Objective
We are developing a tool for preparing diffusion weighted and diffusion tensor image data.
Details of the tool functionality were discussed between UNC and Utah:
- "Protocol" based execution
- Parameter files contain all settings
- Handles conversion of DICOM data to volumetric formats (NRRD)
- Automated quality control, corrects/rejects, provides reporting facility.
- Motion correction
- Eddy current correction
- Interpolation of data
- Rejection of interslice brightness
- Local plausibility check with reconstructed DTI
- FA/MD histogram comparison with atlas
- Local dot product of principal direction with atlas
- Full brain tracking for flips/permutations of axes
- Focus QC on white matter only
- DTI data, as well as FA/MD
Approach, Plan
The tool will allow a "protocol" based execution via parameter files. The parameter files contain all the settings/preferences/options and this file can be created using the tool's GUI. This tool will handle the conversion of DICOM data to volumetric image formats (NRRD), perform automated quality control, correct data if possible, possibly reject parts of the data and provide a reporting facility.
