The best specifications for superior pulsed fluoro rates would be those that gave a wide range of pulse rate selections. Ideally, rates should exceed 8 pps because that is the rate at which an image starts to appear continuous to the naked eye. There are significant differences in pulse rates between various C-arms.
For vascular, cardiac, bolus chase application 15 and 30 pps rates are used to acquire cine. These applications are almost always options to standard C-arms.
