Method for determining influence of shadow on x-ray image of examining object depending on data set, particularly set of three-dimensional volume data of examining object, involves determining computational information

摘要

The method involves determining computational information on the basis of data set for virtual projection series with multiple projections, which corresponds to different situations of path of rays relative to an examining object (P). A characteristic is determined to quantify the influence of shading by a section. Independent claims are also included for the following: (1) a computer program provided with a sequence of commands; (2) a device for determining the influence of shadow on an x-ray image of an examining object depending on a data set, particularly a set of three-dimensional volume data of an examining object; and (3) a computer tomograph provided with an area detector.
