Acousto-optic imaging and reconstruction in highly scattering media: towards quantitative imaging

Abstract

The optical properties of biological tissues are of significant clinical interest. Such media are highly scattering to the near-infrared light which offers the required contrast, and consequently purely optical approaches to imaging tissues at depth suffer from limited spatial resolution. Acousto-optic imaging is a multi-modal technique which overcomes this problem by combining the the optical contrast of near infra-red light with the spatial resolution of ultrasound, permitting millimetre resolution at depths of several centimetres. Raw measurements made using the acousto-optic technique are corrupted by the varying optical fluence in the medium. In this work we demonstrate a method to overcome this limitation by applying a numerical reconstruction algorithm to data collected using an acousto-optic imaging system: this represents a first step towards fully quantitative imaging.
