In many ultrafast imaging applications, the reduced field-of-view(r FOV) technique is often used to enhance the spatial resolution and field inhomogeneity immunity of the images. The stationary-phase characteristic of the spatiotemporallyencoded(SPEN) method offers an inherent applicability to r FOV imaging. In this study, a flexible r FOV imaging method is presented and the superiority of the SPEN approach in r FOV imaging is demonstrated. The proposed method is validated with phantom and in vivo rat exper...

1.IntroductionThe last decades have witnessed a continuous growthin the use of single-shot MRI,both for clinical and re-search applications.[1–8]Owing to the good temporal resolu-tion,these single-shot MRI methods are referred to as“ultra-fast”imaging
