Real-Time Mapping of Tissue Properties for Magnetic Resonance Fingerprinting

no code implementations16 Jul 2021 Yilin Liu, Yong Chen, Pew-Thian Yap

Magnetic resonance Fingerprinting (MRF) is a relatively new multi-parametric quantitative imaging method that involves a two-step process: (i) reconstructing a series of time frames from highly-undersampled non-Cartesian spiral k-space data and (ii) pattern matching using the time frames to infer tissue properties (e. g., T1 and T2 relaxation times).
