Inverse Problems in Biomedical Photoacoustic Imaging
Biomedical photoacoustic imaging uses laser-generated ultrasonic pulses to image soft tissue with sub-100 micron spatial resolution. One of its successes to date has been in imaging the microvasculature within optically-scattering tissue, such as around small animal brains and in human skin. The experimental photoacoustic scanner used at UCL, and photoacoustic images obtained using it will be shown. Also, the physical principles behind the technique, and some of the inverse problems associated with it will be discussed, including quantitative imaging, and how image reconstruction relates to wave chaos.
