Question

Why is frequency important in diagnostic sonography?

A) It affects the amplitude of sound waves.
B) It determines the speed of sound in tissue.
C) It influences the depth of penetration.
D) It is irrelevant in diagnostic sonography.

Answer 1

Frequency is important in diagnostic sonography because it affects the depth of penetration, the speed of sound in tissue, and the amplitude of sound waves.

Step-by-step explanation:

In diagnostic sonography, frequency is important for several reasons:

1. It affects the depth of penetration. Lower frequencies penetrate deeper into the body, allowing for imaging of organs and tissues located deeper within.
2. It influences the speed of sound in tissue. Different tissues have different speeds of sound, and the frequency of the ultrasound waves used can affect how accurately images are captured.
3. It is used to determine the amplitude of sound waves. The amplitude of sound determines the intensity or loudness of the wave, which can impact the quality of the images produced.
