Abstract:
1. An operating method for a medical installation for obtaining images of a subject, having at least one image detector and a control and evaluation device connected thereto, comprising the steps of: selectively operating said medical installation in an activation state or in a waiting state, said waiting state following each activation state; in said activation state, entering a control command to said control and evaluation device for causing said control and evaluation device to operate said medical installation to obtain an image of a subject, including driving said image detector in a detector mode to cause said image detector to acquire a raw image of the subject, said control and evaluation device receiving said raw image from said image detector and determining a useful image from said raw image on the basis of a correction data image for said detector mode; in said waiting state, acquiring no useful image in said control and evaluation device and, after expiration of a basic time interval since a last driving of said image detector in an immediately preceding activation state, in said control and evaluation device updating said correction data image for said detector mode; for updating said correction data image, said control and evaluation device driving said image detector in said detector mode to cause said image detector to acquire am further raw data image, and receiving said further raw image in said control and evaluation device from said image detector and updating said correction data image for said detector mode based on said image raw image in said control and evaluation device; and in said control and evaluation device, additionally updating said correction data image for said detector mode in said activation state if an additional time interval greater than said basic time interval, has elapsed since a last updating of said correction data image.
