Abstract: A method for operating a medical X-ray machine comprising a radiation source (2), a solid state radiation detector (6) having a pixel matrix, a control device (8) for controlling the operation, and a computer (7) for image formation, in which method, for the purpose of forming an image, X-ray radiation is emitted from the radiation source, fed to an object (5) to be radiographed, and received by the radiation detector. Subsequently, the image information is acquired and processed by means of the computer to compose an image to be displayed. The X-ray radiation is applied in the form of at least two separate X-ray pulses (11). The formation and/or composition of the image is based on the acquired image information, specific to the X-ray pulses, of at least a portion of the X-ray pulses.
