CalgarySliceTransform

class deepinv.datasets.CalgarySliceTransform(mask_generator=None, seed_mask_generator=True, estimate_coil_maps=False, acs=None, espirit_crop=0.95, prewhiten=False, normalize=False)

Bases: MRISliceTransform

Extract params and estimate coil maps for Calgary raw data.

To be used with deepinv.datasets.CalgarySliceDataset.

Note

The test set comes already masked, so this transform estimates the mask from the zeros of y. For the validation set, the data is fully-sampled, so the estimated mask will be all-ones.

Examples using CalgarySliceTransform:
