about dTV
Overview
The diffusion TENSOR Visualizer (dTV) is an extension program developed for the volume data viewer program VOLUME-ONE . dTV performs analysis of DTI data and transfers results to VOLUME-ONE for display. Several new features are added in dTV.II including pararell fiber tracking with multi-thread computation.
Main Feature
- Compatible for 6 - 255 directions of motion probing gradient (*1) with multiple b-values
- Three analysis modes: Fiber tracking / Diffusion profile display (incl. ellipsoid) / Voxel statistics
- ROI editors
- Creating computational data such as FA ,map, color-coded FA map, ADC map, DKI map
- DKI computation models
(*1) You may need to import MPG vectors of your imaging protocol.

- Yoshitaka MASUTANI, PhD, Ph.D, Professor in Hiroshima City University

FAQ
Q1. May I redistribute dTV?
A1. Sorry. We do not allow that.
Q2. May I make a link on my webpage to the webpage of dTV?
A2. We accept links only on academic/research sites. But, contact us in advance.
Q3. I can not load my DICOM data
A3. Make raw (plain) format of the volume data, then import it on VOLUME-ONE, and start dTV.
Q4. I imported MPG data correctly, but analysis results seem strange.
A4. Check coordinate system of your MPG data. Imported MPG data must be in VOLUME-ONE coordinate system. In some cases already reported, MPG vectors are described in MR scanner coorinates or Z element is inverted. Rotate or flip MPG data in such cases.
Q5. I have a question about VOLUME-ONE ...
A5. See FAQ page and/or refer quick reference of VOLUME-ONE website.
Manuals
These are for older versions but useful (sorry... in Japanese).
