Intraoperative registration method and device, storage medium and server

Abstract

The embodiment of the invention provides an intraoperative registration method and device, a storage medium and a server. The method in the embodiment of the invention comprises the steps of acquiringa focus image; performing coarse registration on the focus image through a non-rigid registration algorithm and a probe to generate an initial matrix; through an iterative nearest point algorithm, generating a registration matrix according to a pre-collected source point set, a pre-generated target point set and an initial matrix, registration equipment does not need to be purchased, and the registration cost can be saved; the registration precision is ensured, so that the precision of a navigation operation is ensured, and the operation safety is further improved; the consumed time is short,and accurate registration can be efficiently realized.

Description

【Technical field】 [0001] The invention relates to the technical field of computer-aided medical treatment, in particular to an intraoperative registration method, device, storage medium and server. 【Background technique】 [0002] With the emergence of computer-aided diagnosis, especially the realization of image-guided surgery, doctors can understand the patient's condition according to the three-dimensional image of the human lesion before operation and then make a plan during the operation. Image-guided surgery is a widely used clinical surgery that integrates many advantages such as accurate lesion localization, less intraoperative trauma, and high surgical success rate. Usually doctors use the intraoperative cone-beam CT (Cone-beam CT, CBCT for short) registration method or the intraoperative X-ray 2D-3D registration method for registration, and guide the doctor to track the location of the lesion relative to the patient in real time during the operation, so that It can...

Problems solved by technology

Usually doctors use the intraoperative cone-beam CT (Cone-beam CT, CBCT for short) registration method or the intraoperative X-ray 2D-3D registration method for registration, and guide the doctor to track the location of the lesion relative to the patient in real time during the operation, so that It can achieve the goal of accurately resecting the lesion according to the doctor's plan or accurately implanting steel nails and other devices. However, if the intraoperative CBCT registration method is used, CBCT equipment needs to be purchased, resulting in increased costs and more radiation times for patients during the operation. The patient’s body will cause certain injuries, and the CBCT images are not accurate enough and have large errors; if the intraoperative X-ray 2D-3D registration method is used, this registration algorithm is more complicated, takes a long time, and the registration efficiency is low, resulting in Surgery is less safe
