The overall goal of this proposal is to develop and validate an integrated system based on open source software for improved visualization and probe placement during radiofrequency ablation (RFA) of liver tumors. While radiofrequency ablation is becoming an increasingly important treatment option for unresectable hepatocellular carcinoma (HCC) and liver metastases, the procedure has several technical limitations. These limitations are mostly related to the difficulty of precisely placing the RFA needle to ablate the entire tumor and achieve adequate margins. In particular, larger tumors require multiple overlapping needle placements, which can be difficult to achieve. The specific aims of the project are to: 1) Develop an open source software architecture for a liver RFA planning/treatment workstation that builds on existing open source projects at the two collaborating institutions 2) Develop and evaluate semi-automatic segmentation techniques for the liver, liver vasculature, and liver tumors. These techniques will be integrated with a graphical user interface and the segmentation results will be evaluated by comparison with expert radiologists. 3) Based on the segmented liver data set, develop a path planning module for evaluating alternative paths to the liver tumor and incorporating multiple overlapping placements as needed. 4) Integrate the two capabilities developed above along with electromagnetic tracking of the RFA probe to provide a complete software environment for liver tumor planning, visualization, and execution. This software environment will merge ongoing work at Georgetown and Brigham and Women's Hospital in developing open source software for image-guided procedures. 5) Validate the clinical feasibility of the system in a swine animal model. Agar nodules will be created in the swine liver and the ability of the system to segment and provide path planning for these nodules will be assessed. The accuracy of the system will also be evaluated. This research is important in advancing the technology for treatment of liver cancer that presently can not be treated well with current available therapies. This technology would also enable a modern, individualized therapy, which relies on integration of high power computers and innovations in medical science. It would have a contribution to public health by developing liver cancer treatments without the need for more invasive surgeries.

Objective

IGSTK provides connectivity with various kinds of tracking devices. However, IGSTK does not support communication with tracking devices over the network. The objective of this project is to establish Slicer-IGSTK connection through standard network to provides extensible and versatile way of configuration in image guided therapy.

Approach, Plan

We will design and implement a module to communicate with 3D slicer as a class of IGSTK. It connects to Tracker_Daemon through TCP/IP and controls MRML scene (tracker and real-time image).

Progress

Jan 2008 Project Half Week

We completed following tasks:

  • The bi-directional socket communication has been established between the Tracker Daemon in Slicer 3 and IGSTK Server which acquires tracking data from device and sends it to Tracker Daemon.
  • Real-time image transfer function is implemented using Slicer Daemon mechanism.
  • OpenIGTLink Protocol has been designed, and partially implemented in OpenIGTLinkDaemon Module in Slicer 3.

June 2007 Project Week

During the June 2007 Project Week, we designed communication framework for MRI-robot for Transperineum Prostate Brachytherapy (BRP Project/ PI: Dr. Clare Tempany), based on vtkIGTOpenTrackerStream.

Jan 2007 Project Half Week

Noby and Haiying developed the vtkIGTOpenTrackerStream class, which gives connectivity with NaviTrack data stream to the Slicer. This class shares a base class with vtkIGTIGSTKStream.
