LGE CMR SAX Phantom Images and Segmentation Masks

Synthetic imaging data used for analysis of Radiomic feature comparability Phantom (synthetic) images of a single short-axis cardiovascular MRI slice of the heart (showing only the left ventricular myocardium and bloodpool), and corresponding segmentation masks in nifti format for whole myocardium and 17-segment AHA model. The phantom exists at a range of sizes (myocardial diameter between 28 and 99mm) and a range of resolutions (between 0.6 and 2.2mm isotropic voxel-size), as well as at resolutions corresponding to voxel-densities between 28 and 76 voxels per myocardial diameter. LGE patterns have been added to the healthy myocardium: global mesocardial LGE, global subendocardial LGE, global subepicardial LGE, inferolateral transmural LGE, and a patchy pattern. In each case, extent of LGE is 30% of the entire myocardium.
