Objective

Transform Recorder: We are developing a Slicer4 module that receives the tracking data of multiple tools through an OpenIGTLink connection. The incoming tracking data is recorded and stored in xml files. The trajectory analysis the Transform Recorder module provides will be useful information for new surgical navigation methods.
Other modules: As time allows, we will work on other modules needed for US-guided interventions.

Approach, Plan

The PLUS (Public Library for Ultrasound) library sends OpenIGTLink messages to Slicer. The user interface sets up the tracked transforms for different tools. A custom number of annotation messages would also be made possible for the user to add messages to the recoding. The incoming tracked transforms are used to update surgical tools in the scene.

Progress

Transform Recorder has been ported to Slicer 4 from Slicer 3. Started development on another IGT module called Target Fiducials. The loadable module observes a fiducial list and a needle transform. When the needle comes close to a fiducial, it should hide it as if a bubble was popped. This would be useful for tracked needle demos.
