Multi-slice technology in computed tomography.

Multi-slice systems represent a considerable advance in CT and will assure the future of the technique for many years to come. This article describes this new technology, indicating its provenance and its position in the evolution of CT. While it does not seek to be a physics and engineering text, enough detail of these are given to allow an informed discussion of the many advantages and a few potential problems associated with the technology. A discussion of a number of applications and a brief consideration of contrast enhancement regimens and the possible need for their modification are presented.
