LRA 211 Radiology Image Final exam
part 2 (Goodluck)
The protective tube housing helps to - ✔✔ correct answer -Keep the tube cool.
-prevent electrical shocks to the radiographer.
-limit leakage radiation.
By regulation, x-ray tube leakage radiation can be no more than: - ✔✔ correct answer 100 mR/hour
@ 1 meter
The primary purpose of the glass or metal enclosure is to - ✔✔ correct answer maintain a vacuum
within the tube.
The target window is usually approximately - ✔✔ correct answer 5 cm^2
The rotating anode design uses a disc whose core is made of - ✔✔ correct answer molybdenum
Tungsten is used to coat the anode disc because it has. - ✔✔ correct answer a high atomic number
The portion of the induction motor that is outside the tube enclosure is the - ✔✔ correct answer
stator
the process of a series of outer-shell electrons filling inner-shell vacancies is known as - ✔✔ correct
answer characteristic cascade
Bremsstrahlung interactions may occur only when the incident electron interacts with - ✔✔ correct
answer the force field around the nucleus.
The energy of the brems photon depends on the - ✔✔ correct answer -energy of the filament
electron as leaves the tungsten atom
-strength of the attraction b/t the electron and the nucleus
-original energy of the filament electron
Which of the following radiographic factors will affect x-ray quantity? - ✔✔ correct answer -
Kilovoltage-peak (kVp)
