Summary

• What is new: Introduction of LHU-Net, a Light Hybrid U-Net architecture, achieving improved segmentation accuracy with reduced model complexity.
• Why this is important: Current hybrid models blending CNNs and Transformers in medical image segmentation suffer from high computational demand and overlook the interplay between spatial and channel features.
• What the research proposes: LHU-Net optimizes volumetric medical image segmentation by analyzing spatial features initially, then focusing on channel-based features, ensuring comprehensive feature extraction.
• Results: LHU-Net sets new performance benchmarks on five datasets, notably a Dice score of 92.66 on the ACDC dataset, with 85% fewer parameters and a quarter of the computational load compared to existing models.
