RTE 1401 Practice Test 2 Questions and Answers |
2026 Update | 100% Correct.
what elements are required to produce an XR photon?
1. X- ray tube
2. Technical Factors (kVp, mA)
3. Vacuum
4. Great potential differences between cathode and anode
What is a vacuum important?
Avoids any collision of any other particles and allows the electrons to have a faster passage
What does it mean to have a great potential difference?
Between positive and negative. Electrons are more concentrated on one side
Where are XR actually produced?
Anode disk, actual focus spot
How fast do electrons travel?
half the speed of light
How fast do things with NO matter move?
At the speed of light
Tube Current
flow of electrons from cathode to anode
, What increases the tube current?
mA, milliamperage
Two ways to produce XR photons
1. Bremsstrahlung
2. Characteristics
brems- means
stop, braking, slowdown, deceleration the radiation
-strahlung means
radiation
Bremsstrahlung
radiation that is produced when the electrons are slow down braking decelerated and stop at the
target
What is the bremsstrahlung target?
the actual focus spot
How does Bremsstrahlung radiation work?
when high speed electrons lose a great amount of its initial energy at this target, so energy of the
XR photon produced is exactly the "DIFFERENCE" between the incident electrons and the
exiting energy of the electron
Electrons get repelled from an atom during bremsstralung by __________ _________
