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.
The datasets can be utilized for studying real-time MRI reconstruction techniques. By loading the .mat-files, the measured k-space data, sampling trajectory, coil sensitivity maps, and estimated cardiac phase and cycle are available as described in the documentation.
