Abstract

An augmented reality system has been developed and is currently under evaluation to document changes induced by surgical correction of a spine deformity. A pre-operative measurement technique is developed that permits the matching between a patient and a virtual 3-D medical image of normally hidden anatomy. The matching algorithm tested on a phantom gives a RMS error of respectively 1.1 mm and 2.0 mm with 1.0 and 2.0 mm random noises added to the measured points
