The present invention relates to simulated spatial live viewing of an object. In order to provide spatial information to the user with reduced requirements concerning to maintain a particular position e.g. with respect to a 3D display or to wear or activate additional components, such as 3D glasses, it is provided to generate an electron beam (38) from a cathode (32) arrangement towards a target area of an anode (34) and to control the electron beam such that the electron beam hits the anode at a moving focal spot (44), wherein the electron beam is controlled such that the focal spot moves at least in a first moving direction (46) transverse to a viewing direction (48). Thus, X-ray radiation (42) is generated by the electron beam impinging on the moving focal spot. Further, it is provided to detect X- ray radiation at least partially passing an object and to generate respective X-ray detection signals. Still further, monoscopic 2D images are generated based on the detection signals, which monoscopic 2D images relate to different view-points as defined by the moving focal spot. The monoscopic X-ray images are displayed from the different view-points. |
