Abstract:
The present invention provides a mixed reality surgical navigation system ( 10 ) to be worn by a user ( 106 ) during a surgical procedure comprising: a display device ( 104 ), to be worn by a user ( 106 ) during a surgical procedure, comprising a processor unit ( 102 ), a display generator ( 204 ), a sensor suite ( 210 ) having at least one camera ( 206 ) or depth sensor wherein the processing unit ( 102 ) creates a reference surface map ( 5804 ) of an exposed surface ( 5806 ) of an anatomical object ( 4204 ) with data received from the sensor suite ( 210 ); the processing unit ( 102 ) establishes a reference frame ( 5810 ) relative to the sensor suite ( 210 ) for the reference surface map ( 5804 ); orientation of the reference frame ( 5810 ) is established by creating additional surface maps ( 5834 ) of other anatomical features ( 5824 ) of the anatomical object ( 4204 ); the processing unit ( 102 ) tracks a pose of the anatomical object ( 4204 ) relative to the system ( 10 ) by creating a displaced surface map ( 5814 ) of the exposed surface ( 5806 ) and rotating and translating the displaced surface map ( 5814 ) and reference frame ( 5810 ) to achieve a best fit to the reference surface map ( 5804 ) .

Claim (Index 10):
The method of  claim 9  further comprising:\n Creating a surface map of a replaced femoral head; and \n change in the femoral head is measured by comparing the surface map of the replaced femoral head and at least one of the additional surface maps of the femoral head.
