Deep MRI Reconstruction with Radial Subsampling

1 code implementation17 Aug 2021 George Yiasemis, Chaoping Zhang, Clara I. Sánchez, Jan-Jakob Sonke, Jonas Teuwen

In spite of its extensive adaptation in almost every medical diagnostic and examinatorial application, Magnetic Resonance Imaging (MRI) is still a slow imaging modality which limits its use for dynamic imaging.

vSHARP: variable Splitting Half-quadratic ADMM algorithm for Reconstruction of inverse-Problems

no code implementations18 Sep 2023 George Yiasemis, Nikita Moriakov, Jan-Jakob Sonke, Jonas Teuwen

In this study, we propose vSHARP (variable Splitting Half-quadratic ADMM algorithm for Reconstruction of inverse Problems), a novel DL-based method for solving ill-posed inverse problems arising in MI.

Deep Cardiac MRI Reconstruction with ADMM

no code implementations10 Oct 2023 George Yiasemis, Nikita Moriakov, Jan-Jakob Sonke, Jonas Teuwen

In this work, inspired by related work in accelerated MRI reconstruction, we present a deep learning (DL)-based method for accelerated cine and multi-contrast reconstruction in the context of dynamic cardiac imaging.

JSSL: Joint Supervised and Self-supervised Learning for MRI Reconstruction

no code implementations27 Nov 2023 George Yiasemis, Nikita Moriakov, Clara I. Sánchez, Jan-Jakob Sonke, Jonas Teuwen

In this paper, we introduce JSSL (Joint Supervised and Self-supervised Learning), a novel training approach for deep learning-based MRI reconstruction algorithms aimed at enhancing reconstruction quality in scenarios where target dataset(s) containing fully sampled k-space measurements are unavailable.
