Abstract

The invention relates to an MR (Mediated Reality)-based surgical navigation system, equipment and method as well as a storage medium. A coordinate origin data set of a corresponding lesion is acquiredthrough a probe unit and a camera unit to obtain a three-dimensional image coordinate model, and then physical coordinate information and eye calibration information corresponding to an MR projectionunit are acquired, so that the MR projection unit displays three-dimensional image information which is superimposed with the lesion of a patient in a real scene and registered in real time. The location of the lesion, an operation plan and the like can be displayed in an operation area in real time during the operation process, so that the sight and the area of concern of a surgeon are concentrated on the operation area, the repeated switching between the operation area and a navigation computer display is avoided, the reliability of operation and the accuracy of navigation are improved effectively, the tedious step for frequent change of an operation tool to a navigation probe by the surgeon in the traditional navigation during operation is avoided, the continuity of the operation is improved, and the operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of virtual reality imaging, in particular to an MR-based surgical navigation system and its equipment, method and storage medium. Background technique [0002] The existing computer-aided navigation system for surgery is a three-dimensional positioning operation support system, which provides relatively objective and accurate means for surgeons to plan operations, and can perform operation positioning according to the needs of actual operations. The tissue surrounding the tool is displayed accordingly, enabling real-time navigation of the surgery. However, the positioning of the navigation probe on the patient and the plane display of the position information on the computer monitor bring unintuitive and non-in-situ shortcomings, and limit the accuracy of the navigation surgery, prolong the time of the navigation surgery, and increase the risk of navigation. Difficulty of use. [0003] Mixed reality projec...
