ARDMS SPI Exam
A mechanical transducer makes use of:
a. Transmit focus
b. Acquire focus
c. Fixed attention
d. Dynamic aperture focusing - ANS-c. Constant recognition; sonographer cannot decide the
vicinity of # of foci. Mechanical transducer makes use of cross sectional imaging, rotating wheel,
wobbler, oscillating reflect
A mirrored image will occur on the boundary of two media if the acoustic impedences of the 2
media are:
a. Equal
b. Exceptional
c. Unchanged
d. Can not be predicted - ANS-b. One of a kind
A strongly targeted transducer implies a:
a. Short focal length; decreased beam divergence
b. Medium focal duration; elevated beam divergence
c. Lengthy focal duration; no beam divergenc
d. Short focal duration; accelerated beam divergence - ANS-d. Quick focal period; elevated
beam divergence
All of the subsequent immediately have an effect on frame fee except:
a. Intensity of penetration
b. Area of view
c. Number of focuses
d. Line density
e. Beam width - ANS-e. Beam width
An increase in basic gain will bring about all the following besides:
a. Growth in photo brightness
b. Increase in output electricity
c. Boom in amplification of the returning sign
d. Decrease danger in bioeffects - ANS-b. Increase in power
An boom in packet size will _______ the frame price - ANS-Decrease
An boom in crimson blood mobile velocity will_____ the Doppler Shift:
a. Increase
, b. Lower
c. Not change
d. Can't be predicted - ANS-a. Growth
An boom inside the quantity of pixels at the display will improve: - ANS-element decision
autocorrelation - ANS-used to convert Doppler shift information into color.
B-mode presentations reflector:
a. Amplitude and distance
b. Amplitude and speed
c. Electricity and path
d. Intensity and speed - ANS-a. Amplitude and distance
Clinical imaging transducers are: - ANS-wide bandwidth; low q element
Damping does not decrease: - ANS-bandwidth
Decibels are the devices for all of the following besides:
a. Amplitude
b. Transmit gain
c. Gain
d. Attenuation
e. TGC
f. Dynamic variety
e. Depth - ANS-e. Depth= mW/cm2
Doppler excessive skip clear out gets rid of: - ANS-excessive amplitude indicators; low velocity
glide
Frequency is - ANS-Cycles per 2nd (Hz)
no longer tormented by sonographer
growth frequency; decrease intensity
How do you decrease duration? - ANS-Increase frequency
Impedance - ANS-the opposition of sound propagation
Increasing propagation speed: - ANS-air, smooth tissue, bone
Increasing transmit benefit increases everything besides: - ANS-frequency
Increasing wavelength will ___________ frequency.
