研究人员开发了两个新颖的框架来提高磁共振成像（MRI）的质量。PhyMRI-SR将MRI超分辨率视为一个物理感知的重建问题，改编了2D高斯溅射法，并融入了关于解剖结构和成像系统的先验知识。UniField则提供了一个统一的框架，用于多场强MRI增强，利用3D体积信息和场感知频谱校正机制来提高跨不同场强的泛化能力。这两种方法都旨在提高MRI的诊断可及性和研究能力。

Magnetic resonance imaging (MRI) super-resolution is vital for improving diagnostic accessibility, yet most methods treat it as a deterministic mapping from a fixed low-resolution input to a high-resolution target. This overlooks a key property of MRI acquisition physics: spatial…
MR super-resolution is reformulated as a physics-aware reconstruction problem that dynamically adapts resolution-SNR configurations using Gaussian splatting with prior-aware representations and physics-constrained modeling.

arXiv:2607.07581v1 Announce Type: new Abstract: Clinical cardiac MRI is commonly acquired with high in-plane resolution but coarse through-plane resolution to reduce scan time and accommodate breath-hold and cardiac-motion constraints, which limits 3D analysis and diagnostic accu…
Clinical cardiac MRI is commonly acquired with high in-plane resolution but coarse through-plane resolution to reduce scan time and accommodate breath-hold and cardiac-motion constraints, which limits 3D analysis and diagnostic accuracy. We propose STRMSR, a reference- and memory…
