Research on CT System Imaging Quality

CT technology has got fast growth after the birth of the first clinical CT imaging system. Its scan range, rate and image quality has been improved hugely. And now CT is widely applied in clinical diagnosis, assistant therapy and other fields. But much issues still exist in CT system development. The image quality is one of the key issues. Factors influencing CT image quality are analyzed from physics and system point in this paper and their related solutions are also discussed.
