Method and system for fast planning in ablation surgery

Abstract

The invention relates to fast planning during surgeries and discloses a method and system for fast planning in an ablation surgery. The system comprises an input device, a calculation device and an output device. The calculation device acquires an actual position of an ablation probe relative to a tumor and a tumor boundary, an ablation range and ablation parameter quantitative relation of the ablation probe and a maximum ablation range parameter of the ablation probe through an input device; ablation parameters of the ablation probe are acquired according to acquired information through the calculation device and outputted through the output device to obtain corrected planning ideas. The problem of probability of incomplete ablation caused by deviation of an actual probe insertion position from a pre-surgical planned probe insertion position in the clinical ablation surgery is solved, accurate control of thermal dose in a focal zone is realized, and ablation effectiveness is guaranteed.

Description

technical field [0001] The present application relates to intraoperative rapid planning technology, in particular to a rapid intraoperative planning system and method for ablation therapy. Background technique [0002] In recent years, minimally invasive tumor ablation therapy has developed rapidly. Local tumor ablation therapy is a treatment method that uses imaging equipment to guide precise positioning, inactivate tumor cells in situ, reduce tumor burden, relieve local symptoms, and improve prognosis. The most commonly used ablation methods mainly include cryoablation, radiofrequency ablation, and microwave ablation, which have been widely used in the treatment of benign and malignant tumors such as liver, lung, kidney, bone, thyroid, breast, and lymph nodes. [0003] Local ablation therapy for tumors also includes multimodal ablation. Multimodal ablation is a combination of two minimally invasive ablation methods, cryoablation and radiofrequency ablation. Through rapid...
