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. - Answer-C: Complete the diagnostic
scan in a timely fashion at the lowest output power that achieves a quality image.

A: Increase gain
B: Increase TGC
C: Increase frequency
D: Increase transmit power
E: Increase frame averaging - 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. 2 / 4
