Objective

Improve the DICOM - DWI conversion mechanism in Slicer to support more scanners and file output formats.

Specific goals

1. Working with the PREDICT and HDNI longitudinal data sets as sample multi-site, multi-scanner test data corpus, add support for more scanning protocols and software versions.
2. General code clean-up -- DicomToNrrd had been repeatedly modified over the past few years by multiple authors, to the point where there is many instances of 'dead' code (never executed) and confusing paths of execution.

Approach, Plan

1. Approach
   1. Begin with original DicomToNrrd code.
   2. Analyze source code to capture the implicit knowledge about DWI DICOM data sets.
   3. Refactor code to straighten out program logic and remove obsolete and incorrect code.
2. Plan
   1. Incrementally refactor and improve C++ code
   2. Use regression tests, and tests against large collections of DICOM data sets to validate code
   3. Incorporate program into BRAINSTools suite (hosted at github) to facilitate inclusion in Slicer.
   4. Work with Slicer community to come up with new 'problem' datasets for testing.
