New Shared LoRA Framework Enhances MRI Reconstruction Efficiency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel parameter-efficient framework called Shared LoRA for magnetic resonance imaging (MRI) reconstruction. This method freezes a pretrained SHFormer backbone and trains a single set of LoRA adapters along with a gating network. By generating undersampled inputs across various acceleration factors during training, the shared adapters learn to reconstruct images effectively, while a gating network dynamically adjusts adapter strengths based on the given acceleration factor. Experiments demonstrate that Shared LoRA achieves competitive performance with significantly fewer trainable parameters, showing stable generalization to unseen factors. AI

IMPACT This method could lead to more efficient and cost-effective MRI reconstruction techniques by reducing the need for factor-specific models.

    One Shared LoRA Weight for MRI Reconstruction across Acceleration Factors

    arXiv:2609.06338v1 Announce Type: cross Abstract: Accelerated MRI reconstruction recovers images from undersampled k-space. However, different acceleration factors produce distinct artifact patterns. Existing methods often train separate models for each factor, leading to poor cr…
