CCI physics exam questions with correct
answers 2026-2027
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)
Where is the region where the best resolution can be obtained? - CORRECT ANSWER -focal zone
Will widening the sector width decrease or increase the frame rate? - CORRECT ANSWER -decrease
is the smallest to largest group of intensities which produce a shade of gray. -
CORRECT ANSWER -dynamic range
What is PRF dependent on? - CORRECT ANSWER -depth
does deeper imaging cause a lower or higher prf? - CORRECT ANSWER -lower prf
What is the Nyquist limit? - CORRECT ANSWER -
The highest Doppler frequency or velocity that can be measured without the appearance of aliasing (eq
uals 1/2 of the PRF)
What is FFT? -RCORRECT ANSWER -Fast Fourier Transform
Most adult echocardiography is performed with frequencies of .... - CORRECT ANSWER -2.0 to 5.0MHz
