摘要： 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.

摘要： In a method and x-ray device to determine the value of an x-ray tube voltage to generate at least one image of defined tissue to be examined, at least one provided parameter is used that establishes or describes the desired image quality; based on the dependency of the contrast of the defined tissue to be examined on the spectrum of the x-ray radiation or on the value of the tube voltage of the x-ray tube. The tube voltage is determined also based on a contrast-to-noise ratio that is constantly maintained under consideration of the aforementioned parameter such that the dose of x-ray radiation applied to the patient is optimally low upon setting the value of the tube voltage at the x-ray tube and the acquisition of at least one x-ray projection of the defined tissue.

摘要： The value of a tube voltage of an x-ray tube, used to acquire x-ray projections of a patient in order to generate at least one image in each phase of a multiphase examination, is determined from a contrast-to-noise ratio that establishes the desired image quality of the image in each phase, and the tube current for each tube voltage for each phase is determined given a constantly maintained contrast-to-noise ratio for different tube voltages. For each phase, a value for the dose of x-ray radiation is defined for each different tube voltage and the associated determined tube current. From among the different tube voltages, a tube voltage is set that causes the total dose of x-ray radiation applied to the patient to be as low as possible for all phases of the examination.
