WebIn general, the fluoroscopy employed significantly lesser kVp (kilo-voltage peak) settings and mA (milli-ampere) while still giving reasonably good images of all long bones having diagnostic importance. In the fluoroscopy, the kVp factors ranged from 45 to 55 with low mA values of 1.2 to 1.7. WebFluoroscopy is a type of imaging procedure that uses several pulses of an X-ray beam to take real-time footage of tissues inside your body. Healthcare providers use fluoroscopy …
Webmilliamperes (mA). Fluoroscopy is usually performed using 2 to 6 milliamperes (mA) and an accelerating voltage of 75 to 125 kVp. The amount of x-rays produced by an x-ray tube is determined by the tube current (mA) and the high voltage (kVp). X-ray production is directly proportional to the tube current and doubling the
