1. A method for monitoring an X-ray dosage administered to a patient by a radiation source when recording an image using an X-ray device, comprising:
- describing a recording geometry by parameters;
describing a surface of the patient by a patient model, wherein said surface corresponds to an irradiated skin surface;
determining a location-dependent skin dosage value on the surface as a sum of skin dosage values for a plurality of recordings; and
displaying a representation of the skin dosage value.

Abstract
A method for monitoring the X-ray dosage administered to a patient by a radiation source when using an X-ray device is proposed. The X-ray device is in particular a C-arm X-ray device. A location-dependent dosage value on the surface of the patient is determined with reference to parameters which describe the recording geometry and the radiation that is administered. The surface is described by a patient model in particular. A representation of the dosage value and/or of a value derived therefrom is displayed.
