Abstract
In a method and apparatus for generating a two-dimensional projection image from a three-dimensional image data set of an examination object, a three-dimensional image data set of the examination object having a number of voxels is provided to a computer wherein one scan value is associated with one voxel of the examination object. The computer determines at least one value from voxels respectively located along a viewing direction of the three-dimensional image data set, and their scan values, using at least one selection criterion. The at least one determined value is a value that differs from an upper limit value and a lower limit value of the scan values of the voxels located along the viewing direction. The at least one value is used for generating an image point in the two-dimensional projection image.
