Abstract

The invention provides a surface-based intraoperative registration method. The method comprises the steps as follows: receiving patient face three-dimensional point cloud information sent by a three-dimensional scanner; receiving a position matrix sent by optical tracking equipment, wherein the position matrix is the position matrix of the three-dimensional scanner in a space coordinate system ofthe optical tracking equipment in the patient face scanning process; performing initial registration on the patient face three-dimensional point cloud information and CT (computed tomography) data ofthe face of a patient before operation to obtain an initial transfer matrix from the CT data to the real space coordinate system where the patient is located; determining a transfer matrix from the three-dimensional scanner to the coordinate system of the optical tracking equipment; determining a target transfer matrix according to the position matrix, the initial transfer matrix and the transfermatrix; transferring the CT data to the real space coordinate system where the patient is located on the basis of the target transfer matrix. The invention also discloses neuronavigation equipment. Bymeans of the surface-based intraoperative registration method and the neuronavigation equipment, the intraoperative registration accuracy and the intraoperative registration can be improved.

Description

technical field [0001] The invention relates to the field of surgical navigation, in particular to a surface-based intraoperative registration method and neuronavigation equipment. Background technique [0002] Surgical navigation refers to accurately corresponding the patient's preoperative or intraoperative image data with the patient's anatomical structure on the operating bed, tracking the surgical instruments during the operation, and updating and displaying the position of the surgical instruments on the patient image in real time in the form of a virtual probe. Intraoperative registration is a very important link in the surgical navigation system, and the accuracy of intraoperative registration directly affects the accuracy of surgical navigation. Intraoperative registration is mainly the process of converting the virtual world coordinate system of the patient's computerized tomography (CT) and other medical images into the real world coordinate system of the patient....
