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 1):
A surgical navigation system comprising:\n a head-worn display device, to be worn by a user during a surgical procedure, comprising a processor unit, a display generator, a sensor suite having at least one tracking camera or depth sensor wherein: the processing unit creates a reference surface map of an exposed surface of an anatomical object with data received from the sensor suite; the processing unit establishes a reference frame relative to the sensor suite for the reference surface map; orientation of the reference frame is established by creating additional surface maps of other anatomical features of the anatomical object; the processing unit tracks a pose of the anatomical object relative to the head-worn display device by (i) creating a displaced surface map of the exposed surface and (ii) rotating and translating the displaced surface map and reference frame to achieve a best fit to the reference surface map.
