We have proposed a technique for measuring the ultrasonic attenuation constant of tissues in vivo, using a linear- scanned B-mode tomogram which is widely employed in abdominal diagnosis. In this technique, the attenuation constant of a tissue can be estimated by measuring its attenuation related to a reference scattering phantom with known attenuation constant. The merits of this technique are independent of the sensitivity time control (STC) and almost free of the beam focussing. This paper outlines the technique.
