Abstract: In an operating method for a medical installation, in particular an x-ray installation. In activation state of the medical installation, a control and evaluation device determines, upon input of a control command, a useful image of a subject. For this purpose, the control and evaluation device receives raw image of the subject acquired by a detector in a first detector mode, and determines the useful image therefrom on the basis of correction data.

For this purpose, the control and evaluation device receives raw data acquired by the detector and uses it to update the correction data.
