Haptic representation of non-invasive region for surgery based on volumetric data

Abstract

Micro surgery needs adequate navigation by using virtual reality technology. This paper proposes method of haptic representation of non-invasive area fo r support system of micro surgery. An operator of our system holds 6 DOF force display and sees volume graphics. In case the virtual treatment tool approaches non-invasive area, force is applied to the operator's hand in order not to invade the area. Generated force is determined by volume data of CT image. Through the evaluation of the basic performance of this method, we applied our algorithm to experiment of navigation in human gullet.
