KMAR-50K
KMAR-50K is a paired knee MRI dataset developed for motion-artifact removal. Each pair contains an MRI sequence affected by motion and a corresponding ground-truth sequence obtained by rescanning the same patient.
The KMAR-50K data are publicly available from Mendeley Data under the Creative Commons Attribution 4.0 International license (CC BY 4.0), which permits commercial reuse with attribution.
The dataset contains 1,444 paired MRI sequences from 1,190 patients and 62,506 slices. It includes coronal, sagittal and transverse scans acquired at 1.5 T and 3.0 T, radiologist image-quality scores and both processed and unprocessed anonymized NIfTI data. The collection is split across two linked Mendeley repositories.
