Presice measurements of the photons conversion points in the scintillators are required to achieve a high spatial resolution of the PET system. I have developed a new method of reconstruction of the depth-of-interaction information for PET detectors with dual-side readout. The depth-of-interaction and energy resolutions from Monte-Carlo simulations are presented in this paper. The new method allows to reach depth-of-interaction resolution that is about 0.4~mm (σ) [or about 1.0~mm (FWHM)] for 10-mm long LYSO scintillator. If the precise measurement of the primary photon energy is not a high priority, the new method can be tuned to achieve even better results for the DOI resolution that is better than 0.3~mm (σ) [or better than 0.7~mm (FWHM)].
