What is the photoelectric effect? - ANSWER-Incoming energy is an x-ray photon interacting with an atom in the body rather than an electron interacting with the tungsten anode.
What is the compton effect? - ANSWER-occurs at energy levels of 40-125 kVp . The incoming x-ray interacts with an OUTER orbital electron of an atom and removed it from the atom the goes in a different direction.
Ion - ANSWER-when a neutral atom gains or loses an electron
Bremmstrahlung radiation - ANSWER-One of two types of x- rays. Brems is created when an electron enters the tungsten anode of the x-ray tube and misses the tungsten electrons and gets near the nucleus. The electron suddenly slows down and deviates. The loss of energy creates an x-ray photon.
Remnant radiation - ANSWER-What remains of the primary beam after it has been attenuated by matter. Remnant radiation creates the x-ray image.
