c. Sonographers must have a technical aptitude.
d. Sonographers must be able to communicate on different levels.

ANS: a
A sonographer performs ultrasound studies gathering diagnostic data
under both the direct and the indirect supervision of a physician. They

a. 10 to 15 kHz.
b. 1 to 20 kHz.
c. 100 to 1000 Hz.
d. 1 to 20 MHz.

ANS: d
Diagnostic application of ultrasound uses frequencies of 1 to 20 million
cycles per second (1 to 20 MHz).
PTS: 1

b. The beam should be perpendicular to the flow.
c. The Doppler shift is directly proportional to the velocity of the red
blood cell.
d. If the red blood cell moves away from the transducer, then the fall in
frequency is directly proportional to the velocity and direction of the red
blood cell movement.
ANS: b
