b. time gain compensation
c. depth
d. reject - ANSWERS-c. depth
The sonographer should choose which of the following sweep
speeds when asked to measure a Doppler time interval?
a. high
b. medium
c. low
d. fixed - ANSWERS-a. high
A gain setting which is set too high will have which effect on
resolution:
a. improves
b. degrades resolution
c. will increase resolution at shallow depths
,d. does not effect resolution - ANSWERS-b. degrades resolution
By increasing depth control, frame rate:
a. increases
b. stays the same
c. decreases
d. has no effect on frame rate - ANSWERS-c. decreases
All of the following types of transducers have variable focus
EXCEPT:
a. linear phased array
b. annular phased array

broadening
