Abstract
For non-invasive diagnostics of cancerous tissue in an early stage, optoacoustic imaging could be highly promising as a modality in common medical ultrasound devices. Optoacoustic (OA) imaging is based on the detection of pressure transients generated by the optical absorption of ns laser pulses. Our goal is to implement an efficient algorithm for calculating in real time tomographies from OA signals collected by a B-scan ulstrasound device. We will give an introduction into the principles of medical optoacoustics and present our methods and latest results. Our aim is to facilitate a discussion about how to do the reconstruction in the most efficient way and maybe initiate an interesting collaboration with the Biomedical Imaging Group.
