Estimates of Acoustic Inhomogeneities in Skin from the Variation in Backscatter Efficiency at High Ultrasonic Frequencies


A high frequency pulsed ultrasonic system developed to interrogate skin is wtilized to study frequency dependent backscatter efficiency as a means of characterizing biological tissue. The statistical properties of such signals, windowinq artifacts related to signal processing techniques, and various scattering models are discussed in order present the… (More)
