Patent ID: 6920201

Claim:
An X-ray control device comprising: a means for selecting one of a plurality of x-ray exposure techniques; a first storage arrangement for storing a number of first sets of preset exposure parameters (S 1i . . . S 1i . . . S 1M ), each first set corresponding to one of the plurality of X-ray exposure techniques; a manual input means for inputting changes to the preset exposure parameters of the selected first set corresponding to the selected x-ray exposure technique; a second storage arrangement in which a number of second sets of exposure parameters (S 211 . . . S 2ij . . . S 2MN ) are stored, each of said second sets of exposure parameters containing the exposure parameters, or values derived therefrom, which are actually used during performance of the selected X-ray exposure technique; means for evaluating a plurality of the second sets of exposure parameters (S 2i1 . . . S 2ij . . . S 2iN ) corresponding to the same x-ray exposure technique in order to drive a new first set of preset exposure parameters for said same x-ray exposure technique; and means for replacing the previously stored set of preset exposure parameters in the first storage arrangement with the new first set of preset exposure parameters.
