Fine-tune the rough segmentation result Segmentation obtains fine segmentation results, and the method of the present invention can realize automatic segmentation of the prostate.

Description

【Technical field】 [0001] The invention relates to the field of medical images, in particular to the segmentation of the prostate in the medical images. 【Background technique】 [0002] An essential prerequisite for the successful treatment of cancer with computer-assisted radiation therapy is to confirm the location and size of the tumor while preserving critical organs around the lesion. Therefore, accurate and efficient extraction of key organ contours and calculation of gross tumor volume (GTV, gross tumor volume) are key steps in adaptive radiation therapy and surgical navigation, and have very important research significance. When lesions occur around the genitals, the genitals must be drawn separately for protection to avoid radiation exposure. Therefore, when tumors appear in the male pelvic cavity, the prostate is the first organ to avoid urgently. Moreover, prostate cancer is the most common malignant tumor of the male reproductive system, and its morbidity and mor...
