High‐Resolution Diffusion‐Weighted Imaging With Self‐Gated Self‐Supervised Unrolled Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose High‐resolution diffusion‐weighted imaging (DWI) is clinically demanding. The purpose of this work is to develop an efficient self‐supervised algorithm unrolling technique for submillimeter‐resolution DWI. Methods We developed submillimeter DWI acquisition utilizing multi‐band multi‐shot EPI with diffusion shift encoding.

Improved SNR Estimation Algorithm

2017 International Conference on Computer Systems, Electronics and Control (ICCSEC), 2017
As for several NDA SNR estimation algorithm for QPSK signal, their SNR estimation performance is poor. This article puts forward an improved low complexity SNR estimation algorithm to improve the SNR estimation range and accuracy. The mean, bias and variance of the new algorithm are simulated.
