Sensible human projects: haptic modeling and surgical simulation based on measurements of practical patients with MR elastography--measurement of elastic modulus

Abstract

To provide realistic surgical simulation, 3D visualization and haptic feedback are important. In the existing surgical simulators, the fidelity of the deformation and haptic feedback is limited because they are based on the subjective evaluation of the expert-user and not on an objective model-based evaluation. To obtain accurate elastic modulus of whole human tissues, we have started a new project called the Sensible Human Project (SHP). This paper deals with establishing the measurement of elastic modulus by the magnetic resonance elastography (MRE) technique, as a first step of the SHP Project.
