RAD Exam 1 Questions with Complete
and Correct Answers
1. Vacuum (tube housing)
2. Source of electrons (filament)
3. Method to accelerate the electrons (voltage) rapidly
4. Method to stop the electrons (target) - Answer-What are the 4 elements needed to produce x-rays?
Primary Radiation, Remnant Radiation, Scatter Radiation - Answer-What are the three main types of
radiation?
Primary Radiation - Answer-X-ray beam after it leaves the tube and before it reaches the patient
Remnant Radiation - Answer-Radiation resulting after the x-ray beam exits the patient
Scatter Radiation - Answer-Radiation produced from x-ray photons interaction with matter in such a
way that the resulting photons have continued in a different direction
Carry NO useful diagnostic information
Image Receptor (IR) - Answer-Medium used to capture the image for recording, such as x-ray film or a
digital imaging plate
, Film/screen systems
Digital radiography cassette & cassetteless
Fluoroscopy - Answer-What are the types of IR (how they have changed)?
Photon - Answer-Quantum or particle of radiant energy
They are produced When electrons strike the target
Heat
Less than 1% of this production is actually x-rays, the remaining 99% is heat!!! - Answer-When x-ray
photons are produced, the majority of the energy is what?
kVp
mA
Time - Answer-What are the three technical factors set by the technologist that control image quality?
kVp - Answer-The quality of the primary beam (Controls the penetrating ability of the beam)
Determines the energy level of the primary beam
