Joint Learning of Cartesian under Sampling Andre Construction for Accelerated MRI

ICASSP 2020accepted

Magnetic Resonance Imaging (MRI) is considered today the golden-standard modality for soft tissues. The long acquisition times, however, make it more prone to motion artifacts as well as contribute to the relative high costs of this examination. Over the years, multiple studies concentrated on desig…

The Learned Inexact Project Gradient Descent Algorithm

ICASSP 2018accepted

Accelerating iterative algorithms for solving inverse problems using neural networks have become a very popular strategy in the recent years. In this work, we propose a theoretical analysis that may provide an explanation for its success. Our theory relies on the usage of inexact projections with th…
