Abstract

Here we exploit the off-resonance profile of the steady-state free precession (SSFP) sequence to encode spatial information with ultra-low flip angle radiofrequency pulses, enabling a super-resolution reconstruction from a rapid series of low-resolution images. This opens up new possibilities for rapid, high-resolution and low specific absorption rate (SAR) SSFP imaging, particularly at ultra-high magnetic field strengths.
