To reduce scan time, methods to accelerate hybrid phase encoded/non-Cartesian MR fingerprinting (MRF) acquisitions for variable density spiral acquisitions have recently been developed. These methods are not applicable to MRF acquisitions wherein a single k-space spoke is acquired per frame. Therefore, we describe, implement, and test a low-rank inversion method on a 0.35T MR-guided radiation therapy system to resolve MR fingerprinting contrast dynamics from through-plane accelerated Cartesian/radial measurements.
