Image guided registration system for abdominal surgery interventional operation, and related device

Abstract

The invention discloses an image guided registration system for abdominal surgery interventional operation, and a related device. An image guided registration method for the abdominal surgery interventional operation comprises the steps that firstly, the registration result of a physical space and a preoperative image space is obtained; then abdominal characteristic point sets corresponding to abdominal surface images when a patient is in different respiration states are obtained, a depth camera is utilized to conduct corresponding processing on the abdominal surface images and preoperative abdominal surface images, and thus multiple intraoperative characteristic point sets and multiple preoperative abdominal characteristic point sets are obtained; and finally, according to the registration result of the physical space and the preoperative image space, a reference system of the intraoperative characteristic point sets is transformed into an intraoperative image space, in the intraoperative image space, deformable registration is conducted on the intraoperative characteristic point sets and the multiple abdominal characteristic point sets, thus the purpose of real-time registrationof the intraoperative image space of the patient in the different respiration states and the physical space is achieved during operation, and the precision of image registration in the abdominal surgery interventional operation process is improved.

Description

technical field

[0001] The present application relates to the technical field of image processing, and more specifically, to an image navigation and registration system and related devices for abdominal surgical intervention. Background technique

[0002] The Image Guided System (Image Guided System) refers to a system that scans medical images through medical imaging equipment, thereby providing image guidance for doctors in the operation process of patients. Through this system, doctors can obtain the internal structure and physiological information of the patient's body during the treatment process, so that they can accurately judge the current treatment status (such as the position of the treatment device in the patient's body, the dynamic size of the ablation area of ​​the lesion, and whether there is a problem due to puncture failure). leading to internal bleeding, etc.). Compared with the traditional non-image-guided surgical method, the image navigation system is co...
