This code relates to the publication ssVERDICT: Self-Supervised VERDICT-MRI for Enhanced Prostate Tumour Characterisation by Snigdha Sen et al.
A preprint is available at: https://arxiv.org/abs/2309.06268
This code fits the Vascular, Extracellular and Restricted DIffusion for Cytometry in Tumours (VERDICT)-MRI model for prostate using self-supervised deep learning, adapted from https://github.com/sebbarb/deep_ivim.
There are four files included: main.py, verdict_data.py, train.py and base_model.py.
- Edit main.py and verdict_data.py to contain the corect file path to load the data you want to fit the VERDICT model to, as well as the mask you want to use.
- base_model.py contains the formulation of the complex VERDICT signal compartments in differentiable form.
- train.py contains the training protocol.
- Run main.py to fit the model to your data.
