Abstract
A method for surgical imaging and display including (i.) positioning a defined set of markers disposed in a pattern so as to be imaged in each pose or view of an imaging assembly, the set of markers being fixed in pre-determined positions in a rigid carrier, (ii.) securing a first tracking element against motion with respect to the rigid carrier so that determining a position of the first tracking element in a single measurement determines positions of all the markers of the set, and (iii.) identifying images of at least a subset of the markers in a first view.
