Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to a medical image editing method, apparatus, computer device, and readable storage medium.
Background
In the current medical diagnosis process, most focus areas can be calculated by a common auxiliary diagnosis algorithm, but due to the performance limitation of the algorithm, the focus areas may deviate from the actual focus areas, so that doctors are required to edit focus areas with errors, and focus area results with higher accuracy are finally obtained. For example, for detecting a focal region of cerebral hemorrhage, if the range of the focal region calculated by the auxiliary diagnostic algorithm is larger, a doctor is required to erase the redundant region; if the range is small, a doctor is required to fill in the area which is not detected. In the process of editing a focal region of a medical image, it is generally necessary to adjust the size of an editing tool (such as a filling pen), for example, the filling of a larger focal region can be quickly performed by using the filling pen with a larger size; the use of smaller size pens for filling smaller lesion areas reduces filling errors.
When the size of the editing tool is adjusted in the traditional technology, the adjusted size of the editing tool is required to be selected in the tool area, or the adjusted size of the editing tool is required to be input in a text box of the tool area, or a scroll bar corresponding to the size of the editing tool in the tool area is dragged, and then the editing area is returned to carry out editing; if the adjusted editing tool size does not meet the requirement, the tool area needs to be returned again to adjust the editing tool size.

The application discloses a medical image editing method, a medical image editing device, computer equipment and a readable storage medium, and aims to solve the technical problems.
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application are further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
It should be noted that, the execution subject of the method embodiments described below may be a medical image editing apparatus, and the apparatus may be implemented as part or all of a computer device by software, hardware, or a combination of software and hardware. The following method embodiments are described taking an execution subject as an example of a computer device, where the computer device may be a terminal, may be a separate computing device, or may be integrated on a medical imaging device, and this embodiment is not limited to this.
Fig. 1 is a flow chart of a medical image editing method according to an embodiment. The embodiment relates to a specific process that the computer device adjusts the action range of the current editing tool according to the acquired action range adjustment instruction. As shown in fig. 1, the method includes:
s101, acquiring an action range adjustment instruction input in an editing area of a medical image; the action range adjustment instruction characterizes an action range adjustment amount corresponding to the current editing tool.
Specifically, in the process of editing the medical image, if the focal area in the medical image is filled, when the action range of the currently used editing tool needs to be adjusted, the action range adjusting instruction can be input in the current editing area, and then the computer equipment can acquire the action range adjusting instruction in real time. The action range adjustment instruction in the embodiment is input in the editing area of the medical image, and the selection is not needed to be repeated in the tool area, and optionally, the user can input the action range adjustment instruction through a mouse, a keyboard shortcut key or other input devices connected with the computer device; when the display screen of the computer device is a touch screen, the user can also directly input an action range adjustment instruction on the touch screen for the editing tool.
The action range adjustment instruction characterizes an action range adjustment amount of the current editing tool, and optionally, at an initial time, the action range of the editing tool may be a default value of the system. For example, when the application range adjustment command is input through a keyboard shortcut key (such as Ctrl key) and a mouse wheel, the action range of the character editing tool is doubled by sliding the wheel down one circle, and the action range of the character editing tool is doubled by sliding the wheel up one circle.
S102, in the editing area, adjusting the action range displayed by the current editing tool according to the action range adjustment instruction, and editing the medical image according to the editing instruction.
Specifically, after the computer device obtains the action range adjustment instruction, the instruction may be parsed to obtain an action range adjustment amount corresponding to the instruction, and then the action range of the current editing tool is adjusted for the action range adjustment amount in the editing area, and displayed to the user in real time. If the adjusted action range of the editing tool does not meet the requirement, the user can input the action range adjustment instruction again in the editing area. For example, if the action range adjustment amount is one time the action range of the editing tool, the computer device adjusts the action range of the editing tool to be two times the original action range and displays it. The computer device can then receive editing instructions input by the user through the adjusted editing tool to edit the medical image.
Alternatively, the display form of the current editing tool on the editing area may be a circle, and the radius of the circle represents the action range of the current editing tool, for example, assuming that the radius of the circle is 5mm, the action range of the current editing tool is a circle with a radius of 5 mm. Optionally, the display form of the current editing tool may be a rectangle, and the side length (length and width) of the rectangle represents the action range of the current editing tool; of course, the display form of the editing tool may be other shapes, and the present embodiment is not limited to this.
According to the medical image editing method provided by the embodiment, the computer equipment firstly acquires an action range adjustment instruction input in an editing area of a medical image, wherein the action range adjustment instruction represents an action range adjustment amount corresponding to a current editing tool; and then adjusting the action range displayed by the current editing tool in the editing area according to the action range adjustment instruction, and editing the medical image according to the editing instruction. In the method, the action range adjustment instruction is input through the editing area of the medical image, and the tool area and the editing area do not need to be switched back and forth, so that the operation steps are simplified, and the editing efficiency of the medical image is improved; and the action range of the adjusted editing tool is displayed in the editing area in real time, so that a user can quickly know the action range of the adjusted editing tool, and the interactivity of the medical image editing process is improved.
Fig. 2 is a flowchart of a medical image editing method according to another embodiment. The embodiment relates to a specific process that the computer device adjusts the action range displayed by the current editing tool according to the action range adjustment instruction. Optionally, on the basis of the foregoing embodiment, as shown in fig. 2, S102 includes:
s201, acquiring the current action range of the current editing tool.
Specifically, the computer device first obtains the current scope of action of the current editing tool, such as the radius of the circular editing tool, the side length of the rectangular editing tool, and the like.
S202, analyzing the action range adjustment instruction, and determining the action range adjustment amount corresponding to the action range adjustment instruction.
Specifically, since the action range adjustment instruction characterizes the action range adjustment amount of the current editing tool, the computer device can obtain the corresponding action range adjustment amount thereof by analyzing the action range adjustment instruction.
Optionally, the computer device analyzes the action range adjustment instruction, so that a position change amount of the input control in a preset direction of the editing area can be obtained, and then according to the position change amount of the input control, an action range adjustment amount corresponding to the action range adjustment instruction can be determined, wherein the action range adjustment instruction is an instruction input through the input control. Optionally, the input control may be a mouse, a keyboard or other input devices connected to the computer device, and the preset direction may be a Y-axis direction or an X-axis direction. By way of example, assuming that the resulting change in position of the input control in the Y-axis direction of the edit field is 5 pixels moved upward, the computer device may determine that the range adjustment amount corresponding to the range adjustment instruction is a 5mm radius expansion, or an n-fold expansion of 5mm, which may be set as desired.
S203, determining the updated action range of the current editing tool according to the current action range and the action range adjustment amount of the current editing tool, and displaying the updated action range.
Specifically, the computer device determines the updated scope of the current editing tool according to the current scope and the scope adjustment amount of the current editing tool. Taking the display form of the editing tool as a circle as an example, assuming that the current action range is a radius of 5mm and the action range adjustment amount is a radius expansion of 5mm, the update action range of the editing tool is 10mm. The computer device then displays the editing tool corresponding to the updated scope.
According to the medical image editing method provided by the embodiment, the computer equipment firstly acquires the current action range of the current editing tool, then analyzes the action range adjustment instruction to determine the corresponding action range adjustment quantity, and then determines the updated action range of the current editing tool according to the current action range and the action range adjustment quantity. According to the method, the current acting range of the current editing tool is taken as a reference, and the updated acting range is determined according to the acting range adjustment quantity, so that the matching degree of the updated acting range and the acting range required by a user can be improved, the correlation between the acting range adjustment quantity and the position change quantity of the input control can be further set according to the requirement, and the editing efficiency of medical images is further improved.
The specific process of analyzing the action range adjustment instruction to obtain the position variation of the input control in the preset direction of the editing area when the input control is a mouse is described in the following specific embodiment. Fig. 3 is a flow chart of a medical image editing method according to still another embodiment, where, based on the foregoing embodiment, S202 includes:
s301, acquiring the starting position and the ending position of a mouse pointer carried in the action range adjustment instruction in the editing area.
Specifically, the above action range adjustment instruction is an instruction input by a button of the trigger mouse, alternatively, an instruction input by a right button of the trigger mouse may be an instruction input by clicking the right button of the mouse to make the mouse pointer slide positively along the Y axis to expand the action range of the editing tool, and clicking the right button of the mouse to make the mouse pointer slide negatively along the Y axis to reduce the action range of the editing tool. The computer equipment can obtain the starting position and the ending position of the mouse pointer in the editing area by analyzing the action range adjustment instruction, wherein the starting position and the ending position can be represented by corresponding position coordinates. Alternatively, if the preset direction is the Y-axis direction, the start position and the end position may be represented by coordinates on the Y-axis.
S302, calculating displacement amounts of the initial position and the final position in a preset direction, and taking the displacement amounts as position change amounts of the mouse pointer on the editing area.
Specifically, after the computer device obtains the initial position and the final position of the mouse pointer in the editing area, the displacement of the initial position and the final position of the mouse pointer in the preset direction can be calculated, and the displacement is used as the position change of the mouse pointer in the editing area. By way of example, assuming that the start position of the mouse pointer in the Y-axis direction is 10 and the end position after the input of the scope adjustment instruction is 15, the amount of change in the position of the mouse pointer can be determined to be 5 pixels forward moving along the Y-axis.
Alternatively, in some embodiments, after obtaining the displacement amount of the mouse pointer, the computer device may multiply the displacement amount by a preset scale factor, and use the product result as the action range adjustment amount corresponding to the action range adjustment instruction, where the scale factor characterizes the variation amplitude of the action range adjustment amount.
Alternatively, the computer device may calculate the value according to the formula (Y new -Y old ) Determining the range adjustment amount by x beta, wherein (Y new -Y old ) Is the displacement, Y new To the end position, Y old And for the initial position, beta is a scale factor, and represents the variation amplitude of the action range adjustment quantity according to the displacement. For example, assuming that the displacement amount of the mouse pointer is 5 pixels and β is 2, the range adjustment amount of the editing tool is 10mm.
Optionally, after the computer device obtains the action range adjustment amount of the current editing tool, the computer device may adjust the current action range and the action range adjustment amountAnd summing, wherein the sum result is used as the updated action range of the current editing tool. Alternatively, the computer device may calculate the value according to the formula (Y new -Y old ) Obtaining an updated action range of the editing tool by using x beta+r, wherein r is the current action range of the current editing tool; in addition, the current action range and the action range adjustment amount may be weighted and summed to obtain the updated action range of the current editing tool. Illustratively, after clicking the right mouse button to move the mouse pointer in the positive/negative direction along the Y-axis, the range of action of the editing tool on the medical image is changed, see the schematic diagram shown in fig. 3 a.
According to the medical image editing method, the action range adjustment instruction is input through the mouse, so that familiar operation of a user on the mouse is utilized, and the medical image editing method is more convenient for the user to edit the medical image.
