Question Number 133

The transducer you are using transmits wide-bandwidth pulses whose frequency content is 2-5MHz. Which of the following most correctly describes the reflected echo signals after they have traversed the tissue?

A: The echo signals will be shifted down in frequency due to the increased attenuation of higher frequencies.

B: The echo signals will be of reduced intensity but will have the same frequency content as the transmitted beam.

C: The echo signals will be shifted upward in frequency due to the increased absorption of the lower frequencies.

D: Only the center frequency component of the bandwidth will be reflected back to the transducer.

E: The echo signal frequency content will be identical to that of the transmitted beam.

✔ Correct Answer:

A: The echo signals will be shifted down in frequency due to the increased attenuation of higher frequencies.
