Tissue Characterization by Ultrasonic Impediography

  • C. Q. Lee
Part of the Acoustical Imaging book series (ACIM, volume 9)

Abstract

An analytical method is presented which can be utilized for tissue characterization. This method permits the simultaneous determination of the attenuation and the impedance profiles. Higher-order reflections are included in the formulation. Computer simulated results for a hypothetical case are included.
