Ultrasound Physics: TEST 1 REVIEW
Questions And Answers 100% Pass


Velocity in relationship to frequency & wavelength - answer✔**Speed = frequency x
wavelength**

4 diff types of attenuation - answer✔3 components:
1. Reflection
2. Scattering
3. Absorption
4. Refraction

What's energy per unit area of sound called? - answer✔**Intensity = Power(w) / area (cm2)**

What is peak pressure or height of a wave known as? - answer✔Amplitude
A. How long does it take a beam of sound to make a trip in 1 cm of soft tissue?
B If it Changes to 1 from skin surface to reflector 20 cm deep, how long does it take that sound
to make a round trip? - answer✔A. 13 microseconds (us)


B. 20 x 13 = 260 microseconds

SPTA means? - answer✔Spacial Peak Temporal Average


6 methods to measure and report intensities
1. SPTP - spatial peak, temporal peak
2. SATP - spatial average, temporal peak
3. SPTA - spatial peak, temporal average

4. SATA - spatial average, temporal average
5. SPPA - spatial peak, pulse average
6. SAPA - spatial average, pulse average

What has the highest sound velocity? - answer✔Intensities from Largest to smallest:
SPTP -> Im -> SPPA -> SPTA -> SATA


Temporal Intensities from Largest to smallest:
Itp -> Imax -> Ipa -> Ita

Definition of spatial pulse length? - answer✔Distance that a pulse occupies in space from the
start to the end of a pulse.


Units: mm
Determined by: BOTH Source & Medium
NOT adjustable


**SPL= # cycles x wavelength**


Directly proportional to number of cycles in the pulse
Directly proportional to wavelength
Inversely proportional to Frequency

Frequencies that are not in the ultrasound range? - answer✔audible sound: between 20 Hz and
20kHz
infrasound: less than 20 Hz

Velocity, which has least, greatest, put in increasing order. - answer✔TEMPORAL INTENSITIES
FROM LARGEST TO SMALLEST: Itp, Imax, Ipa, Ita

Definition of propagation speed? - answer✔Rate at which the sound rate travels through a
medium
