ARDMS SPI EXAM LATEST 2024-2025 UPDATE COMPREHENSIVE QUESTIONS
AND CORRECT ANSWERS| ALREADY GRADED A+/PASSED 100%




Which gain will increase the risk of bioeffects? a.
transmit
b. receive
c. gain
d. overall gain - ANSWER-a. transmit


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


The range of frequencies produced by a damped PZT element is
called:
a. fundamental frequencies
b. Q Factor
c. near field
d. bandwith - ANSWER-d. bandwidth


The percentage of time that the ultrasound instrument is emitting
ultrasound is called: a. PRF
b. pulse duration
c. pulse repetition period
