A perfect kilovolt (kV) waveform should generate the selected kV from:

A perfect kilovolt (kV) waveform should maintain a stable and consistent output throughout the entire duration of the exposure. This means that from the start to the end of the exposure, the voltage should be able to deliver the selected kilovolt level continuously. This stability is crucial because the energy of the X-ray photons produced is directly related to the kilovolt setting; any fluctuations or variations in the kV output can lead to inconsistent image quality or insufficient penetration ability of the X-rays.

Maintaining the selected kV from the beginning to the end allows for uniform exposure across the imaging area, which ensures that the image is of high quality and that the desired diagnostic information is accurately represented. A stable kV waveform is essential for producing reliable and reproducible radiographs.
