What action below would be most in keeping with 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. - CORRECT ANSWER -C: Complete the
diagnostic scan in a timely fashion at the lowest output power
that achieves a quality image.
What does the ALARA principle stand for? - CORRECT
ANSWER -As Low As Reasonable Achievable
During performance of an 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 - CORRECT ANSWER -D:
Increase transmit power
While performing a sonogram to minimize risk 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. - CORRECT ANSWER -A: Use M-
mode instead of pulsed-wave Doppler to measure the fetal
heart rate.
Gain, TGC, and frame averaging do not affect _______ and
therefore do not affect _______. - CORRECT ANSWER --
Sound transmission
-Exposure
T or F: Increasing frequency does not increase exposure. -
CORRECT ANSWER -True
What potential bioeffect occurs through absorption of sound
energy by tissue?
A: Cavitation
