Method of processing a radon data based image function and imaging method

摘要

An image processing method for providing a digitized image as an approximation of an image function f, wherein the digitized image comprises a plurality of pixels with a predetermined pixel size, comprises the steps of providing the image function f from Radon data comprising a plurality of projection functions measured corresponding to a plurality of predetermined projection directions (ν), and determining pixel values from the image function, the pixel values representing the digitized image to be obtained, wherein the pixel values are determined in dependence on at least two image function values within the pixel size of the respective pixel. Furthermore, an imaging method and an imaging device using the image processing method are described.
