Abstract
An X-ray machine includes a radiation source and an image intensifier. A digital camera is downstream of the image intensifier and includes a pixel matrix, wherein the pixel matrix is switchable between a high and a low resolution. The image intensifier displays on an output screen, an image that is dependent on the incident X-radiation and that is picked up by the camera. Imaging behavior of the image intensifier, and thus the sharpness of the image displayed on the output screen, vary depending on the resolution set for the camera.
