Abstract

The present invention relates to a method for analyzing image data of central nervous system tumors, comprising: S1, obtaining the image data of central nervous system tumors; S2, automatically extracting the features in the image data by using the LASSO algorithm, and analyzing the features Perform linear combination to obtain the first classification probability, and use the first classification probability as the first classification dimension; S3, generate several decision trees based on the random forest algorithm according to the characteristics, and then obtain the second classification probability according to the decision tree, Using the second classification probability as a second classification dimension; S4. Using the first classification dimension and the second classification dimension as a first two-dimensional feature, obtaining a third classification probability based on a two-dimensional SVM algorithm, and using the The third classification probability is used as the first classification result, combined with this analysis method to improve the accuracy of central nervous system tumor shadow classification.

Description

technical field

[0001] The invention relates to the field of medical imaging, in particular to a method for analyzing image data of central nervous system tumors. Background technique

[0002] Central nervous system tumor is a clinically common tumor, but due to the particularity of the site, high tumor invasiveness, high recurrence rate, and high drug resistance to traditional radiotherapy and chemotherapy, despite the continuous advancement of surgery, radiotherapy, and chemotherapy techniques, The relevant clinical treatment effects at home and abroad have progressed very slowly in the past 30 years. With the advancement of information technology, medical imaging data is showing an explosive growth trend. How to use these data systematically and comprehensively, continuously innovate life science theory and technology, study the mechanism of its occurrence, development and treatment resistance, and further explore new effective treatment methods. It has become a new top...
