Quick Start

This gives a brief quick start - introduction on how to download public datasets such as the Calgary-Campinas and FastMRI multi-coil MRI data and train models implemented in DIRECT.

1. Downloading and Preparing MRI datasets

The Multi-coil Calgary-Campinas dataset can be obtained following the instructions in the Calgary Campinas website and the FastMRI dataset can be obtained from the FastMRI website by filling in their form. Data should be arranged into training and validation folders. The testing set is not strictly required, and definitely not during training, if you do not want to compute the test set results.

Note: Preferably use a fast drive, for instance an SSD to store these files to make sure to get the maximal performance.

2. Install DIRECT

Follow the instructions in installation in the docs.

3. Training and Inference

3.1 Preparing a configuration file

To run experiments a configuration file must be created. For a sample configuration file please refer to config in the docs.

3.2 Projects

In the projects folder folder you can find examples of baseline configurations for our experiments.

Instructions on how to train a model or perform inference can be found in training in the docs.
