This paper discusses the possibility of increasing the resolution of diffusion optical tomography, using the method of average photon trajectories. It is shown that this method makes it possible to use fast reconstruction algorithms based on both iterative algebraic procedures and integral transformations with filtering of projections. The latter case not only suppresses the discretization noise but also substantially compensates the diffusion smearing of the reconstructed images.
