Description

technical field [0001] The invention belongs to the technical field of three-dimensional reconstruction of brain tumor medical images, and in particular relates to an interactive method and system for three-dimensional reconstruction and display of brain tumor medical images. Background technique [0002] Brain tumors include primary brain tumors and brain metastases. The best treatment method is complete surgical resection. However, due to the important functions of normal brain tissue and the characteristics of extensive infiltration of malignant tumors into the brain, malignant brain tumors, especially Complete resection of glioma blasts is impossible. Brain tumors include intracranial, extracerebral, and intracerebral tumors. Intracranial and extracerebral tumors are mostly benign tumors, including meningioma, pituitary tumor, schwannoma, craniopharyngioma, and primary intracerebral tumors are mostly malignant tumors, including glioma, neuroblastoma, lymphoma and Metas...
