Question: 1 / 400

A sonographer is performing a renal ultrasound. Which transducer frequency will generate the slowest speed of sound?

All frequencies will travel at the same speed in the same tissue.

In diagnostic medical sonography, the speed of sound in tissue is a universal constant and does not vary with the frequency of the ultrasound wave. This means that regardless of the transducer frequency used (2 MHz, 4.5 MHz, or 7 MHz), the speed of sound in tissue remains constant. As a result, all frequencies will travel at the same speed in the same tissue. Therefore, option A is the correct answer.

It is crucial to understand this concept in ultrasound imaging to accurately interpret the images produced by different transducer frequencies.
