The invention relates to a method for optical coherence projection tomography of an object comprising the steps of: obtaining optical coherence projection tomography spectroscopic data of the object； obtaining an optical path length, OPL, distribution using the spectroscopic data； selecting a region of interest in the OPL distribution corresponding to ballistic photons based on an estimated value of a size and a refractive index of the object； obtaining at least one of a path-length integrated attenuation coefficient and path-length integrated refractive index from the selected region in the OPL distribution； obtaining at least one sinogram for the obtained at least one of the path-length integrated attenuation coefficient and the obtained path-length integrated refraction index； and reconstructing an image of the object from the obtained at least one sinogram. The invention relates also to a device for performing the method.
