The increased use of computed tomography and the relatively high radia
tion doses makes it important to evaluate the absorbed dose to the pat
ient, especially for children. In this study measurement results obtai
ned with an anthropomorphic phantom simulating a one year old child ha
ve been compared with two different methods for the calculation of the
absorbed dose. The results agree within +/-15%. The limitations and b
enefits of the methods used are discussed.
