Question

A sonographer is using a 3 MHz transducer and changes to a 6 MHz transducer. The imaging depth remains unchanged. Would each of the following parameters increase, decrease, or remain the same?

A. Period
B. Frequency
C. Wavelength
D. Speed
E. Intensity (initial)
F. PRF
G. Pulse Repetition Period

Answer 1

Changing from a 3 MHz to a 6 MHz transducer will decrease the period and wavelength, increase the frequency, and potentially increase the initial intensity while keeping the speed of sound constant. PRF and pulse repetition period may change depending on the settings.

Step-by-step explanation:

When a sonographer changes from a 3 MHz transducer to a 6 MHz transducer, various parameters related to the ultrasound wave will change. Here's how each parameter would be affected:The terms like frequency, wavelength, and period are vital for understanding ultrasonography. A sonographer must consider how these parameters affect the image quality and depth of penetration when selecting a transducer.
