摘要： A hip resurfacing CAS system for guiding an operator in altering a femoral head in computer-assisted surgery for subsequent implanting of a femoral head implant, comprises a trackable reference on the femur. A registration tool is trackable. A bone-altering tool is associated with a resurfacing of the femoral head. A tracking apparatus tracks the tools. A resurfacing processing unit is connected to the tracking apparatus so as to receive tracking data for the tools. The resurfacing processing unit has a position/orientation calculator to calculate from the tracking data a position and orientation of the trackable reference to track the femoral frame of reference, and of the registration tool and the bone-altering tool. A model generator receives position and orientation data of the registration tool to produce a model of the femoral head and neck with respect to the femoral frame of reference. A resurfacing evaluator determines an evaluated bone resurfacing alteration as a function of a position and/or orientation of the bone-altering tool with respect to the bone model of the femoral head and neck, and a tool geometry model, at least prior to resurfacing being performed.

摘要： The described method for determining at least orientation of a pelvic bone in space and for tracking movement of the pelvic bone using a computer assisted surgery (CAS) system includes removably attaching, in a non-invasive manner, at least one reference marker, in communication with the CAS system, to a skin surface covering the pelvic bone. Registering at least orientation readings of the reference marker is then performed with respect to a fixed reference in a reference coordinate system, following which at least an orientation of the pelvic bone in the reference coordinate system is determined using the orientation readings of the reference marker. These steps are repeated to update the orientation readings while tracking the pelvic bone in space.

摘要： A system tracks an object in computer-assisted surgery. The system comprises a sensor unit secured to the femur. Gyroscopes on the sensor unit produce readings related to orientation data about three axes of rotation. A tracking unit receives the gyroscope readings. An axis calibrator on the tracking unit comprises a calculator for adding at least part of the gyroscope readings for specific movements of the object about a desired axis. An axis normalizer on the tracking unit determines an orientation of the desired axis with respect to the sensor unit from the added gyroscope readings. A tracking processor tracks the desired axis from the gyroscope readings. An interface displays orientation data for the object from a tracking of the desired axis. A method for tracking an object with a gyroscope sensor unit is also provided.
