ABSTRACT:
This invention teaches method and apparatus for determining backscatter attenuation, for utilizing backscatter attenuation to determine the absolute value of quantitative backscatter from a selected point of the body and/or displaying the absolute value of quantitative backscatter in a unique way. More particularly, backscatter from a selected point in the body resulting from a transmitted ultrasonic signal is detected and the quantitative value of the backscatter signal determined. The invention then determines the backscatter attenuation for moving blood at a particular point which is close to the selected point. The determined backscatter attenuation for blood is then utilized to perform an attenuation correction on the detected backscatter signal, thereby providing the absolute value of quantitative backscatter. The determined absolute value of quantitative backscatter may be color mapped on a display device by, for example, utilizing the absolute value of quantitative backscatter to control at least the color and intensity of the portion of the display imaging the selected point.
