,What action below would C: Complete the diagnostic scan in a timely fashion at
be most in keeping with the lowest output power that achieves a quality image.
the ALARA principle while
performing a diagnostic
ultrasound examination?
A: Allow multiple students
to scan an obstetrical
patient because the fetus
is in a good position for
imaging.
B: Prolong the sonogram
to make videos of the
fetus for each family
member.
C: Complete the
diagnostic scan in a timely
fashion at the lowest
output power that
achieves a quality image.
D: Maximize the acoustic
output to brighten the
overall image.
E: Extend the sonogram
beyond the intended
scope of the exam
requisition.
What does the ALARA As Low As Reasonable Achievable
principle stand for?
,During performance of an D: Increase transmit power
obstetrical ultrasound
exam you adjust the
system parameters to
improve the image. Which
of the following
parameters would
increase acoustic
exposure?
A: Increase gain
B: Increase TGC
C: Increase frequency
D: Increase transmit power
E: Increase frame
averaging
While performing a A: Use M-mode instead of pulsed-wave Doppler to
sonogram to minimize risk measure the fetal heart rate.
to the fetus which imaging
mode trade off would be
most applicable?
A: Use M-mode instead of
pulsed-wave Doppler to
measure the fetal heart
rate.
B: Use color Doppler
instead of power Doppler
to image the umbilical
cord.
C: Use pulsed-wave
Doppler instead of power
Doppler to evaluate the
fetal heart.
D: Use harmonics instead
of fundamental to image
the fetal spine.
E: All of the above.
, Gain, TGC, and frame -Sound transmission
averaging do not affect -Exposure
_______ and therefore do not
affect _______.
T or F: Increasing True
frequency does not
increase exposure.
What potential bioeffect B: Heating
occurs through absorption
of sound energy by
tissue?
A: Cavitation
B: Heating
C: Attenuation
D: Reflection
E: Refraction
