Keywords: Machine Learning/Artificial Intelligence, Quantitative Imaging, Multitasking
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.
