METHOD AND SYSTEM FOR SPINE TRACKING IN COMPUTER-ASSISTED SURGERY

摘要

A method for spine tracking in computer-assisted surgery, the method includes: obtaining, at a computer-assisted surgical system, at least one image of at least part of the spine and at least one surgical device; determining, at the computer-assisted surgical system, a three-dimensional position and orientation of the at least one surgical device relative to the spine from the at least one image to create a referential system; tracking, at the computer-assisted surgical system, the at least one surgical device altering a first vertebra of the spine for attachment of a spinal screw to the first vertebra, in the referential system; and tracking, at the computer-assisted surgical system, the spine in the referential system with a trackable reference attached to the spinal screw of the first vertebra.
