WebX-ray tubes used in diagnostic X-ray exams all use the same physical principles including: thermionic emission (boiling off electrons), accelerating electrons by a kiloVoltage potential (kVp), and two physical interactions contribute to x-ray generation: bremstraalung (breaking radiation), and characteristic radiation (peaks in energy spectrum). WebThus, the kVp corresponds to the highest kinetic energy of the electrons striking the target, and is proportional to the maximum photon energy of the resulting X-ray emission spectrum.
