VERFAHREN UND VORRICHTUNG ZUM VERMINDERN VISUELLER ARTEFAKTE AUFGRUND VON KOMPRESSION UEBER EINE TRANSFORMIERTE IN MEDIZINISCHEN BILDERN

摘要

A method and apparatus for reducing visual artifacts in medical images reconstructed from compressed imaging data by the approximation of image data rejected during compression. Rejected data is modeled by a statistical distribution such as the Gaussian distribution. The standard deviation of the rejected data is stored with the not-rejected, compressed data. During image reconstruction, the standard deviation is used to approximate the data rejected during compression, and thus to approximate the original image with substantial reduction of visual artifacts.
