摘要： The invention relates to a method for generating an x-ray image. In order to minimize the dose rate the invention proposes that the body to be examined is first irradiated with a first dose rate. On the basis of first signals measured during this process, a second dose rate required for generating the x-ray image is calculated and parameters are determined which are used to subsequently operate the x-ray tube automatically in order to deliver the second dose rate.

摘要： The invention relates to a method for producing x-ray images, by which successive x-ray images are recorded using a first semiconductor detector arranged in a first plane and a second semiconductor detector arranged in a second plane. For the purpose of correcting the x-ray images it is proposed that dark images are recorded intermittently, and these are subtracted from the x-ray images subsequently generated.

摘要： In a method for operating an imaging medical examination device (1), an event of the undisturbed operation of the medical examination device (1) automatically triggers a defect determination (63) for determining a defective pixel possibly present in the image. The event is derived for example from a switch-on process, a calibration process and/or an examination process. Preferably, after the defect determination (63), a correction process (67) is automatically triggered if a defective pixel was detected. A medical examination device (1) has a detection device (31) for automatically determining a defective pixel possibly present in the image, in which case the detection device (31) can be activated by an event of the undisturbed operation of the medical examination device. A correction device (41) for automatically eliminating a defective pixel that has possibly been detected is preferably present.

摘要： With the aid of discriminators on a picture element of an X-ray detector, digital outputs are generated that indicate energy intervals to which X-ray quanta are allocated. If this occurs for adjacent picture elements, a distinction may be made between true coincidences, in which k-fluorescence photons play a part, and random coincidences in which two primary quanta randomly strike adjacent picture elements. The energy of the primary quantum may also be at least roughly reconstructed in the case of true coincidences. An energy-triggering measurement may thereby be provided to the extent that different materials of a picture object should be distinguished.
