RAM-H1200
RAM-H1200 is a multicenter hand-radiograph dataset developed for comprehensive assessment of rheumatoid arthritis. It supports bone instance segmentation, pixel-level bone-erosion segmentation and joint-level Sharp/van der Heijde scoring.
The official repository provides the benchmark documentation and directs users to the associated dataset distribution. The image download currently requires authentication, and a clearly stated dataset license governing commercial reuse could not be independently verified. Commercial use is therefore recorded as unknown.
The dataset contains 1,200 hand radiographs collected from six medical centers. Its annotations include whole-hand bone instance masks, pixel-level bone-erosion masks, Sharp/van der Heijde joint regions and joint-level scores for bone erosion and joint-space narrowing. The publication does not report a clearly verifiable unique-patient count, so num_subjects is null. The exact downloadable image and annotation formats were not stated clearly enough in the accessible official metadata, so format is left empty rather than inferred. Hand is represented as 'other' because the current anatomy enum has no hand value.
