Immunity to field perturbation, spatial resolution and signal-to-noise ratio (SNR) are three significant factors needed to concern in MRI. Recently, a spatiotemporally encoded (SPEN) imaging approach based on linear frequency-swept excitation has been proposed to overcome the artifacts induced by various field perturbations. To demonstrate the superiority of SPEN imaging approach in reduced field of view (rFOV) imaging, a flexible rFOV imaging approach is proposed in this paper. Experiments on phantom and in vivo rat brain show that the flexible rFOV scheme can produce images with higher SNR and spatial resolution. Meanwhile, the regions of interest can be flexibly imaged.
