Abstract :
The authors find that pulsed fluoroscopy of stationary objects gives average dose savings of 22%, 38%, and 49% at 15, 10 and 7.5 acq/sec, respectively. Dose savings depend on object size, with less savings for smaller objects. A model that includes the spatio-temporal response of the human visual system describes these results with one free parameter
