Sonographic Physics Chapter 6

When a sound beam travels through the body it crosses several ___ as it goes from tissue to tissue.

• Waves or Sound waves

• Boundaries or Interfaces

• Boundaries or Sound waves

• Interfaces or Waves

Everytime the beam meets at interface, some sound energy is reflected as an

• wave

• echo

• medium

• sound wave

Reflection heads back towards the transducer and is used to create the

• wavelength

• image

• color flow

• grey scale

The rest of the sound waves from the reflection continues into the next

• wavelength

• sound wave

• medium

• image

The initial sound beam that enters the body is called

• Incident beam

• Reflected beam

• Transmitted beam

• Intensity reflection

What is another name for Incident beam, reflected beam and transmitted beam?

• echo

• ray

• wave

• lazer

The echo that bounces back is called

• Incident beam

• Reflected beam

• Transmitted beam

• Intensity reflection

The sound that crosses an interface is called

• Incident beam

• Reflected beam

• Transmitted beam

• Intensity reflection

What arrow is smaller than the incident arrow because some was reflected.

• Transmitted

• Intensity

• Impedance

• Transmission

At each interface, the transmitted beam gets smaller, what is another name?

• Impedance

• Attenuation

• Reflection

• Intensity
