Module Description

The OpenIGTLink Interface Module is a program module for network communication with external software / hardware using OpenIGTLink protocol. The module provides following features:

• Data import: The module can import position, linear transform and image data from OpenIGTLink-compliant software to the MRML scene.
• Data export: The module can export linear transform and image data from the MRML scene to external software.
• Multi-connection: The module can manage multiple OpenIGTLink connections at the same time.
• Locator visualization: The user can choose one of linear transforms in the MRML scene to visualize its position and orientation in the 3D space.
• Slice driving: The module can control volume re-slicing plane based on linear transform in the MRML scene.

Figure 1. The figure shows an example schematic diagram where multiple devices are communicating with 3D Slicer through the OpenIGTLink Interface. Each connector is assigned to one of the external devices for TCP/IP connection. The connectors serve as interfaces between the external devices and the MRML scene to convert an OpenIGTLink message to a MRML node or vice versa.
