Which of the following is typically assessed during acceptance testing of an ultrasound transducer?

• A. Frequency response
• B. Battery life
• C. Wireless interference
• D. Color balance

Answer: (A)

Acceptance testing checks that the transducer performs to its defined specifications before it’s released. The crucial metric here is the frequency response, which describes the transducer’s ability to emit and receive signals at its intended frequencies and across its bandwidth. This determines image quality: a probe with the correct center frequency and a specified bandwidth provides good axial resolution and adequate penetration for the target exams. Measuring the frequency response ensures the probe will deliver the expected performance in practice.

Other aspects like battery life are relevant only for portable or wireless units, wireless interference is a system-level concern, and color balance relates to display or image processing, not the transducer’s electrical/mechanical performance.
