Kilovoltage Peak (kVp) - Video Lesson

Hey, everybody. Welcome back. This lesson is about KVP, one of the prime exposure factors. KVP is actually an acronym that stands for kilo voltage peak. The KVP is what accelerates electrons and forces them through the x-ray tube. During an x-ray exposure, the cathode is negatively charged, and the anode is positively charged. This difference in charge is called the two potential or potential difference. We measure the two potential in units of kilovolts. That's why this technical factor is called the kilo voltage peak. The KVP describes the maximum voltage difference between the cathode and anode during the x-ray exposure. This voltage difference is very important because this is what forces the electrons to move across the x-ray tube. The electrons at the cathode are negatively charged
