Abstract
An embodiment relates to a method for generating a virtual X-ray projection of at least one body region of a patient to be imaged with an X-ray imaging device, a machine-readable data carrier and/or an X-ray imaging device. The method includes acquiring at least one projection data set representing the at least one body region of the patient to be imaged; reconstructing an image data set from the at least one projection data set, the image data set representing local X-ray attenuation values in the at least one body region; replacing at least one local X-ray attenuation value by a modified X-ray attenuation value; forward projecting the modified image data set onto a virtual X-ray radiation detector; calculating intensity values for a plurality of detector elements from the modified projection data set; transforming the calculated intensity values into scan values; and assigning the scan values to an image matrix.
