Computed tomography: Physical principles, instrumentation, and quality control

Abstract

This chapter captures the rapid advancement of CT scanning and includes information relating to both conventional CT scanning (CCTS) and multi-slice CT (MSCT); their advantages, disadvantages and applications. Illustrated throughout, the major components of a CT system are described in relation to the physical principles. An overview of some of the quality control (QC) measures that might be carried out within a CT or SPECT-CT department are also discussed including categories and frequencies of testing.
