ABSTRACT:
The present invention provides a novel method and apparatus which allows concomitant imaging and rapid axial beam translation measurements used to calculate the attenuation characteristics of a target body. The present invention employs an ultrasonic scanner which contains a plurality of matched transducer elements. These elements are staggered on a mechanism which sequentially places each transducer opposite an acoustic window at axially spaced positions along a common axis. The present invention also enables axial beam translation techniques to be adapted to current ultrasonic imaging systems.
