[Estimating patient dose in computerized tomography].
This paper presents a model for the estimation of the effective patient dose in computed tomography. It is demonstrated how equivalent organ doses for selected examination can be estimated on the basis of the scanner-specific axis dose and published conversion factors. Problems and limitations of this method are discussed. The determination of the effective dose from the organ equivalent dosis is explained. The explanations are illustrated by an exemplary calculation, and the doses of the most important CT examinations are summarised.
