I am trying to use the diffusion tractography capabilities of 3DSlicer to visualise some data I have collected from my PhD research. It is similar to diffusion weighted MRI but does not produce diffusion weighted images. My data is processed in such a way that I end up with vectors at various coordinates in 3D space (these vectors represent the directions of collagen fibre tracts).
Essentially what I would like to do is jump into the “diffusion mri analysis pipeline” so I start with a custom DTI volume in slicer. i.e. I would like to generate a custom version of slide 42/107 from: here .
My current approach has been to try and create a new volume following the process here but I cannot seem to find a way to input a custom tensor field. Does anyone know if this is possible or whether there is a better way of achieving what I’m trying to do?
Thank you, please let me know if anything needs clarifying,
