A tumor classification system based on radiomics

Abstract

The present invention provides a radiomics-based tumor classification system, including: lesion area extraction, used to extract lesion data; heterogeneous area extraction, using a clustering method to extract all initial heterogeneous areas in the lesion data, and then Determine the final clustering result based on the connectivity and number of pixels of the clusters on the image, and find out multiple heterogeneous regions; parameter vector extraction, extract the shape, state and other parameters of each heterogeneous region; type group extraction, The clustering method is used to divide each heterogeneous area into clusters to obtain multiple categories. New lesion type determination is used to determine which type each heterogeneous type of new lesion belongs to. The new lesion typing result is used to output the new lesion typing result. The tumor typing system of the present invention has the advantages of non-invasiveness, non-intervention, repeatability, etc., and its analysis object is based on all lesion tissues, and the information is comprehensive.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and in particular relates to a radiomics-based tumor classification system. Background technique [0002] With the prolongation of the average life expectancy of human beings, the threat of cancer to human beings has become increasingly prominent, and it has become the first cause of death of urban and rural residents in our country. Taking breast cancer as an example, breast cancer refers to malignant tumors occurring in breast ductal epithelium. It is one of the most common malignant tumors in women, with an incidence rate of 23 / 100,000, accounting for 7-10% of all kinds of malignant tumors in the whole body. Between the ages of 45 and 55, and showing an increasing trend year by year, especially Shanghai, Beijing, Tianjin and the coastal areas are the high incidence areas of breast cancer in my country. The establishment of breast cancer screening and early diagnosis system can...

Problems solved by technology

Clinicopathological diagnosis generally uses puncture or surgical biopsy, which not only causes trauma to the body, but also shows certain limitations. The pathological morphology of the same region may be different, and the degree of differentiation may vary greatly in different regions; similarly, the heterogeneity of breast cancer It may also make the molecular typing and immunohistochemical detection results obtained by gene chip technology not completely consistent
