Method for correction of scattered radiation errors in radiography and computed tomography with flat panel detectors, involves estimating scattered radiation distribution

摘要

The method involves estimating a scattered radiation distribution. The standard correction terms are calculated. The standard correction terms are noise filtered. The noise filtered standard correction terms are added to the logarithmically measured total projection data. Independent claims are also included for the following: (1) a radiography system for the production of projective or tomographic images (2) a dedicated computer for the creating or editing of projective or tomographic images.
