ABSTRACT:
In an x-ray apparatus and method to determine the radiation dose in x-ray examinations, the x-ray apparatus has an x-ray radiator, an automatic exposure timer, and a laser range finder to detect the focus-patient separation between the x-ray radiator and a patient, and a computer device determines the necessary radiation dose using the thickness of the body part of the patient to be examined. The thickness is calculated from the acquired focus-patient distance and geometric data of the x-ray apparatus.
