1. A method for performing magnetic resonance fingerprinting (MRF), the method comprising:
(a) obtaining, using a magnetic resonance scanning device, a first scan data of a sample at a low-resolution and of a first region in k-space;
(b) obtaining, using a magnetic resonance scanning device, a second scan data of a sample at a high-resolution and of a second region in the k-space;
repeating (a) and/or (b) according to a scanning ratio between the first scan data and the second scan data to generate interleaved low-resolution and high-resolution scan data; and
from the interleaved low-resolution and high-resolution scan data, generating high-resolution tissue property maps of the sample.
