Every Digital Radiography (DR) company provides a technique chart with their panels. These x-ray prescriptions have evolved over time from the days of film and as DR panels have evolved to be more sensitive. Most likely, the DR company has spent a good bit of time testing and optimizing these techniques to provide the best image quality for their panels. But what ARE these knobs (kVp and mAs) and what do they DO to your image quality for a variety of species and sized patients? And what are the implications on patient dose, personnel dose, and panel dose?
