Kilovoltage peak (kVp or kV) is the voltage applied between the cathode and anode of an x-ray machine. The kVp determines the maximum x-ray energy that will be produced and the spectrum of x-ray energies produced. kVp is commonly thought of as "speed of a car" or how fast the electrons will reach the target materiel (rotating anode).
