Rad Tech 265

Rad Tech 265. More Digital Imaging. Digital Fluoroscopy. Radiation dose Patient dose for DF is significantly less than conventional fluoro At 7.5 pulses/second DF has a 75% drop in exposure At 3 pulses/sec a 90% reduction in dose The lower dose is obviously advantageous for pediatric work.
