Abstract

We developed Photoacoustic Tissue Scanning to tomografically image optically absorbing structures in tissue. With 532 nm light depths down to 6-9 mm were reached. As the samples we used capillaries with blood, human hairs or a variable dilution of Evans blue, embedded in real tissue (chicken breast) or a 10 % solution of Intralipid-10%. Small PVdF piezoelectric hydrophones were used for detection, in scanning mode for imaging purposes. The depth resolution is about 10 ?m, and the lateral resolution is limited by the diameter of the detector (200 ?m in our case).
