Abstract
Polymer transducers with high center frequencies offer several potential advantages for ultrasonic imaging and tissue characterization of superficial tissue segments. The large bandwidths of these transducers permit resolution of small tissue structures and also provide detailed spectral data for characterizing stochastic tissue elements. We have integrated these transducers with digital systems and conducted initial examinations of the eye, skin, and in- vitro tissue specimens. Computed images have demonstrated superior resolution, and useful signal-to-noise ratios have been obtained for spectral bandwidths exceeding 35 MHz. Further investigations are required to develop compensating processing techniques for acoustic attenuation and frequency-dependent beam characteristics, which can be significant factors over these large bandwidths.
