Abstract A new method of direct (without inverse problem solution using methods of diffuse optical tomography) optical inhomogeneity, such as cysts, hematomas, tumors et al. detection within strongly scattering medium having optical properties of biological tissue is described. The suggested method is based on preprocessing the surface obtained from time-resolved data in the Cartesian frame with consecutive conformal mapping to two cylindrical surfaces. The key method feature is application of late arriving photons approximated by straight lines. The photons are scattered and diffusely transmitted through optically turbid object. The method can be used for express diagnostics of adsorbing and scattering optical inhomogeneities in mammographic tests, traumatology, and diagnostics of brain structures. The method can be implemented with the same hardware and software as for the inverse problem solution. So, the implementation does not require any additional costs.
