VERSION 2025/2026.
Will not cause a redirection of part of the ultrasound energy - ANS absorption
You are scanning a large mass composed primarily of fat. What will you most likely encounter? -
ANS axial misregistration of object distal to the mass on the screen due to the slower
propagation speed through fat
What 2 conditions must be present to cause a refraction in soundwave? - ANS oblique
incidence and
change in propagation speed
What may be detected with refraction? - ANS lateral misregistration
Of the following structures, which is the most attenuating: blood, bile, lung tissue, calcification?
- ANS calcifications - leaves a shadow
What can you do to enhance the visibility of specular reflectors? - ANS perpendicular
incidence

, What tissue/sound interaction is primarily responsible for imaging internal structures of organs?
- ANS scattering
What tissue/sound interaction is necessary for an ultrasound image? - ANS reflection
For soft tissues, what is needed for determining what a specific impedance is? - ANS bulk
modulus and interface
You are imaging a structure that is highly attenuating. What imaging artifact would you expect
to encounter? - ANS shadowing
Does sound travel slower through air or through soft tissue? - ANS air
An increase in transmit power changes what? - ANS acoustic power
What would you change if image does not show adequate penetration in far field and shows
noise instead of tissue? - ANS decrease the transmit frequency because lower frequency
penetrates better
What is the range of frequencies for human hearing? - ANS 20Hz - 20,000Hz
Maximum cyclical change in quantity is known as? - ANS amplitude
Bulk modulus is closely related to? - ANS stiffness
Time it takes for one ? - ANS period
