An increase in red blood cell velocity will_____ the Doppler Shift:
a. increase
b. decrease
c. not change
d. cannot be predicted
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
e. absence of sampling rate
The range for ultrasound begins:
a. 20 Hz
b. 20,000 Hz
c. 2 MHz
d. 15 MHz
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
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
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
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
