating 4096 analysis-processed data in the fully-connected layer of the seventh layer, and then 4096 data of the seventh layer may be input to the eighth layer to be processed, and a processing result (e.g., "Jia-Bin") may be output. Of course, other identification algorithms may be adopted to obtain the anatomical region of the patient according to the embodiment of the present invention, which is not limited in this respect.

The specific steps of determining the target shooting area according to the anatomical area and the area to be shot are as follows:

matching out the same area as the area to be shot from the anatomical area, and setting the area as the target shooting area.

In an example of the present invention, when it is determined that the region to be photographed of the patient is an arm, the arm may be matched with an anatomical region of the patient, such as a head, a chest, an arm, a waist, a hip, a thigh, a hand, and an elbow, so as to find the arm region from the anatomical region, and the arm region is set as the target photographing region, so that a medical image of the target photographing region may be acquired.

Step 205, determining the shooting position of the imaging device according to the target shooting area.

In the embodiment of the present invention, the position may be a spatial coordinate; the shooting position may be: spatial coordinates of the imaging device when performing medical imaging. Wherein the shooting position of the imaging device can be determined from the target shooting region with reference to sub-steps 51-53:

in the embodiment of the invention, the space coordinates of the target shooting area can be obtained first, and then the shooting position of the imaging device can be calculated according to the space coordinates. Wherein the spatial coordinates of the target photographing region can be acquired with reference to substeps 51-52:

and a substep 51 of acquiring pixel coordinates of the target shooting area.

And a substep 52 of determining the spatial coordinates of the target shooting area according to the pixel coordinates.

And a substep 53 of determining a shooting position of the imaging device according to the spatial coordinates.

In an example of the present invention, after the whole-body image of the patient is obtained, the target shooting area may be found from the whole-body image of the patient, the pixel coordinates of the target shooting area are obtained, the spatial coordinates of the target shooting area are calculated according to the pixel coordinates, and the shooting position of the imaging device, that is, the spatial coordinates of the imaging device when the medical image is obtained, is further calculated. Wherein the pixel coordinates are the locations of the pixels in the image. To determine the coordinates of the pixels, the coordinate system of the image is first determined. Common coordinate systems include an image coordinate system, a camera coordinate system, a world coordinate system, and the like. Wherein the image coordinate system may be established, and the spatial coordinates of the target photographing region may be calculated with reference to the following procedure:

in the image coordinate system x-y, a coordinate system u-v (u represents the abscissa of the pixel, and v represents the ordinate of the pixel) may be established with the upper left corner of the image as the origin, wherein a principal point (principal point) of the target capturing region in the whole-body image may be defined as the origin of the image coordinate system, (u0, v0) represents the coordinates of the origin in the u-v coordinate system, and (u, v) may be set as the ideal pixel coordinates of the target capturing region in the whole-body image, correspondingly,

the pixel coordinates that can be obtained for the target photographing region in reality, (x, y) can be set to the ideal physical coordinates of the target photographing region,

physical coordinates that can be actually obtained for the target photographing regionTo obtain the following relationship:

wherein k is₁、k₂Is a distortion coefficient of

Wherein (u0, v0) and (u0, v0) can be obtained by image processing of the target shooting area according to the relational expression,

(u, v), (x, y) calculating the aboveAnd further obtaining the space coordinate of the target shooting area. Wherein (u0, v0) can be calculated when the internal parameters of the image pickup device are acquired, and the whole body image can be automatically extracted and sorted by the circle center

The back projection residual may be obtained by a cvproject function in an OpenCV (Open Source Computer Vision Library) to obtain (u, v), (x, y) and (u, v) may be obtained by u-u 0 α x + cy and v-v 0+ β y (where α, c, and β are parameters of the imaging device, specifically, transformation parameters of image coordinates to pixel coordinates), to determine (u0, v0),After (u, v), (x, y), may beThe following equation is obtained:

the space coordinate of the target shooting area can be calculated according to the formula; and calculating the space coordinate of the imaging device when acquiring the medical image, namely the shooting position of the imaging device according to the space coordinate of the target shooting area.

And step 206, adjusting the imaging device to the shooting position to acquire the medical image.

In an example of the present invention, after determining the shooting position of the imaging device, a motion trajectory of the imaging device, such as a motion trajectory of a flat panel detector and a light pipe in the X-ray machine, may be obtained, and then the imaging device may be adjusted to the shooting position according to the motion trajectory, so as to obtain a medical X-ray image.

In the embodiment of the invention, the patient information aiming at the patient can be firstly called from an information base, and the preset physical sign information is determined according to the patient information; then obtaining the current physical sign information of the patient; determining a target shooting area of the patient according to the current sign information and preset sign information of the patient; determining the shooting position of the imaging equipment according to the target shooting area; then adjusting the imaging device to the shooting position for medical image acquisition; according to the method, the target shooting area of the patient can be automatically determined by combining the current sign information and the preset sign information of the patient, so that the shooting position of the imaging equipment can be accurately determined, the imaging equipment can be accurately adjusted to the shooting position, and a clear medical image can be acquired.
