ARDMS SPI ACTUAL EXAM WITH
QUESTIONS AND 100% VERIFIED
ANSWERS. [GRADED A+]. LATEST
UPDATE. NEW!!! NEW!!!
An increase in red blood cell velocity will_____ the Doppler Shift:
a. increase
b. decrease
c. not changes
d. cannot be predicted - ANS✔✔-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 - ANS✔✔-e. absence of sampling rate
The range for ultrasound begins:
a. 20 Hz
b. 20,000 Hz
c. 2 MHz
d. 15 MHz - ANS✔✔-b. 20,000 Hz (useful frequency range for clinical imaging is 2MHz-
10MHz)
The transducer frequency is primarily determined by the transducer element:
, a. diameter
b. thickness
c. propagation speed
d. type - ANS✔✔-b. thickness
A strongly focused transducer implies a:
a. short focal length; decreased beam divergence
b. medium focal length; increased beam divergence
c. long focal length; no beam divergenc
d. short focal length; increased beam divergence - ANS✔✔-d. short focal length; increased
beam divergence
B-mode displays reflector:
a. amplitude and distance
b. amplitude and velocity
c. power and direction
d. depth and speed - ANS✔✔-a. amplitude and distance
Which instrument control affects the amplitude (dB) of the outgoing signal:
a. gain
b. receiver gain
c. TGC
d. transmit gain
e. overall gain - ANS✔✔-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 - ANS✔✔-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
