From: Augmented reality navigation method for recontouring surgery of craniofacial fibrous dysplasia
The accuracy evaluation for the performance of the system: The pre-operative virtual plan and post-operative 3D craniomaxillofacial models were imported into 3D analysis software (Geomagic Control X, 3D Systems Inc., South Carolina, USA), and hundreds of pairs of points were generated uniformly in the surgical area. Each of the paired points was located along the normal vector of the skull surface. The distance between the paired points indicated the surgical discrepancy.
