Question

Explain the kVp 15% rule

Answer 1

ANS) The kVp 15% rule says that altering the kilovolt peak( kVp) by 15 percentage have the identical consequence as doubling the milliampere-second( mAs) or lowering the milliampere-second by fifty percentage.

The enhancement in the kilovolt peak by 15 percentage creates a reduction in milliampere-seconds by 1/2.

A reduction in kilovolt peak by 15 percentage leads to the doubling of milliampere-second.

* The main 3 motives to utilize 15% rule are as follows;

1) Reduction of scatter

2) Reduction of the client dose.

3) Lessen time period or damage and destruction in tube.

At the time of utilizing the 15% law,we will be deciding the beam quantity.That means the overall amount of x-ray photon of beam.
