+MedSAM was trained on a large-scale medical image segmentation dataset of 1,090,486 medical image-mask pairs collected from different publicly available sources. 
 The image-mask pairs cover 15 different imaging modalities and over 30 cancer types.
 
 MedSAM was initialized with the pre-trained SAM model with the ViT-Base backbone. The prompt encoder weights were frozen, while the image encoder and mask decoder weights were updated during training.
