CCI physics exam questions with correct
answers 2025-2026
True or false. Increasing the depth results in a decrease in the pulse repetition frequency? -
CORRECT ANSWER -true, it will take longer for the pulse to travel back and fourth from transducer
What is the amplification of sound controlled by? - CORRECT ANSWER -gain or DCG/TCG
What is transmit power? - CORRECT ANSWER -
the voltage which is applied to the transducer itself, it controls the intensity of the sound beam (ALARA
- as low as reasonably acheiveable)
