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

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

  2. 2 MHz

  3. 4.5 MHz

  4. 7 MHz

The correct answer is: 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.
