title: An Image-based Multiproxy Palpation Algorithm for Patient-Specific VR-Simulation.
abstract: Palpation is the first step for many medical interventions. To provide an immersive virtual training and planning environment, the palpation step has to be successfully modeled and simulated. Here, we present a multiproxy approach that calculates friction and surface resistance forces for multiple contact points on finger tips or virtual tools like ultrasound probes and displays the resulting force and torque on a 6DOF haptic device. No manual or time intensive segmentation of patient image data is needed to create a simulation based on CT data and thus our approach is usable for patient-specific simulation of palpation.
