Method for generating a virtual X-ray projection on the basis of an image data set obtained with an X-ray imaging device, computer program, data carrier and X-ray imaging device
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.
