SHFormer 通过动态频谱滤波和 Transformer 增强 MRI 重建

研究人员开发了 SHFormer,这是一种用于自适应磁共振成像 (MRI) 重建的新型神经网络架构。该模型利用动态频谱滤波卷积神经网络 (CNN) 和高通核生成 Transformer 来改进高频细节的捕获,而这些细节通常会被现有的基于注意力(attention-based)的模型所忽略。SHFormer 旨在提供高质量的重建和跨不同 MRI 数据域的可重用特征,在未见过(unseen)的场景中显示出峰值信噪比 (PSNR) 和结构相似性度量 (SSIM) 的显著改进。 AI

影响 为自适应 MRI 重建引入了一种新架构,有可能提高图像质量和跨域数据的可重用性。
