Calculations of the local annihilation rate of positrons in inhomogeneous media have been recently performed. However, the problem was solved only for the positron at the center of the inhomogeneity. This allowed to benefit of the spherical symmetry of the problem. Since the positron is usually an itinerant particle, it is necessary in practical applications to perform computations for every possible coordinates of this particle. In the present work local annihilation rates were obtained for noncentral coordinates of the positron.
