1. Which gain will increase the risk of bioeffects?
a. transmit
b. receive
c. gain
d. overall gain: a. transmit
2. Which of the following is considered the memory of an ultrasound
instru- ment?
a. pulser
b. transducer
c. receiver
d. beam former
e. digital scan converter
f. display monitor: e. digital scan converter
3. Spectral broadening suggest:
a. laminar flow
b. turbulent flow
c. flow away from the transducer
d. flow towards the transducer: b. turbulent flow
4. With pulse wave Doppler axial resolution:: degrades
5. What color is usually use in color flow Doppler variance map to
indicate turbulent flow?: green
6. Doppler high pass filter eliminates:: high amplitude signals; low
velocity flow
7. The Doppler wall filter is considered a:: high pass filter
8. The Nyquist Limit is equal to:
a. propagation speed x frequency
b. propagation speed/ wavelength
c. PRF/2
d. 4xV^2: c. PRF/2
1/6
, 9. Multiple echoes, equally spaced originating from a gas bubble is called:
a. comet tail
b. ring down
c. slice thickness artifact
d. multipath: b. ring down
10. An increase in red blood
cell velocity will the Doppler Shift:
a. increase
b. decrease
2/6
