Guidelines/Instructions
The selection of kVp sets the energy of the X-rays reaching the scanned object. Each object will in density and atomic number, both of which will impact the X-ray beam's attenuation. Larger, denser objects will require higher or more intense kVp selections to ensure a sufficient number of photons exit the object and are subsequently captured by the detector.
