Bases: Dataset

M4Raw KData Dataset.

M4Raw [M4RAW] low-field (0.3T) brain dataset. The data can be downloaded from zenodo [M4RAW_DATA]. The data consists of Cartsian GRE, T1w, T2w, and FLAIR images with multiple repetitions. It will be returned as mrpro.data.KData objects of either a single slice or a stack of slices with multiple repetitions.
