Abstract

Optoacoustic tomography (OAT) conventionally relies on curved detectors to maximize the sensitivity and lateral resolution. Here, we present an alternative paradigm to OAT that creates a virtual detector array with a high angular acceptance and sensitivity by using coded acoustic apertures and a flat piezoelectric detector. Using this approach, we created a 2D virtual array with 1763 elements and performed OAT of a complex 3D object with approximate axial and lateral resolutions of 150 μm and 500 μm in a flat detection geometry, demonstrating an image quality comparable to the one achieved with curved detection geometries.
