A calorimeter is used to degree the: - ANS-Power of the beam
A large bandwidth ends in __________________ - ANS-Improved axial resolution
The shorter the heartbeat, the larger the bandwidth of frequencies gift
As frequency will increase, axial decision will__________ - ANS-enhance
As the propagation velocity of the crystal will increase, the frequency of the transducer: -
ANS-increases
PE element propagation velocity is without delay associated with transducer frequency
Blood flow that varies with breathing is defined as: - ANS-Phasic
Harmonic frequencies are generated: - ANS-as the sound wave travels through the medium
How do you alter your technique to lessen or get rid of move talk on a Doppler tracing? -
ANS-Turn down Doppler advantage
If a 3.Five MHz wave is transmitted thru the media indexed under, the longest wavelength will
be seen inside the wave shifting thru ____________ - ANS-bone
The pace of sound is quickest in bone. Longer wavelengths arise with quicker propagation
speeds
If a 7 MHz wave is transmitted through the media indexed beneath, the shortest wavelength
could be visible inside the wave shifting via ___________ - ANS-air
- Speed of sound is slowest in air
If there may be aliasing with PW Doppler, a sonographer must make use of
____________________ - ANS-CW Doppler
If you're the use of a transducer with a a hundred microsecond pulse repetition perios, a
Doppler shift extra than ____________ will result in aliasing at the show. - ANS-five kHz
If you increase the sector angle from 45 to 90 ranges and no different console adjustments are
made, what happens to the frame rate - ANS-It is reduced to half the unique frame rate
Increasing the transducer frequency will reduce the advent of _____________, at the same time
as growing the advent of ____________ on Doppler assessment. - ANS-variety ambiguity,
