SO-Mamba advances MRI reconstruction with state-space model

Researchers have developed SO-Mamba, a novel state-space model designed for accelerated MRI reconstruction. This model improves upon existing methods by differentiating between persistent reconstruction evidence and update-dependent information within its processing stages. SO-Mamba utilizes a State-Ownership Router to manage this evidence, leading to enhanced accuracy and anatomical coherence in MRI scans. Experiments on multiple public benchmarks demonstrate SO-Mamba's superior performance compared to CNN, Transformer, and standard Mamba-based approaches, while maintaining efficient computation. AI
