An x-ray diagnostics method is specified, in particular for use in angiography and cardiology, by means of which a particularly good image quality can be achieved in an easily manageable manner for the patient (P) and the medical personnel, at the same time as a comparatively low radiation exposure. Furthermore, a specific x-ray device ( 1 ) for implementing the method comprising an x-ray emitter ( 2 ), an x-ray detector ( 3 ) and a control unit ( 10 ) is specified to control the x-ray emitter ( 2 ). In this way the control unit ( 10 ) is allocated an operating element ( 15 ), by means of which a control parameter (S) characterizing the image quality, the detector input dose or the contrast noise ratio can be continuously varied, as a function of which a number of recording parameters (U,I,t,F) are set by means of the control device ( 10 ).
