Recently, more and more attention is drawn to the field of medical image synthesis across modalities. Among them, the synthesis of computed tomography (CT) image from T1-weighted magnetic resonance (MR) image is of great importance, although the mapping between them is highly complex due to lar...
The 3D T1-weighted brain image inputs were first resampled into a grid of 256 × 256 × 256 voxels with an isotropic spatial resolution of 1 × 1 × 1 mm using the mri_convert routine in FreeSurfer33. From the resampled complete images, coronal slices around the MTL we...
