Semantics-First Latent Modeling for 3D MRI Reconstruction
A new framework prioritizes anatomical semantics during 3D MRI latent compression, addressing long-range coherence and clinical detail loss. It introduces a Latent Harmonization Encoder and Semantic Recovery Block to preserve meaningful structures, and an Anatomy-aware Frequency Loss to maintain high-frequency diagnostic features. Experiments on public MRI datasets show improved reconstruction and cross-contrast synthesis quality.
