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/). The core component of the software system is 3D Slicer, running on a Linux-based workstation, that 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 100 Base-T Ethernet to exchange data and commands using an open network communication protocol, OpenIGTLink. We developed a software module in 3D Slicer that offers all features uniquely required for MR-guided robotic prostate intervention, as follows: 1) management of the ‘workphase’ of the all components in the system; 2) treatment planning by placing target points on the pre-operative 3D images loaded on the 3D Slicer and robot control based on the plan; 3) registration of the robot and patient coordinate systems; 4) integrated visualization of real-time 2D image, preoperative 3D image, and visualization of the current needle position on the 3D viewer of 3D Slicer.
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.
