Examples of soft tissues
Kidney, liver, brain
Soft tissue and air
Compared to soft tissue, air has extremely high attenuation rates.
What medium has extremely low attenuation?
Water
Which media have low attenuation?
Blood, urine, biologic fluids, and fat
How does soft tissue attenuate sound?
Intermediate attenuation
How does muscle attenuate sound?
Higher attenuation
Which media have even higher attenuation?
Bone and lung
Which medium has extremely high attenuation?
Air
Why does sound attenuate dramatically in air?
Air has an extremely high attenuation rate.
Why does sound attenuate dramatically in lung?
Because of scattering and absorption.
Why does bone have substantial attenuation?
Bone absorbs ultrasound energy to a large extent.
Do biologic fluids attenuate sound as much as soft tissue?
No. They attenuate sound far less than soft tissue.
