Abstract

The invention relates to a liver tumor segmentation method and system based on deep learning. The method comprises the following steps: preprocessing a collected data set; a network model being built according to the preprocessed data, wherein the network model comprises a plurality of lower convolution layers and a plurality of upper convolution layers, the lower convolution layers are connected to the upper convolution layers through jumping, and feature maps obtained by the lower convolution layers are connected with the upper convolution layers through an attention module on jumping connection; inputting the preprocessed data into the network model for training to obtain an optimal network model; and segmenting a to-be-processed CT image by using the optimal network model to obtain a liver tumor region. According to the invention, wrong segmentation can be reduced, and high precision can be obtained.

Description

technical field [0001] The present invention relates to the technical field of medical image processing and application, in particular to a liver tumor segmentation method and system based on deep learning. Background technique [0002] In recent years, with the development of today's society, CT / MRI imaging has been widely used in the field of medical imaging. Doctors often need to manually segment the lesion area in CT / MRI images before making a diagnosis, so as to provide assistance for subsequent surgical planning and tumor treatment evaluation. However, this manual segmentation method is not only time-consuming and labor-intensive, but also susceptible to segmentation differences caused by the subjective judgment of doctors. Therefore, the use of computer algorithms to realize the automatic segmentation of liver tumors in CT / MRI images can greatly reduce the workload of doctors, and at the same time improve the accuracy and repeatability of liver tumor segmentation ser...
