Abstract

Our goal is the development of a photo-acoustic instrument for 3D imaging of the microvascular structure in tissue, in real time. A photo-acoustic multi-element detector has been designed, which measures in reflection mode. The light source is a pulsed laser with a wavelength of 532nm and the active piezo-material is PVdF. Using a disk detector we have achieved to reconstruction 3D images with a depth and lateral resolution of 10-20 micrometers and 200 micrometers respectively. With the new probe we expect to reduce the measuring time and to sped up the signal and image processing.
