ABSTRACT:
In a method for measuring the dose distribution in a computed tomography apparatus, wherein the dose distribution of an X-ray beam emitted by an X-ray tube with a thickness prescribed by a radiation diaphragm is acquired in the thickness direction for at least one setting of the radiation diaphragm, the dose distribution is acquired in the thickness direction with detector elements of a detector line of the computed tomography system in front of which a slit diaphragm is attached, while adjusting the radiation diaphragm so that each possible setting is set. The dose distribution can be acquired in automated fashion and without manual evaluation that is susceptible to error.
