Question

If you choose a lower-frequency transducer to image a highly attenuating liver, what tradeoff are you making?

a) Decreased penetration
b) Decreased beam intensity
c) Decreased spatial resolution
d) Increased beam refraction
e) Increased round-trip travel time

Answer 1

A lower-frequency transducer offers better penetration in a highly attenuating liver but results in decreased spatial resolution as it provides less detail due to the longer wavelengths associated with lower frequency sounds.ioption c is correct.

Step-by-step explanation:

When choosing a lower-frequency transducer for imaging a highly attenuating liver, you are making the tradeoff of decreased spatial resolution. Lower frequencies offer better penetration through attenuating materials like liver tissue but do not provide as fine a detail.

This is because the wavelength of the sound is inversely related to its frequency; thus, lower frequencies have longer wavelengths, which result in larger spots on the image and less ability to differentiate between small, closely spaced structures.A lower-frequency transducer offers better penetration in a highly attenuating liver but results in decreased spatial resolution as it provides less detail due to the longer wavelengths associated with lower frequency sounds.
