Attenuation: Part 1
Attenuation: Part 1
This video introduces attenuation, the weakening of ultrasound beam intensity as it travels through body tissue. It covers how attenuation is influenced by absorption, reflection, and scattering, explains the relationship between transducer frequency and penetration, and describes how different tissues (bone, fluid) create posterior shadowing and enhancement artifacts.
