Method for producing digitally reconstructed two-dimensional image i.e. digitally reconstructed radiograph, of patient, involves determining virtual projection value on basis of three-dimensional image data and correction variable

摘要

The method involves determining maximum length, where the length covers a virtual projection jet for penetration of an investigation object in a three-dimensional image data record (2) of a patient (1). Preset length is covered for each virtual projection jet. An associated virtual projection value is determined on the basis of three-dimensional image data of an investigation object and a correction variable that depends on individual length difference and variable whose value lies in the order of magnitude of three-dimensional image data value which represents the object in the data record. An independent claim is also included for a device for producing a digitally reconstructed two-dimensional image from a three-dimensional image data record, comprising a maximum length determining module.
