OpenIGTLink

Overview

Integration of transperineal prostate robot (BRP -- Brigham and Women's Hospital/Johns Hopkins University/Queen's University/Acoustic Med Systems

The Open IGT Link protocol is a simple but extensible data format to transfer various types of data among software and devices used in image-guided therapy (IGT) scene e.g. surgical navigation software, tracking device, robotic device, imaging scanner. The protocol can handle image, tracking data, transform, device control and monitoring command, and other user-defined data types. It is designed to work in the application layer of the TCP/IP stack, but not limited to it; developers can use this protocol with UDP/IP or other network protocol models. 3D Slicer' supports Open IGT Link and has interface module as OpenIGTLinkIF, which is currently available in 3D Slicer ver. 3.4 and 3.5.

This is a generalization of the previous Tracker Daemon.

Protocol

We are currently drafting formats of new message types, which will potentially be included in OpenIGTLink version 2. The new version will be backward compatible with version 1, in the sense that all messages generated by software with version 1 interfaces can be imported by those with version 2 interfaces.

Version 1

• Standard Protocol
• Site and Project Specific Extended Protocols
  • MRI robot project at Johns Hopkins University, Baltimore, MD
  • Transrectal Ultrasound-guided biopsy, Johns Hopkins University, Baltimore, MD
  • MRI real-time Imaging acquisition and control, Brigham and Women's Hospital, Boston, MA

Version 2 (in draft)

• Protocol description (draft)
  • (Discussions for version 2)
