Objective
Integration of SPECTRE Skull Stripping software into the NAMIC Toolkit via the Slicer3 CLI framework.
Approach, Plan
Our approach: integration of software which will segment and provide coordinate reference frames for the Cerebrum (akin to the Talairach space), the Cerebellum (see reference below for K. Rehm), and for the Brainstem.
This will be achieved through integration of the Java Imaging Software Toolkit (JIST) into the Slicer3 framework and then testing and evaluation of JIST components for completing the necessary components to provide this system.
The main challenge is supporting Java command line executables in 3D Slicer.
Our plan is first to facilitate Java command line module discovery and execution, by adding support for the --xml argument to SPECTRE, and adding support for tcl wrapping scripts in 3DSlicer. Then integrate SPECTRE into the NAMIC toolkit by crafing a CMakeLists.txt file to allow it to be built easily. Create a NITRC project and a 3D Slicer extension that can be either downloaded or built on any platform.
Progress
A proof of concept sample Java HelloWorld application has been added to 3D Slicer.
Changes to the Command Line Module logic and Module Factory were made to support launching the tcl script with tclsh, for cross platform compatibility.
Changes made to the Java classes to support the --xml argument, Slicer recognises SPECTRE as a command line module.
Reading in the output images from SPECTRE back into Slicer works, to do: volume origin and win/level, stderr issue.
Presentations
Powerpoint presentation given by Jerry L. Prince on the status of the integration of SPECTRE as a module within Slicer, given at the 2010 Winter AHM in Utah.
