Abstract
Producing radiographs of the best possible quality is the responsibility of every radiologic technologist. Many factors affect the finished radiograph, yet the effect of kilovoltage and milliamperage on a selected focal-spot size is almost always overlooked. With the selection of appropriate milliamperes and kilovolts, one can maintain high radiographic quality, reduce radiation absorbed dose to the patient, and prolong equipment life. Supporting data based on laboratory research are provided.
