Background
Low signal‐to‐noise ratio (SNR) has been a major limiting factor for the application of higher‐resolution diffusion‐weighted imaging (DWI). Most of the conventional denoising models suffer from the drawbacks of shallow feature extraction and hand‐crafted parameter tuning. Although multiple studies have shown the promising applications of image denoising using convolutional neural networks...
In diffusion weighted echo planar imaging, eddy current distortion is a common reason for deformation of diffusion weighted imaging, which will affect the calculation result of diffusion tensors. A global ICC-based correction method is proposed for the eddy current distortion of the MRI weighted images, which combines the CSF-Mask-ICC registration with a global error correction. It can eliminate the...
