Paper Abstract

We find that pulsed fluoroscopy of stationary objects gives average dose savings of 22 percent, 38 percent, and 49 percent 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 (HVS) describes these results with one free parameter. Pulsed-30 is always better than continuous for detecting moving objects. Likewise, pulsed-15 saves dose as compared to pulsed-30, but the savings decrease for high velocities and small objects.
