The original MRF method uses one spiral interleaf acquired
within each time point to reconstruct one image, leading to dramatic
fluctuation in the signal evolution caused by undersampling error. In this
work, a sliding window is utilized to select multiple interleaves to generate
one full-sampled image for each step so
that the fluctuation in signal evolution could be significantly alleviated. Therefore
our proposed method can reach an expected result with reduced time points. The results demonstrate that the proposed method can reduce the
acquisition time from about 11s to 5.6s or even less.
