摘要

Abstract: In this work, we present a novel method for the simultaneous acquisition of ultrasonic attenuation and optical absorption using photoacoustically-generated ultrasound. We discuss the theory behind the technique and apply the method to measurements in mammalian tissue samples. We show that the frequency dependence of ultrasonic attenuation measured with this technique is consistent with conventionally determined values and thus holds promise for future work. !6
