Abstract

A spatial resolution of photoacoustic tomography (PAT) has been limited by the receive frequency significantly lower than that of photoacoustic microscopy. In the present study, an in vivo microcirculation is visualized by a PAT system by using a newly developed spherical array transducer with a center frequency of 10 MHz. Additionally, we propose a novel reconstruction method suppressing the side lobe level with Wiener filtering.
