Abstract

Photoacoustic imaging may become an important imaging tool for several diagnostic procedures, e.g. as an alternative to mammography. Imaging of large objects, sub-mm to mm sized, buried deep in optically turbid tissue is feasible. Our investigation is primarily concentrated on characterizing a photoacoustic imaging system based on an all-optical detection scheme experimentally. The optical detection scheme is based on a novel dual-beam common path interferometer. The experimental investigation is carried out using a phantom comprised of slices of chicken breast tissue and the absorbing object made of silicon rubber. The imaging capability of the system is investigated as a function of the thickness of the tissue sample. By irradiating the absorber directly with a short pulsed laser beam, the influence of changes in the stress wave profile on the detected signal is monitored. Finally, preliminary experiments imaging buried, absorbing objects in tissue are carried out demonstrating the feasibility of this imaging method.
