Abstract
The invention relates to a device for adjusting imaging parameters of an X-ray apparatus (), whereby a user pre-defines on a preliminary image an image region of interest (ROI) and a value of the contrast-to-noise ratio (CNR) desired for this image region. Based on the current contrast-to-noise ratio (CNR), new imaging parameters (I, V, L, f, Q) are then calculated for a generator-control module () to control the X-ray apparatus () during an image. By means of the method, the X-ray dose may be reduced to a minimum, while at the same time the desired visibility of a region of interest is ensured.
