One of the major challenges of optoacoustic imaging is that it involves relatively weak acoustic signals, which need to be detected with high signal-to-noise ratio (SNR). Because the SNR is generally proportional to the area of the detector's face, large detectors are commonly used. Although the use of such detectors improves the SNR, it may lead to significant signal distortion resulting in artifacts in the reconstructed optoacoustic image. In this work we developed a method for simulating the spatially dependent frequency response of acoustic detectors with arbitrary surface shapes. The frequency response is incorporated into a forward model for optoacoustic propagation. Our method can be used for designing detectors with desired properties and reducing reconstruction artifacts caused by the response of finite-size detectors.
