Objective: To provide the infrastructure necessary to represent, manage, and transform between the variety of coordinate frames used in medical imaging.


Progress: A new image class, itk::OrientedImage, has been developed and added to ITK. This image class caches the image direction cosines. ITK's IO mechanisms have been updated to read and write orientation information. Filters which implictly manipulate orientation (flip, resample, etc.) have been modified to explictly modify the cached image orientation.
