A navigation method and system for abdominal surgery

Abstract

The invention is applied to the field of communication, and provides a method for navigating an abdominal surgery operation. The method comprises the steps that a first preset algorithm is utilized for automatically extracting mark points from a CT or MR image which is collected before the operation and provided with mark point information so as to obtain mark point set information in pre-operation image space; in the operation process, an image obtaining device is used for obtaining an RGB image and a depth image of an operation area of a patient; the depth image is used for converting two-dimensional mark point coordinate information into three-dimensional coordinates so as to obtain mark point set information of intra-operative physical space; point pair matching operation is carried out on an obtained mark point set of the pre-operation image space and an obtained mark point set of the intra-operative physical space; a conversion result, obtained through registration, of the image space and the physical space is applied to beginning to start the real-time navigation process. The invention further provides a system for navigating the abdominal surgery operation. The method and system for navigating the abdominal surgery operation can improve the navigation precision of the abdominal operation and the safety of the abdominal operation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a navigation method and system for abdominal surgery. Background technique [0002] Traditional surgical navigation systems based on markers require manual intervention in the selection of preoperative and intraoperative markers. The selected markers are highly subjective and unstable, and the results selected by different operators are different. However, the results obtained by the same operator at different times are also inconsistent, and manual intervention may also lead to potential errors in the selection of marker points, which have a significant impact on the final registration results and directly affect the accuracy of navigation. If the surgeon is not satisfied with the registration results and needs to re-register, all the pre-operative and intra-operative markers need to be re-selected, that is, the registration process is not traceable and repeatable. On the othe...
