Abstract

Photoacoustic microscopy and tomography are hybrid biomedical imaging technologies that provide optical absorption contrast with ultrasonic spatial resolution. To date, photoacoustic methods have provided little information about the optical scattering properties of tissues. Yet scattering is a key tissue parameter with diagnostic potential for a number of diseases. Moreover, quantitative knowledge of the optical scattering coefficient may prove valuable for improving quantitative estimates of blood oxygen saturation and other functional parameters. We present a new photoacoustic method that shows promise for sensing the local reduced scattering coefficient of tissues.
