When the direction of the wave propagation is parallel to the particle motion of the
medium, the wave being transmitted is called a:
A) surface wave.
B) longitudinal wave.
C) transverse wave.
D) non-linear sound. - ANSWER> B) longitudinal wave


If the sound beam attenuated 6 dB, what will happen to the overall intensity?
A) Quadrupled
B) Doubled
C) Halved
D) Quartered - ANSWER> D) Quartered


Frequency increased from 3 MHz to 6 MHz, what will happen to wavelength?
A) Doubled
B) Quadrupled
C) Halved
D) Quartered - ANSWER> C) Halved


Which of the following is considered the memory of an ultrasound instrument?
a. pulser

, P a g e |2


b. transducer
c. receiver
d. beam former
e. digital scan converter
f. display monitor - ANSWER> e. digital scan converter


Spectral broadening suggest:
a. laminar flow
b. turbulent flow
c. flow away from the transducer
d. flow towards the transducer - ANSWER> b. turbulent flow


With pulse wave Doppler axial resolution: - ANSWER> degrades


What color is usually use in color flow Doppler variance map to indicate turbulent
flow? - ANSWER> green


Doppler high pass filter eliminates: - ANSWER> high amplitude signals; low
velocity flow


The Doppler wall filter is considered a: - ANSWER> high pass filter


The Nyquist Limit is equal to:
a. propagation speed x frequency
b. propagation speed/ wavelength
c. PRF/2

, P a g e |3


d. 4xV^2 - ANSWER> c. PRF/2


Multiple echoes, equally spaced originating from a gas bubble is called:
a. comet tail
b. ring down
c. slice thickness artifact
d. multipath - ANSWER> b. ring down


An increase in red blood cell velocity will_____ the Doppler Shift:
a. increase
b. decrease
c. not change
d. cannot be predicted - ANSWER> a. increase


The primary advantage of CW Doppler is:
a. range resolution
b. range discrimination
c. range ambiguity
d. range gating
e. absence of sampling rate - ANSWER> e. absence of sampling rate


The range for ultrasound begins:
a. 20 Hz
b. 20,000 Hz
c. 2 MHz

, P a g e |4


d. 15 MHz - ANSWER> b. 20,000 Hz (useful frequency range for clinical
imaging is 2MHz-10MHz)


Which instrument control affects the amplitude (dB) of the outgoing signal:
a. gain
b. receiver gain
c. TGC
d. transmit gain
e. overall gain - ANSWER> d. transmit gain; amplitude can be affected by the
sonographer


Which of the following is used to convert Doppler shift information into color:
a. high PRF
b. fast Fourier transform
c. autocorrelation
d. time interval histogram - ANSWER> c. autocorrelation
b is incorrect because fast Fourier transform is the method used to process
conventional Doppler shift information but is too slow a method for color Doppler


Pulse repetition frequency - ANSWER> Number of pulses that an ultrasound
system transmits into the body each second. Hz. Typically 4-15 KHz. PRF and
depth of a view are inversely related: When system is imaging deeper, the pulse
repetition frequency is lower.
Also the number of pulses created each second


The best way to increase the near field length of an ultrasound beam is to: -
ANSWER> increase transducer diameter
