Which of the following is described as the ability of an object to resist
compression and relates to the hardness of the medium?
a. Stiffness
b. Density
c. Pressure
d. Inertia - ANSWER a. Stiffness
An increase in pulse repetition frequency would lead to:
a. an increase in DF
b. an increase in pulse duration
c. an increase in the number of cycles
d. a decrease in resolution - ANSWER a. an increase in DF
? is this b/c PRP and PRF are reciprocals so if you increase PRF you decrease PRP
which has an inverse relationship to DF?
Which of the following would have the highest propagation speed?
a. Air
b. Bone
c. Soft tissue
d. Water - ANSWER b. Bone
Which of the following would be the lowest propagation speed?
a. Water
,b. soft tissue
c. Bone
d. Lung Tissue - ANSWER D. Lung Tissue (Air)
As imaging depth increases, the pulse repetition frequency must:
a. not change
b. increase
c. decrease
d. pulse repetition frequency doe not relate to imaging depth - ANSWER C.
decrease
Which of the following describes the amount of refraction that occurs at the
interface?
a. Bernoulli's Law
b. Posieuille's law
c. Law of reflection
d. Snells Law - ANSWER d. Snells law
Pressure is typically expressed in :
a. Frequency
b. Pascals
c. Decibels
d. Kilograms per centimeter cubed - ANSWER B. Pascals
The typical range of frequency for diagnostic ultrasound imaging is:
,a. 20 to 20,0000 HZ
b. 1 to 20 MHZ
c. 10 to 20 MHZ
d. 12 to 100 MHZ - ANSWER B. 1 to 20 MHZ
actual 2-12MHZ
The attenuation coefficient in soft tissue is equal to :.
a. one half of the operating frequency
b. double the operating frequency
c. Frequency times path length
d. the total decibels - ANSWER a. one half the operating frequency
Micro denotes:
a. Millionth
b. Hundreth
c. Million
d. Billionth - ANSWER a. millionth
Which of the following is described as the distance over which one cycle occurs?
a. Pulse Duration
b. Duty Factor
c. Period
d. Wavelength - ANSWER d. wavelength
, All of the following are true about stiffness except;
a. it is defined as the ability of an object to resist compression
b. stiffness and propagation speed are indirectly associated
c. increasing stiffness increases propagation speed
d. stiffness may also be referred to as elasticity - ANSWER b - stiffness and
propagation speed are indirectly associated.
they are directly associated .you increase stiffness and your prop speed increases
Areas of high pressure and density are referred to as :
a. Compressions
b. Rarefractions
c. Condensations
d. Rarefractions - ANSWER a . compressions
Spatial pulse length can be calculated by :
a. multiplying the # of cycles times the frequency
b. dividing the period by the frequency
c. multiplying the number of cycles times the wavelength
d. dividing the number of cycles by the wavelength - ANSWER c. # of cycles x
wavelength
Density is typically measured in :
a. Kg per centimeter cubed
