Abstract

A new approach to photoacoustic tomography is presented in which a number of spatially overlapping photoacoustic time series measurements are aligned and registered to extend the effective imaging aperture. This approach not only improves the lateral resolution and imaging depth in tissues but also enables imaging of targets that are much larger than the physical size of the detector array.
