This is an open source repository that supplies diffusion-MRI data with tensor-valued diffusion encoding. Data is available in a healthy human brain in vivo as well as water, oil and liquid crystal phantoms. The repository also contains detailed information and resources concerning the experiment and its design.
Value of the data:
- The data facilities design and testing of analysis techniques that require tensor-valued (or multidimensional) diffusion encoding. This provides value since acquisition of such data currently relies on a custom pulse sequence that is not widely available.
- The data includes repeated sampling of spherical b-tensors for analysis of noise characteristics.
- A subset of the data is matched with respect to the diffusion time spectrum for analysis of models of diffusion time dependency.
