FLUOROSCOPY

Question 1

List 4 types of fluoroscopic image acquisition modes. (4 marks)

Answer 1

1 mark: Continuous fluoroscopy.
1 mark: Pulsed fluoroscopy.
1 mark: High-dose acquisitions.
1 mark: Single high-dose image.

Question 2

Name 2 design features that reduce anode heating during fluoroscopy. (2 marks)

Answer 2

1 mark: Oil or liquid cooling of the anode.
1 mark: High-speed anode rotation to distribute heat.

Question 3

A student radiographer is undergoing clinical placement in fluoroscopy and has been using both mobile and fixed fluoroscopic systems. List 3 advantages of mobile fluoroscopic systems and 3 advantages of fixed fluoroscopic systems. (6 marks)

Answer 3

Mobile Systems
1 mark Can be moved between theatres.
1 mark Does not require a custom room design.
1 mark Can be replaced mid-procedure without moving the patient.

Fixed Systems
1 mark More reliable X-ray generators.
1 mark Usually has more features.
1 mark Often provides better radiation protection.

Question 4

Explain how fluoroscopic imaging differs from conventional radiography. (2 marks)

Answer 4

1 mark: Fluoroscopy provides real-time dynamic imaging, while conventional radiography captures static images.

1 mark: Fluoroscopy uses continuous or pulsed X-ray beams to create moving images, whereas conventional radiography uses a single exposure.
