Embodiment
[0046] like figure 1 As shown, the present invention discloses a method for quickly modifying the outline of a radiotherapy target area, which includes the following steps:
[0047] S1. Obtain the structure list of the radiotherapy target area image, each image corresponds to an independent structure list, and obtain the mouse state at the same time, the structure list refers to all the structures outlined by the doctor in a medical image. After the medical image is displayed, the system used by the doctor will read the structure list corresponding to the image from the database, so as to display different delineation results in the image.
[0048] In the above step S1, the system obtains the structure list of the image through network transmission with the server; through the MouseEvent interface of the browser, the state when the user interacts with the pointing device (such as a mouse) is obtained
[0049] S2. Monitor the mouse movement position, specifically through the M...

Abstract
The invention discloses a method for rapidly modifying the contour line of a radiotherapy target area, comprising: S1, obtaining a structure list of images of the radiotherapy target area; S2, monitoring the mouse movement position; S3, recording the mouse position coordinates when the mouse is pressed, Record it as the starting point P1 of the new outline; S4, determine whether P1 is close to other outlines, if so, return to S1; S5, determine whether P1 is close to the currently selected structure, if not, return to S1; S6, determine the mouse Whether to drag the state, if not, jump to S8; S7, draw a new outline track formed by P1 and Pn; S8, judge whether the mouse is released, if not, continue to return to S6; S9, record the coordinates of the mouse release position, record P2 is the end point of the new outline; S10, judge whether P2 is close to the currently selected structure, if not, clear P1, Pn, P2; S11, merge the old and new outlines. The invention can greatly reduce the complex operation brought about by the process of delineating the outline of the target area, and improve the delineation performance of the radiotherapy system.
Description
technical field [0001] The invention belongs to the technical field of delineating the outline of a target area, and relates to a method for quickly modifying the outline of a radiotherapy target area. Background technique [0002] Tumor radiation therapy is one of the three major tumor treatment techniques at present. Accurate radiotherapy for malignant tumors relies on computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), cone beam computed tomography (CBCT) technologies and corresponding intelligent processing of medical image information technology. Delineating the tumor target area and surrounding organs at risk on radiotherapy positioning images is the premise and key technology for successful implementation of precise radiotherapy. [0003] Most clinical target delineation is done by radiotherapists on commercial treatment systems (Moncaco, Pinnacle, etc.) developed by manufacturers. In recent years, with the rapid developm...
