Abstract

An exemplary method of determining an actual surgical path for a patient based on a pre-planned surgical path may include extracting (301) a first two-dimensional image of the patient associated with information collected at a first point in time ( block 210). A first coordinate system (380') describes a spatial relationship between the patient and a device in the operating room. The method further includes modifying a three-dimensional model of the patient including the pre-planned surgical path with a first set of modified parameter values ​​(302). A second coordinate system (380) describes the three-dimensional model (302), constructed from information collected at a second point in time earlier than the first point in time (block 220). The method further comprises: extracting a second 2D image (303) from the modified 3D model (302') (block 260); computing the first 2D image (301) and the second 2D image ( 303) between a first correlation (block 270); and converting the pre-planned surgical path to the first coordinate system (380') based on the first set of modified parameter values, thereby identifying the actual surgical path (Block 290).

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 62 / 171,245, filed June 5, 2015, entitled "Brain Navigation Method." The above provisional application and any related attachments are hereby incorporated by reference. technical field [0003] The present invention relates to an intraoperative tracking method, in particular to a method for determining an operation path. Background technique [0004] Common brain diseases such as brain tumors, Parkinson's disease, and epilepsy not only greatly reduce the quality of life of patients, but sometimes directly endanger the lives of patients. Such patients are usually treated with invasive surgery if their symptoms cannot be improved after conservative treatment such as drugs or physical therapy. [0005] Generally speaking, a surgeon plans a surgical path to a target surgical site based on specific preoperative data. However, the preplanned surgical path may need to be modifie...
