Brief Introduction:

This software package is developed for processing diffusion tensor imaging (DTI) data, under the auspice of National Institute of Biomedical Imaging and Bioengineering (NIBIB) and a grant from Shanghai Commission of Science and Technology.

 This software package is written in Python with Tkinter. The source code of the software tools and pieces integrated into this package were originally developed using C/C++, OpenGL, Matlab. Based on our work in the past years, the package covers the commonly used functions for DTI processing, including the following modules (Fig. 1):

1.       Converting imaging data in DICOME  format to ANALYZE format

2.       Extracting  binary brain mask for quick scalp-removing

3.       Correcting eddy-current induced distortion

4.       Optimized tensor estimation based on noisy diffusion-weighted imaging (DWI) data

5.       Scalp removal using a brain mask image

6.       Corregistering imaging data and generating deformation field for mapping images from individual spaces to a template or target space

7.       Spatial Normalization  and Warping DTI

8.       Fiber tracking

9.       Clustering fiber tracts

10.   Identifying brain ventricles and generating binary masks for the baseline and DW imaging data

11.   Deriving diffusion anisotropy indices (DAIs) and principal directions (PD) and the corresponding color-coded PD-map.

A Note:
   The above snapshots are based on the SUN Solaris version. The interfaces of the Linux Versions may show some misalignment, but will not affect the functionality and execution of the functions.
