Abstract
The present invention is a high-resolution magnetic resonance fingerprinting method based on radio frequency encoding, a device and storage medium, where radio frequency encoding is introduced into MRF, n time evolution signals can be collected by designing and respectively scanning a set of n radio frequency pulse signals, separate time evolution signals representing n sub-slices can be obtained after decoding and calculating according to a encoding process, and then separate quantitative images of the n sub-slices can be obtained through dictionary matching. Compared with conventional MRF, a slice resolution of the quantitative images obtained in the imaging method of the present invention is increased by n times and a signal-to-noise ratio is not reduced. Through a phantom experiment and a human experiment, accuracy of quantitative effect and an effective improvement of the resolution of the present invention are proved, and the present invention can provide higher-resolution quantitative imaging results.
