Abstract

The invention belongs to the field of medical devices, and in particular relates to a registration method and system for three-dimensional orthopedic surgery navigation; the technical problem to be solved is: to provide a registration method for three-dimensional orthopedic surgery navigation with simple and convenient operation and fast registration speed Registration method and system; the technical solution adopted is: a registration method for three-dimensional orthopedic surgery navigation, including the steps of: collecting image coordinates of landmark points on the phantom; Conversion relationship between coordinates; acquisition of the spatial trajectory of the C-arm; according to the conversion relationship between the spatial trajectory of the C-arm and the spatial coordinates of the marker points on the phantom before surgery, and the collected spatial trajectory of the C-arm , calculate the spatial coordinates of the marker points on the phantom; register the image coordinates of the marker points on the phantom with the spatial coordinates of the marker points on the phantom; it is applicable to the field of medical devices.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a registration method and system for three-dimensional orthopedic surgery navigation. Background technique [0002] The three-dimensional orthopedic surgical navigation system is more and more widely used in clinical practice because of its ability to observe the position of surgical instruments in real time during surgery. The spatial coordinate system is established with the positioning system as the data source, and the transformation from the spatial coordinate system to the image coordinate system is realized by calculating the conversion relationship between the two coordinate systems, that is, registration, so as to achieve the purpose of real-time tracking and acquisition of surgical instruments during surgery. [0003] Registration is an essential and key step in the use of 3D orthopedic surgery navigation. The traditional registration method is mostly completed by pasting...
