Abstract

Embodiments of the invention disclose an automatic target delineation method and device in a radiotherapy plan, and an electronic device. The method includes the steps of receiving an input image, identifying the input image by using a pre-stored ROI (region of interest) list, obtaining a suspected region in the input image and delineating the suspected region in the input image, the input image including at least one organ image, and an image of multiple known regions of interest being saved in the region of interest list; and inputting the input image with the delineated suspected region to a pre-trained full convolutional neural network, and outputting a target delineated image with at least one region of interest. According to the embodiments of the invention, in a radiotherapy planning system, an endangered organ, an irradiation target region and the like are automatically delineated in a positioning image of a patient before a plan is made for the patient, a great deal of manual operations by physicians and physicists are reduced, and a very high application value is gained in a radiotherapy department.

Description

technical field [0001] The invention relates to a target-picking technology in radiotherapy planning, in particular to an automatic target-picking method, device and electronic equipment in radiotherapy planning. Background technique [0002] The radiotherapy planning system is based on the positioning image taken by the patient. The doctor outlines the outline and important organs. The physicist outlines the tumor target area GTV, clinical target area CTV and other target areas. The physicist sets the radiation field according to the target area and prescription. , dose optimization design. [0003] In the existing planning system, the delineation of the target area consumes a lot of energy, and the automatic delineation implemented by some manufacturers is difficult to meet the doctor's requirements. Generally, after the automatic delineation is completed, a large number of modifications are required. Contents of the invention [0004] A technical problem to be solved b...
