Method for creating reconstruction image from previously recorded image data by iterative reconstruction method under consideration of auxiliary conditions, involves detecting position dependent standard deviation of image data

摘要

The method involves detecting a position dependent standard deviation of the image data or a line integral value from the image data (2). The position dependent standard deviation describes the noise of the image data. A reconstructive method-specific another position dependent standard deviation for the reconstruction image is detected from the former standard deviation (3). The reconstruction image is determined using the adjusted parameters by an iterative reconstruction method (5).
