A Virtual Reality Simulator for Ultrasound-Guided Biopsy Training

A VR-based training system for practicing biopsies simulates ultrasound imagery by stitching multiple ultrasound volumes on the basis of a 3D scale-invariant feature transform algorithm. In addition, a six-degree-of-freedom force model delivers a realistic haptic rendering of needle insertion.
