Soft tissue deformation for surgical simulation: a position-based dynamics approach.

ABSTRACT:

Purpose

To assist the rehearsal and planning of robot-assisted partial nephrectomy, a real-time simulation platform is presented that allows surgeons to visualise and interact with rapidly constructed patient-specific biomechanical models of the anatomical regions of interest. Coupled to a framework for volumetric deformation, the platform furthermore simulates intracorporeal 2D ultrasound image acquisition, using preoperative imaging as the data source. This not only facilitates the planning of optimal transducer trajectories and viewpoints, but can also act as a validation context for manually operated freehand 3D acquisitions and reconstructions.

Methods

The simulation platform was implemented within the GPU-accelerated NVIDIA FleX position-based dynamics framework. In or
