Abstract

A through-transmission in vitro measurement procedure was used to estimate the ultrasonic wavefront distortions of five different tissue type: bovine liver, porcine liver, bovine skin, and bovine muscle for two different orientations. Water and Dow Corning 710 was used for distortionless references. Three classes of calculations were performed to evaluate tissue inhomogeneities: correlation coefficient between two waveforms, arrival time shift between two waveforms, and the insertion loss for each waveform relative to water. Results show that waveform distortion increased as a function of spatial location separation for the tissue samples and was significantly greater for the tissue samples compared to the reference materials.
