Title: Implementation of Faran's Theory for use in Predicting Acoustic Backscatter Coefficient of Tissue Simulating Materials

The ability to measure the absolute value of the acoustic backscatter coefficient allows investigators to predict scatter size and number density within a region of the human body. This in turn may be useful in determining the disease state of tissue. However, the measurement of absolute backscatter is not standardized and disparity between laboratories exists possibly from experimental error, differences in experimental setup and/or differences in the data reduction algorithms.

Without the availability of "references" with known backscatter, investigators often compare their experimental results to theoretical calculations. The most frequently applied theory was developed for a doctoral dissertation by J.J. Faran in 1951. This presentation will review Faran's Theory from a scientific and mathematical perspective and compare it's predictions to this presentor's experimental measurements.
