Researchers have developed a new framework called Multiple Prototype Contrastive Learning (MPCL) to improve semi-supervised medical image segmentation. This method addresses the challenge of intra-class heterogeneity in medical images, where the same anatomical structure can have varying intensity patterns. MPCL utilizes Intensity-aligned Heterogeneous Prototype Generation to create multiple prototypes that capture this diversity, followed by Prototypical Space Optimization to refine these representations. Finally, Dual-branch Knowledge Alignment facilitates the transfer of this heterogeneous knowledge to the segmentation network, leading to more precise results, especially with limited labeled data.
