Volumetric real-time MR raw data of porcine model during right heart catheterization

Raw stack-of-spirals data of gadolinium-filled balloon catheterization of a porcine model in the ISMRMRD file format. Four scans are included: prescan-reference.h5 and prescan-reference_noise.h5, which contains fully sampled stack-of-spirals data and an associated noise reference scan. 3drt.h5 and 3drt_noise.h5, which contain real-time MRI during catheterization and an associated noise reference scan.
