Objective

We will perform a mock-up procedure to validate our software / hardware system for MRI-guided transperineal prostate intervention.

Approach, Plan

The software system consists of three sub-components: a) control software for the needle placement robot, b) software to control a closed-bore whole body 3T MRI scanner (GE Excite HD 3T, GE Healthcare), and c) open-source surgical navigation software (3D Slicer, http://www.slicer.org/) and RadVision (AcousticMed Systems). The navigation software serves as an integrated environment for calibration, surgical planning, image guidance and device monitoring and control. The 3D Slicer communicates with the other components through Ethernet to exchange data and commands using an open network communication protocol, OpenIGTLink.

Progress

During IGT Workshop in 2008 (Boston, December 2008), we successfully tested communication among the navigation software (3D Slicer / RadVision), robot control software, and 3T MRI at BWH. Since then, we have been working primarily on two tasks: improvement of the pneumatic mechanism at JHU and volunteer studies to analyze the workspace in the 3T MRI at BWH.
