Abstract
The cone-beam flat panel micro-CT is a high definition imaging system. The CT system is affected by several imperfections and problems, that might lead to serious artifacts that deteriorate the quality of the reconstructed image. Two issues have been discussed in the present work: the source-panel geometric misalignment and the detector lag effect. Two correction methods have been presented and tested on a real CT device to verify their effectiveness in the artifacts compensationFile in questo prodotto:
