  • Locally Adaptive Nonlinear Noise Reduction
    Publication number: 20080310695
    Abstract: An imaging scanner (10) acquires imaging data. A reconstruction processor (30) reconstructs the imaging data into an unfiltered reconstructed image. A local noise mapping processor (64, 120, 136, 140, 142, 152) generates a noise map (68, 68?, 68?) representative of spatially varying noise characteristics in the unfiltered reconstructed image. A locally adaptive non linear noise filter (60) differently filters different regions of the unfiltered reconstructed image in accordance with the noise map (68, 68?, 68?) to produce a filtered reconstructed image.
