Merlin Plus: Tumor Masks and Tumor Detection And Segmentation Models

[PedroRASB]

Adds:

• Merlin Plus (dataset, MICCAI 2026): over 1,100 radiologist-created tumor masks covering 9 tumor types, AI-generated masks for 44 organs, and longitudinal metadata (patient IDs and scan dates) for the Merlin dataset.
• Merlin-Super (model): R-Super trained on Merlin Plus reports and masks; our best-performing model for cancer detection and segmentation.
• Merlin-Cancer-Net (model): nnU-Net trained on Merlin Plus tumor masks.
