Abstract

Abstract: With the development of technology, more kinds of implants are applied in clinical practices .Those implants, especially metallic implants, could produce metal hardening artifacts which not only have a certain influence in analytical diagnosis diseases, evaluation the treatment effectiveness and prognosis, but also has been plagued by medical imaging workers and clinicians. The combination of medical technology and computer technology has gained a great progress in medical ifeld . Thus the spectral CT could provide a good solution for reducing the artifacts caused by metallic implants. In this paper, we summarize the application of spectral CT imaging in reducing beam-hardening artifacts.

Key words: spectral CT, metallic hardening artifacts, image quality
