Abstract

In a method and x-ray device to assist in the reduction of the dose of x-ray radiation applied to the patient in the acquisition of at least one x-ray projection of the patient, a selected protocol is entered by a user into an x-ray device, the selected protocol being defined for the acquisition of the at least one x-ray projection and including a measure or measures for reduction of the dose of x-ray radiation to be applied to the patient in the acquisition of the at least one x-ray projection. The does reduction measure or measures in the selected protocol are automatically compared in a processor of the x-ray device, with the dose reduction measures that are installed at the x-ray device for reduction of the dose of x-ray radiation to be applied to a patient in the acquisition of the at least one x-ray projection. If the result of the comparison indicates a discrepancy between the dose reduction measure or measures in the selected, defined protocol and those installed in the x-ray device, at least one such measure installed at the x-ray device is visualized as a measure that can be set or activated by the user, that is not yet included in the selected protocol.
