Description

technical field [0001] The present invention relates to the field of medical image analysis technology and application, in particular to a machine learning-based intelligent selection method, system, equipment and medium for brain tumor radiotherapy. Background technique [0002] Brain tumors include primary brain tumors originating from intracranial cells and metastatic brain tumors transferred from other organs, more than half of which are malignant tumors. Brain tumors have the characteristics of fast growth, high recurrence rate and high disability rate. characteristics, seriously threatening human life and health. Radiation therapy is an important treatment for brain tumors, which can improve the survival rate and quality of life of patients with brain tumors. [0003] With the continuous updating of radiotherapy technology and equipment, conventional radiotherapy, stereotactic radiotherapy (SRT), helical tomotherapy (TOMO), gamma knife, brachytherapy, proton radiother...
