Calibrating digital x-ray detector involves generating calibration image for combination with x-ray image acquired by x-ray detector, whereby pixel contrast of calibration image is smoothed using filter

摘要

The method involves generating a calibration image (K) that is provided for combination with an x-ray image (RB) acquired by the x-ray detector (3), whereby the pixel contrast of the calibration image is smoothed by using a filter. Several calibration images are acquired at time intervals are accumulated to form a time-averaged calibration image. An independent claim is also included for the following: (a) an x-ray device with a digital x-ray detector and an image processing unit.
