Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a method for line correction is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
The closed-loop line profile is a profile formed by drawing a line closure by operating a brush in a marking tool, the marking tool can be any marking tool on the market, and the closed-loop line profile can be formed by a plurality of curve points. That is, the closed-loop line profile is composed of a plurality of curve points, and the curve point is the minimum unit constituting the closed-loop line profile.
In particular, the end user may draw a curve of at least one edge seal in the marking tool through the associated tool as a closed-loop line profile.
And step 104, acquiring the position of the current reference point, and matching the current point from the multiple curve points to obtain a target curve point, wherein the target curve point has an association relation with the current reference point.
During the process of drawing the line, a closed-loop line profile is drawn, the operation acting on the closed-loop line profile is detected, and the position of the current reference point is determined according to the operation, wherein the operation comprises but is not limited to click operation or voice operation. For example, the terminal user draws a closed-loop line profile, clicks and selects a point on the closed-loop line profile using a mouse or a finger, the selected point may be used as a current reference point, and a position of the current reference point is obtained according to the current reference point.
Specifically, according to the position of a mouse operated by a terminal user, the position of the mouse is obtained and used as the position of the current reference point, meanwhile, the positions of all curve points forming the closed-loop line profile are obtained, and the target curve points are obtained through matching from the plurality of curve points according to the position of the current point. The matching mode of obtaining the target curve point by matching from the multiple curve points according to the position of the current point can be customized, and the customization can be to calculate the distance difference between the position of the current reference point and the position of each curve point, and take the curve point corresponding to the distance difference meeting the preset condition as the target curve point. Specifically, the distance difference between the position of the current reference point and the position of each curve point may be calculated by using a cubic B-spline curve difference function, specifically, the distance difference between the position of the current reference point and the position of each curve point is calculated by using the cubic B-spline curve difference function, and the curve point corresponding to the minimum distance difference is used as the target curve point.
The association relationship here means that the target curve point and the current reference point have close relation, and may share a circle center, or the distances from the target curve point and the current reference point to the circle center are equal, or the distance between the target curve point and the current reference point passes through the circle center.
And 106, determining a line segment to be dragged and a fixed line segment from the closed-loop line profile according to the target curve point and the current reference point.
After the target curve point matched with the current reference point is determined, the current reference point and the target curve point are points in the closed-loop line profile, and therefore the line segment to be dragged and the fixed line segment can be determined from the closed-loop line profile according to the target curve point and the current reference point. The line segment to be dragged is used for dragging and revising, and the fixed line segment is the line segment which is kept unchanged when the line segment to be dragged is dragged, so that the line segment where drawing abnormality is located in the closed-loop line outline can be determined as the line segment to be dragged, and the line segment where drawing is not correct in the closed-loop line outline is determined as the fixed line segment. The abnormal detectable line segment and the line segment with unmatched preset track are drawn in the closed loop line outline to serve as the abnormal line segment, the preset track of each line segment can be set in advance, and the preset track corresponding to each line segment is the correct line segment of the line segment.
And 108, acquiring a dragging instruction, dragging the line segment to be dragged according to the dragging instruction to obtain a target closed-loop line profile, wherein the target closed-loop line profile is obtained by combining the line segment to be dragged and the fixed line segment.
After the line segment to be dragged and the fixed line segment are determined from the closed-loop line profile according to the target curve point and the current reference point, the line segment to be dragged and the fixed line segment can be combined to obtain the target closed-loop line profile after the line segment to be dragged and the fixed line segment are dragged. Specifically, after determining the segment to be dragged and the fixed segment from the closed-loop line profile according to the target curve point and the current reference point, the terminal user may use the target curve point as the reference point, click the target curve point with a mouse to generate a dragging instruction, drag the segment to be dragged in the closed-loop line profile according to the dragging instruction, drag the segment to be dragged to the fixed segment for combination, and finally obtain the revised target closed-loop line profile.
The line correction method comprises the steps of obtaining positions of current reference points on a closed-loop line outline and a closed-loop line outline, matching the positions of the current reference points from a plurality of curve points to obtain a target curve point with an incidence relation, obtaining a dragging line segment and a fixed line segment corresponding to the target curve point and the current reference point due to the fact that the line segment to be dragged and the fixed line segment exist between the target curve point and the current reference point, and combining the line segment to be dragged and the fixed line segment to obtain the target closed-loop line outline by dragging the line segment to be dragged. If drawing errors occur in the line drawing process, all contour curves drawn previously do not need to be erased, the line segment to be dragged and the fixed line segment only need to be determined according to the current reference point and the target curve point, the line segment to be dragged is dragged according to the dragging instruction, the line segment to be dragged and the fixed line segment are combined, the line segment to be dragged and the fixed line segment do not need to be drawn again, and the drawing efficiency is improved.
In one embodiment, as shown in fig. 2, the obtaining of the target curve point by matching from a plurality of curve points according to the position of the current point includes:
And step 204, taking the curve point corresponding to the minimum position difference value in all the position difference values as a target curve point.
The target curve point is determined and obtained according to the position of the current point and the positions of the curve points, and specifically, the target curve point may be determined and obtained by calculating a position difference between the position of the current point and the positions of the curve points according to a cubic B-spline difference function. The cubic B-spline curve difference function is an interpolation algorithm, and a curve function set is obtained mathematically by solving a three-bending moment equation set through a smooth curve of a series of shape interpolation points.
Specifically, a preset cubic B-spline curve difference function is obtained, the position of the current point and the positions of the curve points are used as input parameters of the cubic B-spline curve difference function, and the position difference corresponding to the position of the current point and the positions of the curve points is calculated through the cubic B-spline curve difference function. Further, the target curve point is determined according to each position difference value calculated by the cubic B-spline difference function, and specifically, the curve point corresponding to the minimum position difference value among the position difference values may be used as the target curve point. That is, the target curve point is the curve point closest to the position where the current point is located, and the closed-loop line profile is revised by the closest curve point.
In an embodiment, as shown in fig. 3, acquiring a dragging instruction, dragging a to-be-dragged line segment according to the dragging instruction, and obtaining a target closed-loop line profile, where the target closed-loop line profile is obtained by combining the to-be-dragged line segment and a fixed line segment, and the method includes:
And 304, dragging the segment to be dragged according to the dragging instruction by taking the target curve point as a reference point, and combining the segment to be dragged and the fixed segment to obtain the target closed-loop line profile.
The dragging instruction is used for dragging the closed-loop line profile and can be generated by clicking the closed-loop line profile by a terminal user. Specifically, after a dragging instruction generated by a terminal user through the triggering of a marking tool is obtained, the obtained target curve point is determined to be used as a reference point, the segment to be dragged is dragged according to the dragging instruction, and the segment to be dragged and the fixed segment are fused to obtain a target closed-loop line profile. In an actual application scene, a mouse clicks a target curve point, a segment to be dragged is dragged within the dragging range of the target curve by taking the target curve point as a reference point, and the dragging of the segment to be dragged is fused with a fixed segment to obtain a target closed-loop line profile. As shown in fig. 4, fig. 4 is a schematic view of a scene of a closed-loop line profile revision process in an embodiment, where a in fig. 4 is a closed-loop line profile before revision, and b in fig. 4 is a target closed-loop line profile after revision. Once the closed-loop line contour is drawn in a wrong way or in a wrong way, the drawn closed-loop line contour is not required to be erased, and only part of the wrongly drawn closed-loop line contour is required to be revised, so that the drawing efficiency of the closed-loop line contour is improved.
In one embodiment, as shown in fig. 5, the line modification method further includes:
The closed-loop line wiping instruction is an instruction for wiping a closed-loop line, and the closed-loop line wiping instruction may be generated by a terminal user through triggering of a related control in a marking tool, for example, an eraser tool in the marking tool, and the terminal user clicks the eraser tool in the marking tool to generate the closed-loop line wiping instruction. The closed-loop line wiping instruction carries a closed-loop line segment identifier, the closed-loop line segment identifier is used for uniquely identifying a line segment in a closed-loop line profile, and the closed-loop line profile line segment can be composed of a preset number of curve points. That is to say, the closed-loop line profile is composed of a plurality of closed-loop line profile line segments, and the closed-loop line profile line segments are composed of a preset number of curve points, wherein the preset number of curve points corresponding to each closed-loop line profile line segment may be the same preset number of curve points or different preset numbers of curve points. The preset number may be specifically set or adjusted according to a service requirement or an actual need.
And step 504, wiping the line segment corresponding to the closed-loop line segment identification according to the closed-loop line wiping instruction to obtain a missing line region.
After the closed-loop line wiping instruction is obtained, the line segment corresponding to the closed-loop line segment identification is wiped according to the closed-loop line wiping instruction, and therefore the missing line area is obtained. As shown in fig. 6, fig. 6 is a scene schematic diagram illustrating a closed-loop line profile wiping process in an embodiment, where a in fig. 6 is to wipe a line segment corresponding to a closed-loop line segment identifier according to a closed-loop line wiping instruction to obtain a missing line. The missing part in the closed-loop line profile a in fig. 6 is the missing line region wiped according to the closed-loop line wiping instruction.
The line drawing instruction is used for drawing the missing line area, and the corresponding line segment can be drawn according to the line drawing instruction. That is, outside the closed-loop line contour, a corresponding line segment may be drawn according to the line drawing instruction, as shown in b in fig. 6, where b in fig. 6 is the corresponding line segment drawn according to the line drawing instruction. And further, after drawing the corresponding line segment according to the line drawing instruction, fusing the line segment with the missing line region to obtain the target closed-loop line profile. Specifically, as shown in c in fig. 6, the initial coordinate position of the previous missing line region is obtained, the initial coordinate position of the line segment drawn according to the line drawing instruction is obtained, and the initial coordinate position of the missing line region and the initial coordinate position of the line segment drawn according to the line drawing instruction are set to be the same initial coordinate position; similarly, the ending coordinate position of the previous missing line region is obtained, the ending coordinate position of the line segment drawn according to the line drawing instruction is obtained, the ending coordinate position of the missing line region and the ending coordinate position of the line segment drawn according to the line drawing instruction are set to be the same ending coordinate position, finally the line segment drawn according to the line drawing instruction and the missing line region can be fused together, and the presented effect can be shown as c in fig. 6.
In one embodiment, as shown in fig. 7, the target closed-loop line profile is a medical image data profile, and the line modification method further includes:
The target closed-loop line profile is a medical image data profile, the medical image data is DICOM image data, the DICOM image data is Digital Imaging and Communications in Medicine (DICOM), the DICOM image data is an international standard for medical images and related information, and the DICOM medical image plays an important role in treating doctors in a medical application scene. That is, the contour in the medical data image can be drawn by the labeling tool, and then the drawn closed-loop line contour is revised to obtain the target closed-loop line contour, and the target closed-loop line contour is the DICOM image data contour.
Specifically, corresponding medical image data is obtained according to the medical image data contour, the medical image data includes corresponding data tags, and each data tag includes a corresponding tag value. And if a plurality of target closed-loop line profiles exist, acquiring corresponding medical image data according to each medical image data profile. Wherein the acquired medical image data comprises corresponding data tags, wherein the data tags are used to identify the corresponding medical image data, and the data tags comprise corresponding tag values. I.e. the corresponding medical image data is identified by the tag value.
The window width and window level information is a proper noun in the medical image data, and different window width and window levels used at different positions can sufficiently reflect anatomical content and focus image expression, so that the corresponding window width and window level information in the medical image data needs to be acquired, and the acquired window width and window level information can be adjusted or set according to different positions. The window width and window level information can influence the focus image expression in the medical image data, and plays an important role in doctors in medical scenes. Therefore, in the annotation tool of the line modification method, the doctor can adjust or set the window width and window level information in the medical image data through the annotation tool.
And step 708, displaying window width and window level information corresponding to the sorted medical image data.
In order to conveniently display the window width and window level information of the plurality of medical image data to a doctor, the plurality of medical image data can be sorted to obtain the sorted medical image data, and then the window width and window level information corresponding to the sorted medical image data is displayed to the doctor for adjustment. In this way, a plurality of disordered medical image data can be displayed to a doctor in order, and the doctor can improve the processing efficiency and the like. Specifically, since the medical image data includes the corresponding data tag and the data tag includes the corresponding tag value, the tag value corresponding to the data tag of each medical image data can be obtained, and the tag values are arranged in a descending order or an ascending order according to a preset rule to obtain each sorted medical image data. And finally, displaying window width and window level information corresponding to the sequenced medical image data at the front end of the terminal. For example, sorting medical image data, for example, a sequence of medical image data, for example, 20 medical image data, placed in a certain folder may be sorted according to the size of the label value in each medical image data, and the images may be displayed in order after sorting, so that it can be indicated whether the patient is in order when scanning ct, for example, first-in-order or first-out-order.
And 710, generating an editing instruction according to the clicking operation of the user on the window width and window level information in the displayed sequenced medical image data, and editing the window width and window level information in the medical image data according to the editing instruction.
Specifically, after the front end of the terminal displays the window width window level information corresponding to the sorted medical image data, a terminal user, for example, a doctor may perform operation processing according to the window width window level information corresponding to the sorted medical image data, specifically, may generate an edit instruction for a click operation on the window width window level information in the sorted medical image data, and edit the window width window level information in the medical image data according to the edit instruction. In one embodiment, an end user, such as a doctor, may move a mouse event that adjusts a window width and a window level in medical data through a mouse, and then generate a request message requesting parameters in real time according to the mouse event, where the request message includes the request parameters, and the request parameters are window width and window level adjustment parameters, and then adjust window width and window level information in the selected medical data according to the window width and window level adjustment parameters.
In one embodiment, as shown in fig. 8, generating an editing instruction according to a user's clicking operation on the displayed sorted medical image data, and editing the window width information in the medical image data according to the editing instruction includes:
The mouse event refers to an event generated by a terminal user through mouse adjustment of a window width and window level in medical image data. Specifically, after the front end of the terminal displays the window width and window level information corresponding to the sorted medical image data, a terminal user can adjust or set the displayed window width and window level information, and specifically, a mouse event can be generated by adjusting the window width and window level of the medical image data through mouse movement.
Specifically, the terminal may generate a request message requesting parameters according to the generated mouse event, that is, the mouse event may be used to generate the request message. The request message is a message for requesting adjustment of window width and level information in the selected medical data. The request message carries a request parameter, and the request parameter is an adjustment parameter of the window width level, which is a parameter that the window width level in the medical data needs to be adjusted to be specified.
In step 806, the window width and level information in the medical image data is adjusted to the window width and level specified by the request parameters in the request message.
Specifically, after the request message requesting the parameters is generated in real time according to the mouse event, the window width and level information in the medical image data needs to be adjusted to the window width and level specified by the request parameters in the request message. That is, an end user, for example, a doctor may adjust window width and window level information in medical image data through a labeling tool, while different portions use different window widths and window levels to facilitate study of a lesion area, and adjust window width and window level information in medical data to appropriate window widths and window levels to facilitate study and search of a lesion area in a medical image, and at the same time, improve the processing efficiency of the doctor.
