General Considerations — Technical

Abstract

As with other x-ray examinations, the technique will be tailored to answer the clinical questions. Details of the technique used for different organs and different clinical problems are discussed in the appropriate chapters. Only principles of technique which are generally applicable are discussed here. Although the account refers to experience based on the use of the EMI CT5005 General Purpose Scanner, it applies to other scanners of the same type. Most of the text is equally applicable to faster scanners, although these can be expected to give sharper images and can, in some patients, provide more information (figure 2.1).
