  • Abstract
    A new algorithm, based on minimum-mean-square reconstruction error, involves modification of the filter kernel based on the signal-to-noise of each projection target. This algorithm gives improved resolvability relative to other algorithms for the resolution phantom chosen for simulations with Poisson noise.
