Iterative Artifact Reduction IAR
The Iterative Artifact Reduction IAR is a method for the correction of homogeneous components using a characteristic line, which is calculated from the specimen itself by methods of image processing. The patented method is characterized by a number of special features and replaces the extensive characteristic line generation by means of a step wedge.
The calculation of the characteristic line for beam hardening correction is achieved without references. No knowledge about the applied X-Ray spectrum or material properties of the specimen is required. Furthermore IAR considers effects that are not recognized by using a step wedge.
