Which of the following sets of properties of a test phantom is most relevant when assessing
depth calibration accuracy?
reflector spacing and reflection coefficient
attenuation and speed of sound US in the medium
reflector spacing and US attenuation in the medium
reflector reflection coefficient and US attenuation in the medium
reflector spacing and propagation speed - Answer>>> reflector spacing and propagation speed
Which of the following best describes the features of a sound wave and medium that determine
the speed of sound in the medium?
density of the medium and stiffness of the medium
density of the medium and power of the sound beam
,elasticity of the medium and frequency of the sound beam
stiffness of the medium and elasticity of the medium
pulse repetition period of the sound wave and density of the medium - Answer>>> density of the
medium and stiffness of the medium
Which of the following will result in the highest mechanical index?
high frequency and low power
high intensity and high frequency
low frequency and low signal amplitude
low intensity and low frequency - Answer>>> low frequency and low signal amplitude
While propagating, a sound wave is refracted. Finally, it returns to the transducer. The system
processes the sound wave as if it has:
refracted and returned
traveled in a straight line, reflected and returned
traveled in a straight line, attenuated, reflected & returned - Answer>>> traveled in a straight
line, reflected and returned
Assuming a constant frequency, what happens if the diameter of an unfocused circular transducer
is increased?
the distance to the far field is reduced
the beam width in the near field is reduced
the beam width in the near field is increased
the US wavelength is increased
,the sensitivity is reduced - Answer>>> the beam width in the near field is increased
If the intensity of a sound beam remains unchanged while the beam area is reduced in half, what
has happened to the power?
quadrupled
doubled
halved
unchanged - Answer>>> halved
You are performing a quality assurance study on an US system using a tissue equivalent
phantom. You make an adjustment using a knob on the system console that changes the
appearance of reflector brightness from fully bright to barely visible. What are you evaluating?
resolution
dynamic range
vertical calibration
slice thickness - Answer>>> vertical calibration
An US system is set at 0dB and is transmitting at full intensity . What is the output power when
the system is transmitting at 50% of full intensity?
-3dB
-50dB
10dB
3dB
-10dB - Answer>>> -3dB
