DOI: 10.1016/j.mri.2019.05.008

Abstract: Diffusion magnetic resonance images typically suffer from spatial distortions due to susceptibility induced off-resonance fields, which may affect the geometric fidelity of the reconstructed volume and cause mismatches with anatomical images. State-of-the art susceptibility correction… read more here.

Published in 2021 at "Applied optics"

DOI: 10.1364/ao.428465

Abstract: In order to improve the wavefront distortion correction performance of the classical stochastic parallel gradient descent (SPGD) algorithm, an optimized algorithm based on Nesterov-accelerated adaptive momentum estimation is proposed. It adopts a modified second-order momentum… read more here.

Published in 2020 at "PLoS ONE"

DOI: 10.1371/journal.pone.0236418

Abstract: Diffusion magnetic resonance images may suffer from geometric distortions due to susceptibility induced off resonance fields, which cause geometric mismatch with anatomical images and ultimately affect subsequent quantification of microstructural or connectivity indices. State-of-the art… read more here.
