Round selection system and round selection method

Abstract

The invention relates to a circling system and a circling method, the circling system realizes a neural network circling method through an electronic device, and is used for automatically circling a preset target in a three-dimensional medical image of a patient, and the preset target is a tumor or adjacent one or more critical organs. The circling system comprises a storage unit, a processing unit and a plurality of computer operable modules. The processing unit is used for obtaining the three-dimensional image stored in the storage unit and executing a circling method to output a circling image of one or more preset targets of the image. The circling method executed by the processing unit comprises the following steps: enhancing image features of a preset target and improving the accuracy of circling by an image preprocessing module; and extracting a plurality of abstract features of the at least one preset target and restoring the abstract features to the size of the original input image by a neural network circling module to generate a circling image of the at least one preset target.

Description

technical field [0001] The invention relates to a circle selection system and a circle selection method, in particular to a circle selection system and a circle selection method which take human body images as input and recombine and transform the images. Background technique [0002] Radiation therapy is a very important part of cancer treatment. Taking head and neck cancer, which is the seventh most common cancer in the world, as an example, radiation therapy is one of the most widely used treatments for head and neck cancer. However, the key to radiotherapy planning lies in the accuracy of the tumor and adjacent organs at risk (Organs at Risk, OAR). potential side effects. [0003] Clinically, the selection of treatment planning must rely on radiation oncologists to hand-select the tumor tissue and multiple adjacent critical organs in each image one by one based on the obtained high-resolution computed tomography simulation images. This hand-drawn circle selection proce...

Problems solved by technology

This hand-drawn circle selection process takes an average of four hours for the physician to complete the circle selection work for a patient, resulting in a delay in the time point for early treatment of the patient, and even hinders the intensive re-establishment of the radiation treatment plan according to the course of treatment
