Shepp Logan Dataset#

Details#

The Shepp Logan Dataset is based on the implementation of the 3-dimensional Shepp Logan phantom as presented in [1]. More specifically, we use from [1] the ellipsoid and tissue parameters.

In DIRECT are implemented three different Shepp Logan datasets:

  • T1-weighted (SheppLoganT1Dataset)

  • T2-weighted (SheppLoganT2Dataset)

  • Proton density (SheppLoganT1Dataset)

The Shepp Logan Datasets allow for data-less testing of the MRI models.

Use the SheppLoganDataset#

Configuration#

A toy configuration file for training a Unet2d model can be found in NKI-AI/direct.

Training#

Since data are created on the fly, there is no need to pass to the command line training or validation directory paths. The following command might be used for training using the Shepp Logan Datasets:
