BRAINSDemonsWarp

Back to NA-MIC Brains Collaboration

Summary: BrainDemonsWarp is a command line program for image registration by using different methods including Thirion and diffeomorphic demons algorithms. The function takes in a template image and a target image along with other optional parameters and registers the template image onto the target image. The resultant deformation fields and metric values can be written to a file. The program uses the Insight Toolkit (www.ITK.org) for all the computations, and can operate on any of the image types supported by that library. This program is based on the Diffeomorphic Demons Using ITK's Finite Difference Solver Hierarchy work by Vercauteren et al. Some additional features have been added to the program that may enhance the resulting correspondence between datasets.

Progress:

1. Registration tool has been developed and is currently hosted on the NITRC website
2. Initial testing has been performed

To Do:

1. Complete documentation and Insight Journal article documenting the program
2. Extend the framework to support vector images allowing for multiple imaging modalities to be used to define the correspondence between subjects.
