This paper addresses the problem of Magnetic Resonance (MR) imaging of moving targets using spiral scan echo planar data collection. A system model is developed to interpret the readouts of repeated spiral excitations via two separate time variables, the slow-time and fast-time. This mathematical model is used to construct an inversion for forming the time progression of the target image. A method for increasing the repetition rate of the spiral data collection is presented. Results are provided.
