ABSTRACT:
In a method for calibration of an image-generating x-ray system with a digital x-ray receiver and an x-ray system operating with this calibration method, a number of first offset-corrected bright images are determined at a first constant reference temperature of the x-ray receiver respective at a number first dose settings. A second offset-corrected bright image are subsequently determined at a number of second reference temperatures and at second dose settings that correspond to respective first dose settings. A quotient image is calculated from the second bright image and the first bright image for each of these reference temperatures and is stored. A multi-point calibration at various reference temperatures is implemented with low time expenditure in this manner.
