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.
