This work presents a novel, practical imaging scheme for the rotating coil by using radial trajectories. A single channel pneumatically-driven rotating coil is built for 9.4 T preclinical system. We show in theory that with proper combination of rotation speed and sequence TR, the averaging effect of radial trajectories can be employed to minimise the effects of the rotation-dependent sensitivity on image formation. Preliminary experiments show that when radial ultra-short TE (UTE) sequence is combined with the rotating scheme, the single element rotating coil is capable of reconstructing images free of artefacts and intensity variation without using sensitivity calibration.
