Identify and explain
A transducer sends and receives acoustic signals; processed echoes generate an image.
- Patient-contact footprint
- Transducer body
- Cable and scanner connection
Principle
Frequency, penetration and resolution are related.
Safety
Use clinically appropriate examinations and validated cleaning procedures.
At the viva table
Try answering aloud, then open the suggested answer. Examiner questions vary.
01 / Does ultrasound use ionising radiation?
No. It uses acoustic energy.
02 / Are all probes interchangeable?
No. Geometry and frequency range suit different applications.
03 / Why does orientation matter?
It links the displayed image to the patient’s anatomy.
04 / Does no ionising radiation mean unlimited non-medical use?
No. Ultrasound should still be used appropriately and with prudent exposure.
