Cardiac super-resolution label maps
NIfTI files in end diastole (ED) and end systole (ES) at low resolution (LR) and high resolution (HR) in 1,331 subjects. Ground truth labels for the left ventricular blood pool, left ventricular myocardium, and right ventricular blood pool at LR and HR were produced as previously described (https://doi.org/10.1016/j.media.2015.08.009).
Steps to reproduce
A dataset of 1331 healthy adults was collected. High-spatial resolution 3D balanced steady-state free precession cine sequences were used that assessed the left and right ventricles in their entirety in a single breath-hold (60 sections, reconstructed voxel size 1.2 x 1.2 x 2 mm, 20 cardiac phases, typical breath-hold 20s). Conventional single slice multi-breath-hold images were also acquired in the same geometry (10 sections, reconstructed voxel size 1.8 x 1.8 x 8 mm). Imaging was performed on a 1.5-T Philips Achieva system (Best, the Netherlands).
