From: SCreg: a registration-based platform to compare unicondylar knee arthroplasty SPECT/CT scans
Schematic representation of the registration platform workflow. Legend: All scans (grey) are first pre-processed (blue). The images obtained (orange) are then registered. Affine registration (green) is used to align intra-subjects scans and a combination of rigid (brown) and non-rigid (red) registration is used for inter-subjects scans alignments. Once aligned, SPECT is analyzed and intra- and inter-subjects comparisons are performed
