Free-breathing 2D Cartesian Cardiac MRI Datasets

The dataset contains ungated free-breathing cardiac MRI scans with different image resolutions and slice thicknesses. Specifically, two low-resolution scans (2.27mm x 2.26mm resolution at 264 x 186 acquisition matrix size) are available with 10mm slice thickness and isotropic slice thickness, respectively, and a high-resolution scan (1.25mm x 1.26mm resolution at 480 x 334 acquisition matrix size) with 5mm slice thickness. The scans were taken of a single healthy volunteer using a 2D Cartesian partial-Fourier sampling pattern on a 3T Philips Elition X scanner and image a short-axis view of the beating heart. The raw k-space data, sampling trajectory, and coil sensitivity maps (estimated by the scanner) are provided, as well as the cardiac phase estimated by an electrocardiogram.
