CT TECHNOLOGY-FUTURE PERSPECTIVE-

Abstract

The clinical aspects of modern CT technology were discussed. Recent innovations of CT technology were initiated by the introduction of helical scanning which was followed by the development of various new applications including accurate beam-hardening correction, three-dimensional CT diagnosis, and real-time CT. These new CT applications are sharing same characteristics of improved patient benefits. Although current helical scanner improved CT examination, the achievements are not sufficient in terms of both spatial and temporal resolutions. On the basis of these technical backgrounds, development of area detector and corn-beam CT is urgently required.
