Abstract

The invention relates to an evaluation system and method for the efficacy of synchro-neoadjuvant chemoradiotherapy before the rectal cancer surgery. The evaluation system comprises an image acquisition unit used for acquiring pathological biopsy slice scan images and neoadjuvant chemoradiotherapy treatment pre-MRI images of newly diagnosed locally advanced rectal cancer patients, and classifying the rectal cancer patients into a training set, a check set and a test set, to serve as input image data, an image labeling unit used for respectively labeling the pathological biopsy slice scan imagesand the MRI images of the training set, the check set and the test set, a convolutional neural network constructing unit used for constructing a first convolutional neural network model, and a convolutional neural network model training unit used for obtaining a second convolutional neural network model for evaluating the efficacy of synchro-neoadjuvant chemoradiotherapy before the rectal cancersurgery. The evaluation system for the efficacy of synchro-neoadjuvant chemoradiotherapy before the rectal cancer surgery has multiple advantages such as being high in accuracy, short in time consumption, long in working duration, objective and three-dimensional.

Description

technical field

[0001] The present invention relates to a system and method for evaluating curative effect of preoperative neoadjuvant chemoradiotherapy for rectal cancer, in particular to a system and method for evaluating curative effect of preoperative neoadjuvant chemoradiotherapy for rectal cancer based on big data analysis of biopsy pathology and pre-treatment MRI images. Background technique

[0002] Deep learning is currently the most suitable and widely used algorithm for image recognition and speech analysis in the field of artificial intelligence. Its inspiration comes from the working mechanism of the human brain. It is to automatically extract features from externally input data by establishing a convolutional neural network. , so that the machine can understand the learning data, obtain information and output. At present, artificial intelligence based on deep learning has been applied in various industries, including speech recognition, face recognition, car lo...
