Abstract

The invention discloses a one-stop vertebral tumor microwave ablation operation simulation method and device, and relates to the technical field of medical instruments and simulation, and the method comprises the following steps: obtaining a magnetic resonance image of a patient before an operation, carrying out the image segmentation of the magnetic resonance image, and building an individual model of the patient based on the segmented image; collecting magnetic resonance temperature measurement data when the phantom is heated, calculating distribution of heat source items according to the magnetic resonance temperature measurement data, and establishing a microwave probe model based on the distribution of the heat source items; conducting temperature simulation on different needle inserting positions, located in the individual model, of the microwave probe model, conducting thermal damage evaluation on temperature simulation results to determine the optimal needle inserting position and heating duration, and an operation simulation scheme of the to-be-ablated area is generated. The method can be used to assist doctors in quickly and accurately determining proper needle inserting positions and microwave heating parameters, and high dependence on experience of the doctors is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment and simulation, in particular to a one-stop simulation method and device for microwave ablation of vertebral tumors. Background technique [0002] Due to the rich blood supply and close association with regional lymphatic and venous drainage systems, vertebrae are prone to metastatic lesions. Under normal circumstances, osteoblasts and osteoclasts are responsible for forming new bone and dissolving old bone respectively. The two are in a dynamic balance. When cancer cells When the action of one of these cells is blocked or accelerated, the balance is upset, resulting in lytic or bony lesions. Compared with traditional surgical resection, image-guided thermal ablation of vertebral tumors has gradually attracted attention because of its minimal or even non-invasive and less blood loss. [0003] Abnormal development causes tumor cells to consume energy quickly, produce a large amount of me...
