A sonographer adjusts the output of an ultrasound transducer by increasing the amplitude by a factor of 3. Which of the following statements is true?

Ultrasound Energy used in diagnostic imaging is a longitudinal wave.

What is the attenuation coefficient in soft tissue if the frequency is 10 MHz?

What is the name for a region of low particle density and low pressure?

Higher frequency transducers have:

Spatial peak intensity refers to the peak value in time.

The thickness of the matching layer is:

What occurs if two waves of different frequencies combine?

These parameters are determined only by the sound source:

With a 5 MHz transducer the sound wave is traveling through a medium at a speed of 1500 m/s.  The depth is decreased from 8 cm to 4 cm.  What happens to the frequency?
