Abstract
With increasing capability and complexity of surgical interventions,
intra-operative visualization is becoming an important part of a surgical
environment. This paper reviews some of our recent progress in the
intelligent use of pre- and intra-operative data for enhanced surgical
navigation and motion compensated visualization. High fidelity augmented
reality (AR) with enhanced 3D depth perception is proposed to provide
effective surgical guidance. To cater for large scale tissue deformation,
real-time depth recovery based on stereo disparity and eye gaze tracking is
introduced. This allows the development of motion compensated visualization
for improved visual perception and for facilitating motion adaptive AR
displays. The discussion of the paper is focused on how to ensure perceptual
fidelity of AR and the need for real-time tissue deformation recovery and
modeling, as well as the importance of incorporating human perceptual
factors in surgical displays.
