Davies SPI Review New Questions with 100% Correct Answers Already Graded A+ What action below would be most in keeping with the ALARA principle while performing a diagnostic ultrasound examination? Allow multiple students to scan an obstetrical patient because the fetus is in a good position for imaging. Prolong the sonogram to make videos of the fetus for each family member. Complete the diagnostic scan in a timely fashion at the lowest output power that achieves a quality image. Maximize the acoustic output to brighten the overall image. Extend the sonogram beyond the intended scope of the exam requisition. 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? 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? Increase gain Increase TGC Increase frequency Increase transmit power Increase frame averaging D: Increase transmit power While performing a sonogram to minimize risk to the fetus which imaging mode trade off would be most applicable? Use M-mode instead of pulsed-wave Doppler to measure the fetal heart rate. Use color Doppler instead of power Doppler to image the umbilical cord. Use pulsed-wave Doppler instead of power Doppler to evaluate the fetal heart. Use harmonics instead of fundamental to image the fetal spine. All of the above. A: Use M-mode instead of pulsed-wave Doppler to measure the fetal heart rate.
