CLINICAL MEDICINE

Detailed explanation-1: -The total filtration permanently mounted in the useful beam shall not be less than: 0.5 mm aluminum equivalent for machines operating up to 50 kilovolts peak (kVp), 1.5mm aluminum equivalent for machines operating between 50-70 kVp, and. 2.5 mm aluminum equivalent for machines operating above 70 kVp.

Detailed explanation-2: -The correct kilovoltage setting will range between 60-‐70 kV. Remember, if you select the correct kV, you will take images that have good density and contrast while using less radiation. This reduces patient and operator exposure to radiation.

Detailed explanation-3: -* If the exposure is always between 50 and 70 kVp: Total Filtration (inherent plus added) must equal 1.5 mm of aluminum equivalent. * If the exposure is always over 70 kVp: Total Filtration (inherent plus added) must equal 2.5 mm of aluminum equivalent.
