When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a method of processing an image, which is applied to a medical device that obtains a medical image by performing scanning and exposure processing on a detection object, according to an exemplary embodiment, the method including:
in step S101, it is detected whether the scanning position of the medical device has changed.
The medical device has a function of scanning and exposing a detection object, and detects whether or not a scanning position of the medical device itself changes during use.
The scanning position of the medical device is a position in three-dimensional space. Detecting whether a change in the scanning position of the medical device has occurred may be: it is detected whether a position movement and/or rotation of the medical device has occurred. To enhance the function of the medical device, it is preferable to detect whether or not the medical device is moved in position and rotated.
Generally, the medical device includes a detection gantry that is movable relative to the detection object, including movement and rotation, and the medical device can detect whether a change in the scanning position of the medical device occurs by determining whether the detection gantry is moving.
The detecting rack is driven by a driving device in the medical equipment, and whether the detecting rack moves can be judged by judging whether the driving device is used for driving the detecting rack to move or not; the detection rack is provided with a positioning device, and whether the detection rack moves can be judged by judging whether the position information acquired by the positioning device changes or not; judging whether the detecting rack moves or not by using a sensor; and shooting the detection rack by using the camera, and judging whether the detection rack moves or not by analyzing the shot photo.
In step S102, when the scanning position of the medical device changes, a current exposure area contour corresponding to the current scanning position in a preset medical image is determined according to the current scanning position information of the medical device, where the preset medical image is an image obtained by scanning and exposing a detection object by the medical device at the preset scanning position.
The medical apparatus scans and exposes the detection object with rays (such as X-rays) to obtain a medical image. In the process that the medical equipment continuously performs scanning and exposure processing, the scanning position of the medical equipment can change, so that the exposure area of the detection object changes, and the exposure areas corresponding to different scanning positions are different.
The part of medical equipment comprises a rack, wherein a light emitter and a light detector are arranged on the rack, and in the process of continuously scanning and exposing the medical equipment, the rack moves and/or rotates in position, and the light emitter and the light detector on the rack also move and/or rotate in position, so that the exposure area of a detection object changes.
In this step, the preset medical image is an image obtained by the medical device at a preset scanning position, and the preset scanning position may be a scanning position when the medical device shoots a first medical image on the detection object after starting, or a scanning position when shooting a non-first medical image, and the like.
After detecting that the scanning position of the medical equipment has changed, the medical equipment acquires the current scanning position information of the current scanning position, and determines the contour of the current exposure area corresponding to the current scanning position in the preset medical image according to the current scanning position information.
In an alternative embodiment, fig. 2 is a flow chart illustrating another method of processing an image according to an exemplary embodiment, the present step 102 may be implemented by: in step S1021, a preset medical image is acquired; in step S1022, according to the current scanning position information of the medical device, a current exposure area contour corresponding to the current scanning position in the acquired preset medical image is determined.
For the above step S1021, there are various ways to acquire the preset medical image, for example, the first way: when the medical equipment is positioned at a preset scanning position, scanning and exposing the detection object to obtain a preset medical image; the second way is: and acquiring a preset medical image sent by an interaction device in communication with the medical device, wherein the interaction device can be a management device corresponding to the medical device, a cloud platform interacted with the medical device and the like.
For the step S1022, the medical device may determine, according to the current scanning position information of the medical device itself, a current exposure area profile corresponding to the current scanning position in the preset medical image.
Illustratively, fig. 3 is a schematic structural view of a medical apparatus according to an exemplary embodiment, and referring to fig. 3, the medical apparatus includes a light detector 1, a light emitter 2, and a test bed 3, wherein the light detector 1 and the light emitter 2 are disposed opposite to each other, the test bed 3 is disposed between the light detector 1 and the light emitter 2, and a test object a is disposed on the test bed 3.
In operation of the medical apparatus shown in fig. 3, the light emitter 2 emits X-rays, which are transmitted to the light detector 1 through the detection object a, and the region of the detection object a through which the X-rays pass is referred to as an exposure region b.
The detection center point A1 is the center point of the detection surface 11 of the light detector 1, the exposure center point B1 is the center point of the exposure area plane B of the exposure area, and the emission center point C1 is the center point of the emission surface 21 of the light emitter 2. In the three-dimensional space, the detection center point A1, the exposure center point B1, and the emission center point C1 are located on the same straight line, and the straight line is perpendicular to the detection surface 11 and the exposure area plane B1, respectively, that is, the detection surface 11 is parallel to the exposure area plane B1.
When the light detector 1 and the light emitter 2 are moved and/or rotated in synchronization, the exposure area on the detection object a is changed.
When this step S1022 is performed using the medical apparatus shown in fig. 3, referring to fig. 4, there is shown another flowchart of a method of processing an image according to an exemplary embodiment, and the step S1022 may be implemented by the following steps S1022-1 to S1022-6:
in step S1022-1, the first spatial coordinates of the detection center point A1, the second spatial coordinates of the exposure center point B1, and the third spatial coordinates of the emission center point C1 are acquired.
The first, second and third spatial coordinates are all three-dimensional coordinates.
A positioning device may be provided on the light detector 1, by means of which the first spatial coordinates of the detection center point A1 are acquired. A positioning device may be provided on the light emitter 2, by means of which the third spatial coordinates of the emission center point C1 are obtained.
Assume that the first spatial coordinate of the detection center point 111 is (x 1 ,y 1 ,z 1 ) The second spatial coordinate of the exposure center point B1 is (x 2 ,y 2 ,z 2 ) The third spatial coordinate of the emission center point C1 is (x 3 ,y 3 ,z 3 ) Under this assumption, the medical device is acquiring a first spatial coordinate (x 1 ,y 1 ,z 1 ) And a third space coordinate (x 3 ,y 3 ,z 3 ) After that, the second spatial coordinates (x) can be obtained by 2 ,y 2 ,z 2 ) The method comprises the following specific steps:
first, the Z-axis coordinate Z of the second spatial coordinate is determined based on the height of the test bed 3 and the thickness of the test object a 2 。
In operation, the bottom surface of the test bed 3 facing the light emitter 2 may be set to lie on a plane with zero Z-axis in the spatial coordinate system, in which case the Z-axis coordinate of the detection center point A1 may be calculated by: the Z-axis coordinate of the second space coordinate is obtained by adding half of the thickness of the test object a and the height of the test bed 3.
Assuming that the height of the test bed 3 is L1, the thickness of the test object a is L2, a secondZ-axis coordinate Z of space coordinates 2 Is (L2/2+L1).
Next, according to the first spatial coordinates (x 1 ,y 1 ,z 1 ) Third space coordinates (x 3 ,y 3 ,z 3 ) And detecting the Z-axis coordinate (L2/2+L1) of the center point A1, determining the X-axis coordinate X of the second spatial coordinate 2 And Y-axis coordinate Y 2 。
In operation, since the first spatial coordinates (x 1 ,y 1 ,z 1 ) And a third space coordinate (x 3 ,y 3 ,z 3 ) The straight line passing through the detection center point A1 and the emission center point C1 is determined, and thus the coordinates (X, y, z) of any point X on the straight line can be calculated by the following formula:
X(x,y,z)＝C1(x 3 ,y 3 ,z 3 )+f×(A1(x 1 ,y 1 ,z 1 )-C1(x 3 ,y 3 ,z 3 ))；
where f is a real number.
Due to the point A1 (x 1 ,y 1 ,z 1 ) And point C1 (x 3 ,y 3 ,z 3 ) It is known that the exposure center point B1 is located on the straight line, and the Z-axis coordinate Z of the exposure center point B1 2 Since (L2/2+L1), the Z-axis coordinate (L2/2+L1) of the exposure center point B1 is substituted into the above formula to obtain f.
Substituting f into the formula, and obtaining X-axis coordinate X of the exposure center point B1 through coordinate calculation 2 Y-axis coordinate Y of exposure center point B1 2 。
Through the above multi-step calculation, the second spatial coordinates (x 2 ,y 2 ,z 2 )。
In step S1022-2, a plane equation of the detection surface 11 is determined based on the first spatial coordinates and the third spatial coordinates.
Since the line connecting the detection center point A1 and the emission center point C1 is perpendicular to the detection surface 11 of the light detector 1 and the detection center point A1 is located on the detection surface 11, the plane equation of the detection surface 11 can be determined according to the first spatial coordinate of the detection center point A1 and the third spatial coordinate of the emission center point C1.
Illustratively, according to the first spatial coordinate (x 1 ,y 1 ,z 1 ) And a third space coordinate (x 3 ,y 3 ,z 3 ) Determining a normal vector n (a, b, c) of the detection surface 11, wherein a is equal to x 1 -x 3 B is equal to y 1 -y 3 C is equal to z 1 -z 3 The method comprises the steps of carrying out a first treatment on the surface of the Further, according to the normal vector n and the first space coordinate (x 1 ,y 1 ,z 1 ) Determining the plane equation of the detection surface 11: a (x-x) 1 )+b(y-y 1 )+c(z-z 1 )＝0
In step S1022-3, the detection surface profile 111 of the detection surface 11 is determined based on the plane equation and the relative positional information of the detection center point A1 and the sides of the detection surface 11.
The structure of the detection surface 11 is relatively fixed, in the method, the medical device presets the relative position information of the detection center point A1 of the detection surface 11 and each side of the detection surface 11, and when the medical device executes the step, the medical device acquires the preset relative position information, and determines the detection surface profile 111 of the detection surface 11 according to the relative position information and the plane equation of the detection surface 11 determined in step S1022-2.
In the medical device shown in fig. 3, the detection surface 11 is rectangular, and the detection surface may be circular or the like.
There are various kinds of suitable relative position information, and for example, when the detection surface 11 is rectangular, the relative position information may include: the distance between the detection center point A1 and each side of the detection surface 11 and the length of each side; when the detection surface 11 is circular, the relative position information may include: the distance of the detection center point A1 from the edge of the detection surface 11.
Specifically, a plane in which the detection surface 11 is located may be drawn in three-dimensional space according to a plane equation of the detection surface 11, where the detection center point A1 is a known point, and then each side of the detection surface 11 is drawn on the plane according to relative position information of the detection center point A1 and each side of the detection surface 11, so as to obtain the detection surface profile 111.
In step S1022-4, the detection surface profile 111 is reduced by using the detection center point A1 as the zoom center according to the ratio of the first distance between the emission center point C1 and the exposure center point B1 to the second distance between the emission center point C1 and the detection center point A1, to obtain the reduced detection surface profile 111.
In fig. 3, the exposure area plane B1 and the detection surface 11 are square, the detection surface 11 includes a detection center point A1 and a vertex point A2, the exposure area plane B1 includes an exposure center point B1 and a vertex point B2, and since Δc1b1b2_Δc1a1a2, the ratio of the line segment B1B2 to the line segment A1A2 can be determined according to the ratio of the first distance to the second distance, and then the ratio of the area of the exposure area to the area of the detection surface 11, that is, the reduction ratio of the detection surface profile 111 is determined.
After the reduction ratio of the detection surface contour 111 is determined, the detection surface contour 111 is reduced according to the determined reduction ratio with the detection center point A1 of the detection surface 11 as the zoom center.
In step S1022-5, the reduced detection surface profile 111 is translated in accordance with the direction toward the detection object a and a specified distance, which is the difference between the second distance and the first distance, to obtain the target profile.
After obtaining the reduced detection surface profile 111, the medical device needs to determine movement information of the reduced detection surface profile 111, and move the reduced detection surface profile 111 according to the movement information. The movement information may include information of a movement direction, a movement distance, and the like.
Referring to fig. 3, after obtaining the reduced detection surface profile 111, the medical apparatus uses the distance between the detection center point A1 and the exposure center point B1 as the movement distance of the reduced detection surface profile 111 and uses the direction toward the detection object a as the movement direction of the reduced detection surface profile 111.
Then, the reduced detection surface profile 111 is translated in a direction toward the detection object a and a specified distance, and a target profile is obtained.
In step S1022-6, the current exposure area profile is determined based on the target profile.

Based on the settings of steps S1022-61 and S1022-62, the corresponding display of the three-dimensional target contour in the two-dimensional preset medical image is realized.
In an alternative embodiment, the medical device may further perform the following operation when it is determined that the target profile has rotated relative to the preset exposure area profile: first, determining rotation information of the rotation; and secondly, outputting the rotation information according to a preset information output mode.

Compared with the related technical scheme, the method can effectively reduce the times of scanning and exposure treatment, thereby reducing the physical damage of rays used by medical equipment to doctors and patients.
When the rotation information includes: when the contour line and other information rotate towards the direction of the light emitter in the target contour, the operation of outputting the rotation information according to the preset information output mode can be realized by the following modes: and carrying out special marking on the outline of the part of the current exposure area obtained by projection of the outline in the preset medical image.

Compared with the related technical scheme, the method can effectively reduce the times of scanning and exposure treatment, thereby reducing the physical damage of rays used by medical equipment to doctors and patients.
For example, fig. 6 is a medical image taken by the medical apparatus shown in fig. 3, the medical image shown in fig. 6 including a black exposure area profile N1 and a white exposure area profile N2, the center points of the two profiles being coincident, the exposure center point of the white exposure area profile N2 being marked with a white cross.
The black exposure area outline N1 is an exposure area outline of a first medical image shot by the medical device on the patient, and it should be noted that the actual exposure area may be an entire image, the actual exposure area outline N1 may be an outline of the entire image, and in order to enhance the visualization of the black frame, the black frame may be appropriately reduced to highlight the frame structure; the white exposure field profile N2 is the exposure field profile of the second medical image that the medical device takes on the patient after the rotation has occurred.
An arc line is arranged at the junction of the exposure area outline N1 and the exposure area outline N2, the right side part of the exposure area outline N2 is a broken line, and according to the arrangement of the arc line and the broken line, the scanning angle of the medical equipment deflects, and the scanning angle deflects clockwise along the viewing direction from the foot to the head of a patient.
