WebNov 4, 2024 · In this study, a co-training loss is defined to promote accurate dynamic MR image reconstruction in a self-supervised manner. The main idea of the co-training loss is to enforce the consistency not only between the reconstruction results and the original undersampled k-space data, but also between two network predictions. WebApr 12, 2024 · Objective This study combines a deep image prior with low-rank subspace modeling to enable real-time (free-breathing and ungated) functional cardiac imaging on a commercial 0.55 T scanner. Materials and methods The proposed low-rank deep image prior (LR-DIP) uses two u-nets to generate spatial and temporal basis functions that are …

In dynamic MRI, we usually formulate the image as a matrix instead of a vector. Each column of the image matrix represents a vectorized temporal frame. The L+S algorithm decomposes the image matrix X as a superposition of the background component L and the dynamic …
WebJul 22, 2024 · Dynamic magnetic resonance imaging (MRI) exhibits high correlations in k-space and time. In order to accelerate the dynamic MR imaging and to exploit k-t correlations from highly undersampled data, here we propose a novel deep learning based approach for dynamic MR image reconstruction, termed k-t NEXT (k-t NEtwork with X … WebAbstract. Inspired by recent advances in deep learning, we propose a framework for reconstructing dynamic sequences of 2-D cardiac magnetic resonance (MR) images from undersampled data using a deep cascade of convolutional neural networks (CNNs) to accelerate the data acquisition process. In particular, we address the case where data …
