SonoSim Focused Cardiac Ultrasound part 1
Questions with Detailed Verified Answers
This cardiac ultrasound image was taken using which of the
following imaging windows?
⼀Answer:- parasternal
Which of the following statements correctly describes the use of
Doppler instruments to characterize blood flow?
⼀Answer:- B and C
-As the intercept angle between the ultrasound beam and the blood
flow approaches 90 degrees (perpendicular), the Doppler shift
decreases.
-The alignment of the ultrasound beam directly towards or away from
the direction of blood flow will improve the accuracy of Doppler
instrument measurements.
Continuous-wave Doppler is not subject to the Nyquist limit.
⼀Answer:- True
A Doppler shift occurs when the wave frequency sent out by a
transducer differs from the one returning to the transducer after
being reflected by moving blood cells.
⼀Answer:- true
Which of the following characteristics best describes the ideal
cardiac imaging transducer?

⼀Answer:- small footprint and phased array
Which of the following statements describing the basic physics of
sound-wave transmission principles is correct?
⼀Answer:- A & B
A. Pulse repetition frequency represents the number of pulses occurring
in one second.
B. Duty factor represents the percentage of time that ultrasound
signals are being transmitted.
Which of the following structures is demarcated by the indicator in
this apical two-chamber view image of the heart?
⼀Answer:- anterior wall of leaflet
Which of the following factors influences ultrasound image
orientation on the ultrasound machine screen?
⼀Answer:- a and b
A. Orientation of transducer relative to the patient's body
B. Location of indicator icon on the ultrasound machine screen
Which of the following measurements is required when using
echocardiography to determine cardiac output?
