MATI (Microstructural Analysis of Tissues by Imaging) v1.0 is a GPU-accelerated toolbox for microstructural diffusion MRI simulation and data fitting with a user-friendly graphical user interface. MATI runs a Finite Difference simulation to simulate diffusion MRI signals arising from arbitrary modeled microstructural tissues and diffusion pulse sequences. As a general framework for data fitting, MATI fits any user-customized signal model to experimental data to extract parameters with a selection of fitting methods.
MATI was developed by Dr. Junzhong Xu at Vanderbilt University Medical Center. Please send your comments or questions to Junzhong (JZ) Xu (junzhong.xu@vanderbilt.edu)
MATI is distributed as a MATLAB App. It contains the following files:
- MATI.mlappinstall is the installation file.
- MATI_Guide.pdf is a quick guide about how to use MATI for simulation and data fitting with GUI screenshots.
- Examples.zip can be extracted to an Example folder that contains example code and data showing how to use MATI scripts. It can be downloaded from the release v1.0.
- LICENSE.md is the license file.
