Objective

We are developing a Slicer4 module that can receive tracked ultrasound images through an OpenIGTLink connection, and create a representation of the real-time ultrasound image in the Slicer scene.

Approach, Plan

The PLUS (Public Library for Ultrasound) library will send OpenIGTLink messages to Slicer. Images to update the ultrasound image data, and transforms to update the ultrasound slice position and other surgical tools in the scene.

Progress

Software for the fiber tracking and statistical analysis along the tracts has been implemented. The statistical methods for diffusion tensors are implemented as ITK code as part of the DTI Software Infrastructure project. The methods have been validated on a repeated scan of a healthy individual. This work has been published as a conference paper (MICCAI 2005) and a journal version (MEDIA 2006). Our recent IPMI 2007 paper includes a nonparametric regression method for analyzing data along a fiber tract.
