Which form of attenuation is due to the sound wave not continuing on the path that the ultrasound unit thinks it's going? Amplitude Absorption Reflection Refraction

All of the following are assumptions that the ultrasound unit makes EXCEPT: All interfaces are encountered at an oblique angle. Ultrasound travels in a straight path. Ultrasound waves are traveling through tissue at 1.54 mm/µs. The sonographer made proper adjustments.

Sound is attenuated as it travels through a medium. Which of these factors affects the degree by which sound is attenuated? Select all that apply. Marks are deducted for incorrect responses.Group of answer choicesThe frequency of the soundThe medium the sound is transmitted throughThe polarisation of the sound waveInitial amplitude of the soundThe distance over which the sound travels

Adjusting which control on the ultrasound dashboard will result in a change to the wavelength of the ultrasound wave as it propagates through tissue?

The following are properties of ultrasound waves as applied in medical imaging, except?1 pointThey are longitudinalThey are electromagneticThey are acousticThey depend upon the medium in which they propagate

An ultrasound beam passing through water or fluid in the body may cause an artifact: acoustic
