METHOD AND APPARATUS FOR CORRECTING ARTIFACTS DURING GENERATION OF X-RAY IMAGES, IN PARTICULAR COMPUTED TOMOGRAPHY, OR RADIOGRAPHY BY MEANS OF TEMPORAL MODULATION OF PRIMARY RADIATION
METHOD AND APPARATUS FOR CORRECTING ARTIFACTS DURING GENERATION OF X-RAY IMAGES, IN PARTICULAR COMPUTED TOMOGRAPHY, OR RADIOGRAPHY BY MEANS OF TEMPORAL MODULATION OF PRIMARY RADIATION
Artifacts caused by scattered radiation when generating X-ray images of objects are corrected using a temporally alterable modulation of the primary radiation. A respective set of originally amplitude-modulated modulation projections of the object is generated and a respective scattered image allocated to the respective modulation projections is calculated. The method is particularly suitable for fast CT scans.
