Abstract

The embodiment of the invention provides an automatic lymph node sketching method and device, and the method comprises the steps: obtaining a patient image of a to-be-sketched lymph node, carrying outthe preprocessing of the patient image, and obtaining an interested region image; inputting the region-of-interest image into a lymph node segmentation model to obtain a binary image representing a lymph node region; performing post-processing on the binary image representing the lymph node area to obtain a lymph node sketching result, wherein the lymph node segmentation model is obtained by taking a preprocessed patient image sample as a first channel input, taking lymph node transition probability information based on priori knowledge as a second channel input, and taking lymph node data manually sketched by a doctor corresponding to the patient image sample as a sample label for training. According to the embodiment of the invention, the problems of long consumed time, inaccurate sketching and low segmentation precision of the existing lymph node sketching method can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, and more specifically, to a method and device for automatic lymph node delineation. Background technique [0002] As one of the important means of cancer treatment, radiotherapy needs to accurately define and outline the gross tumor (Grosstumor volume, GTV), clinical target volume (CTV), planning target volume (Planning target volume, PTV), endangered organs ( Organ atrisk, OAR) and Planning organ atrisk volume (PRV). Among them, gross tumor GTV refers to the gross tumor area visible in clinical physical examination or imaging examination, including the primary tumor (GTVp) and metastatic regional lymph nodes (GTVn). Accurate GTV delineation can effectively reduce the probability of tumor recurrence and reduce the side effects of radiotherapy. [0003] At present, the delineation of metastatic regional lymph nodes (GTVn) is mainly done manually by doctors, which relies ...
