Optoacoustic imaging is often performed with onedimensional transducer arrays, in analogy to ultrasound imaging. Optoacoustic imaging using linear arrays offers ease of implementation but comes with several performance drawbacks, in particular poor elevation resolution, i.e. the resolution along the axis perpendicular to the focal plane. Herein, a bi-directional scanning approach using linear arrays is introduced that can improve the imaging performance to quasi-isotropic transverse resolution.
