Deep subspace unrolling network for accelerating non-Cartesian sampled CMR Multitasking imaging

Key Points

The proposed unrolling network achieves iterative reconstruction significantly faster than traditional methods, reducing imaging time dramatically.
Imaging time was reduced from 71 minutes to just 5 minutes using a GPU, enhancing CMR multitasking efficiency.
Deep subspace unrolling network with Unet density compensation accelerates convergence in CMR imaging processes.
This approach has potential clinical applications due to its ability to maintain reconstruction accuracy despite reduced imaging times.

Abstract

Motivation: The prolonged imaging time of CMR Multitasking limits its clinical application. Goal(s): Developing deep learning method to improve the imaging speed while ensuring the reconstruction and quantification accuracy. Approach: Developing a deep subspace unrolling network with an Unet as density compensation to accelerate convergence. Results: The proposed unrolling network achieved the iterative reconstruction in 5 iterations. Impact: The proposed method reduces the imaging time of CMR multitasking from 71 minutes (MATLAB) to 5 minutes (GPU), providing possible clinical applications.
