Abstract

This paper presents an implementation of stereo vision techniques to capture the geometric model of patient´s face for registration in the frameless neurosurgery. A distance transform is applied on 2D CT/MRI multi-slices for on-site registration, further reducing requisite computation. In order to validate accuracy of the system, we designed a phantom to directly measure its target registration error (TRE). Experimental results show that the TRE is 2.72 ± 0.735 mm.
