Method for preparing CT image displays, and an arithmetic logic unit for carrying out this method

Abstract

A method is disclosed for preparing CT image displays. In at least one embodiment, the method includes compiling N≧2 CT image data records of an area of a patient on the basis of N different X-ray energy spectra, each pixel or voxel being assigned an N-tuple CT numbers, each CT number of the N-tuple being assigned to the absorption value of one of the N X-ray energy spectra; carrying out material destruction over at least one predetermined subarea of the area of the patient represented in the CT image data records with reference to at least three materials including at least bone mineral, yellow bone marrow and red bone marrow; and outputting and/or displaying at least one CT image data record at least with reference to the predetermined subarea with absorption values relating to one of the N X-ray energy spectra or to a mathematically simulated spectrum from which the bone mineral content is extracted.
