Chapter 16 & 17

List everything in the more shades chart:

Tissue Harmonics

• results from nonlinear behavior of microbubble

• weaker harmonic signal

• stronger harmonic signal

• created during reflection off of microbubble

A scale’s range of ______ measurement is 30 to 300 pounds- excellent for

measuring the weight of an adult, but not suitable for measuring the weight

of a bunch of grapes or an automobile.

What is dynamic range?

Weak signals (below 30 pounds) are below the system's

These strong signals (above 300 pounds) _______ the system.

the dynamic range of information _______ the more it is processed.

Contrast Harmonics

• occurs as sound propagates in tissue

• created during transmission in tissue

• results from nonlinear behavior of microbubble

• results from nonlinear behavior of transmitted sound beam

Rank the dynamic range of components from least to greatest with their

range. (receiver, display, scan converter, transducer, archive)

Higher MI: 0.1 to 1.0

• some harmonics, resonance, nonlinear behavior, lower frequency sound, higher beam strength, bubble expands moderately

• strongest harmonics, resonance, nonlinear behavior, lower frequency sound, higher beam strength, bubble expands moderately

• no harmonics, backscatter, linear behavior, higher frequency sound, low beam strength, bubble expands very little

• some harmonics, resonance, linear behavior, higher frequency sound, higher beam strength, bubble expands moderately
