English(EN) Variational Network with Wavelet-based UNET in Accelerated MRI Reconstruction from Under Sampled K-space Data

新型MRI重建技术采用Wavelet-UNet提升细节表现

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种新颖的变分网络，其中包含基于小波的U-Net（W-UNet），用于加速MRI重建。该方法通过用离散小波变换和逆小波变换模块替换标准的池化操作，增强了欠采样k空间数据的重建。这种方法同时保留了低频结构和高频边缘细节，从而提高了伪影抑制和特征保留能力。在fastMRI膝部和M4Raw脑部数据集上的实验证明了该方法达到了最先进的性能，验证了基于小波分解在加速MRI中的有效性。 AI
