ABSTRACT:
An apparatus for determining the air-kerma rate of an x-ray device comprises a data obtaining component for obtaining data of the x-ray device, a calculation component for calculating the air-kerma rate from the obtained data, and an outputting component for outputting the calculated air-kerma rate, where the calculation component uses an algebraic formula for the calculation of the air-kerma rate.
