What is the rate at which power decreases, due to attenuation,
determined by?
- ANSWER-
medium
Is power adjustable by the sonographer? - ANSWER-Yes, initial
power can be
changed.
What is the difference between the maximum and
minimum values of an
acoustic variable? - ANSWER-peak to peak
amplitude
What is the relationship between power and amplitude? -
ANSWER-power is
directly proportional to
amplitude squared
What is the concentration of energy in a sound beam? -
ANSWER-intensity
,How do you calculate intensity? - ANSWER-Divide the beams
power by the
beams cross-
sectional area
intensity (w/cm^2) = power (W)/area (cm^2)
What is the initial intensity determined by? - ANSWER-sound
source
Is initial intensity adjustable by the sonographer? - ANSWER-
Yes
What is the relationship between power and intensity? -
ANSWER-power and
intensity are directly
proportional
What is the relationship between intensity and amplitude? -
ANSWER-intensity
is directly proportional to
amplitude squared
What is the only parameter that is determined by both the
source and the
medium? - ANSWER-
wavelength
, What is the distance or length of one complete cycle? -
ANSWER-wavelength
What is the typical units for wavelength? - ANSWER-mm, cm,
meters
What is wavelength determined by? - ANSWER-sound source
and medium
Is wavelength adjustable by the sonographer? - ANSWER-No
What is the difference between wavelength and period?
- ANSWER-
Wavelength is the length of one cycle
(distance)
Period is how long it takes to complete one
cycle (time)
As frequency increases, wavelength __________. - ANSWER-
decreases
What is the relationship between wavelength and
frequency? - ANSWER-
inversely
related
How do you find the wavelength of sound in soft tissue? -
ANSWER-divide 1.54
