X RAY MACHINE QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT RATED A+
||UPDATED 2026/2027
Why is it important to understand how an X-ray machine works?
✔✔ Answer:
To identify faulty equipment
To know when repairs are needed
To communicate effectively with repair technicians
To work in equipment sales or technical support
To prepare for licensing and board examinations such as AVMA and
national boards
What is a conventional X-ray unit?
✔✔ Answer: A large radiographic unit that allows a wide range of exposure
settings
What is a mobile X-ray unit?
✔✔ Answer: A portable unit typically capable of settings up to 100–300 mA and
120 kVp
What is a mounted X-ray unit?
✔✔ Answer: A fixed unit that may have output capacities up to 1000 mA
What is a small portable X-ray unit?
✔✔ Answer: A lightweight, transportable unit usually limited to about 20 mA and
90 kVp, often requiring longer exposure times
, What are the five elements required for X-ray production?
✔✔ Answer:
Source of electrons (cathode)
Means of accelerating electrons
Free path for high-speed electrons (vacuum and kVp)
Target for electron interaction (anode)
Containment area with a vacuum tube
Cathode -ANSWER ✔✔Provides source of electrons
filament in cathode heated- exciting electrons
Energy in circuit is mA
Tungsten
Heated cloud of electrons formed
Acceleration is KV
Anode -ANSWER ✔✔Bombarded with electrons from cathode
Stationary anode -ANSWER ✔✔in dental and small portable units
small xray production
cannot stand large amounts of heat
bombarded with electrons
limit of 100 mA
Rotating anode -ANSWER ✔✔shape of a disc in center of tube
