Computed tomography (CT) is a technique in diagnostic radiology which offers a high diagnostic capability; however, the dose to the patient is high. At the GSF, a catalogue of organ doses resulting from CT examinations was compiled. The doses were calculated for single slices of 1 cm width at positions varying contiguously throughout the body. These dose values can be used as a data base from which organ doses resulting from a particular CT examination can be estimated by suitable summation of the calculated values. The organ doses were calculated for the type of CT scanners most commonly used in the FRG and for three different radiation qualities. For the calculations, the patients were represented by adult mathematical phantoms. The radiation transport in the body was simulated using a Monte Carlo method. The doses were calculated as conversion factors of mean organ doses per air kerma free-in-air on the axis of rotation.
