Figure 14From: Proposition and evaluation of a collision detection method for real time surgery simulation of opening a brain fissureSimulation of opening the Sylvian brain fissure. (a) Overview of the simulation. Operator manipulates two spatula models with haptic devices. (b) Initial view of the Sylvian fissures. (c) The spatula models exposed the insula of the brain model. (d) Initial view from another angle. The depths of brain are not seen. (e) A part of the skull base is exposed.Back to article page
