Top 10 Questions for CT Scan Technologist (Computed Tomography Scan Technologist) Interview

1. Explain the principles underlying computed tomography (CT) scanning?

• CT scanning uses X-rays to create cross-sectional images of the body.
• X-rays are passed through the body and the amount of radiation absorbed is detected by sensors.
• The data is then processed by a computer to create images of the body’s internal structures.

2. Describe the different types of CT scanners and their uses?

Single-slice CT scanners

• Produce images of a single slice of the body at a time.
• Used for simple scans, such as chest X-rays and head CTs.

Multi-slice CT scanners

• Produce images of multiple slices of the body at a time.
• Used for more complex scans, such as cardiac CTs and abdominal CTs.

Cone-beam CT scanners

• Produce 3D images of the body.
• Used for specialized scans, such as dental CTs and orthopedic CTs.

3. What are the radiation safety considerations for CT technologists?

• Limit exposure to radiation as much as possible.
• Use lead aprons and gloves to protect themselves from radiation.
• Monitor their radiation exposure levels regularly.

4. Describe the quality control procedures for CT scanners?

• Daily quality control checks
• Monthly quality control checks
• Annual quality control checks

5. What are the different imaging parameters that can be adjusted on a CT scanner?

• Slice thickness
• Field of view (FOV)
• Reconstruction algorithm
• Contrast agent

6. How do you communicate with patients during a CT scan?

• Explain the procedure to the patient.
• Answer any questions the patient may have.
• Reassure the patient throughout the procedure.

7. What are the different types of artifacts that can occur on CT images?

• Motion artifacts
• Beam hardening artifacts
• Ring artifacts
• Metal artifacts

8. How do you troubleshoot common CT scanner problems?

• Image quality problems
• Mechanical problems
• Electrical problems

9. What are the emerging trends in CT technology?

• 3D printing
• Artificial intelligence
• Virtual reality

10. What are your strengths and weaknesses as a CT technologist?

Strengths

• Strong technical skills
• Excellent communication skills
• Compassionate and patient

Weaknesses

• Can be stressed under pressure
• Not always good at delegating tasks
