Top 10 Questions for X-ray Service Engineer Interview

1. What are the primary components of an X-ray system?

The primary components of an X-ray system include:

• X-ray tube
• High-voltage generator
• X-ray collimator
• X-ray detector (either film-screen or digital)
• Control console

2. How does an X-ray tube generate X-rays?

Thermionic Emission

• A high-voltage current heats the cathode, causing electrons to be emitted (thermionic emission).
• The electrons are then accelerated towards the anode target.

Collision and Bremsstrahlung

• When the accelerated electrons collide with the anode target, their negative charge is attracted to the positively charged nucleus of the anode atoms.
• Most of the electron’s energy is converted into heat, but a small percentage is released as X-rays (bremsstrahlung).

Characteristic Radiation

• The electrons may also knock electrons out of the anode atoms, creating vacancies in the inner electron shells.
• When outer-shell electrons drop down to fill these vacancies, X-rays are emitted with specific energies characteristic of the anode material.

3. Explain the purpose and function of a collimator in an X-ray system.

• To define the shape and size of the X-ray beam
• To reduce scattered radiation
• To improve image quality
• To reduce patient dose

4. Describe the different types of X-ray detectors and their advantages and disadvantages.

Film-Screen Cassettes

• Advantages: relatively inexpensive, widely available
• Disadvantages: time-consuming to process, require chemicals, limited dynamic range

Digital Detectors

• Advantages: faster, higher dynamic range, no chemicals required
• Disadvantages: more expensive, not as widely available

5. Explain the role of the control console in an X-ray system.

• Controls the operating parameters of the X-ray system
• Sets the exposure factors (kVp, mAs)
• Monitors the system’s performance
• Provides a user interface for the operator

6. What are the common causes of X-ray image artifacts and how can they be corrected?

Motion Artifacts

• Cause: Patient or equipment movement during exposure
• Correction: Use immobilization devices, reduce exposure time

Scattered Radiation

• Cause: X-rays scattering from surrounding structures
• Correction: Use collimators, grids

Beam Hardening

• Cause: Lower-energy X-rays being preferentially absorbed by the patient
• Correction: Use filters, adjust kVp

7. Describe the basic principles of troubleshooting an X-ray system.

• Gather information about the problem (symptoms, error messages)
• Review the system’s operating manual
• Perform a visual inspection of the system (cables, connections, components)
• Use diagnostic tools (multimeters, oscilloscopes)
• Consult with technical support

8. What are the safety precautions that must be taken when working with X-ray equipment?

Radiation Protection

• Use lead aprons, gloves, thyroid shields
• Maintain a safe distance from the X-ray source

Electrical Safety

• Follow proper grounding and wiring procedures
• Do not operate equipment with frayed cables or loose connections

General Safety

• Never leave the X-ray beam unattended
• Keep the work area clear of unnecessary objects
• Follow all manufacturer’s instructions and guidelines

9. What is your experience with maintaining and repairing X-ray equipment?

I have over [number] years of experience maintaining and repairing X-ray equipment. I am familiar with the common problems that can occur and have the skills and knowledge to diagnose and fix them quickly and efficiently.

10. How would you stay up-to-date on the latest advances in X-ray technology?

• Attend industry conferences and seminars
• Read technical journals and articles
• Participate in online forums and discussion groups
• Consult with manufacturers and other experts in the field
