“…However, despite its many advantages, analytical methods suffer from very high computational cost, and in the context of DOT, from an inability to achieve accurate results for realistic 3D problems. Therefore, it has become customary to employ deep learning tools to solve reconstruction problems [6,9,81,86,87]. In the case of diffusive imaging, this refers to the mapping between the optical properties of the media to the measured timeresolved signal registered by the detectors.…”
