D120 Week 3 Questions with 100% Correct
Answers
What are the 3 main parts of the imaging system?
Generator, control panel, xray tube
What is in the X-ray tube?
Glass envelope, cathode and rotating anode
What is the anode composed of?
tungsten and rhenium
What is the inefficiency of X-ray in the diagnostic range?
-60 kVP, only 0.5%
-100 kVp only 1%
What is the inefficiency of X-ray in the therapeutic range?
20 mv, 70%
What is Bremsstrahlung radiation?
Bremsstrahlung x-rays are produced when a projectile electron is slowed by the electric field
of a target atom nucleus.
What is characteristic radiation?
An electron interacts with an inner-shell electron of the target, knocking it out of orbit. Outer
shell electrons fill the vacancy and as this happens energy is released as an xray photon.
What does characteristic radiation require in regards to energy?
