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.La présente invention concerne lobservation de vie spatiale simulée dun objet. Afin de fournir des informations spatiales à lutilisateur avec des exigences réduites concernant un maintien dune position particulière, par exemple, par rapport à un dispositif daffichage 3D ou le port ou lactivation de composants supplémentaires, tels que des lunettes 3D, la présente invention vise à générer un faisceau délectrons (38) depuis un agencement de cathode (32) vers une zone cible dune anode (34) et à commander le faisceau délectrons de telle sorte que le faisceau délectrons frappe lanode au niveau dun point focal mobile (44), le faisceau délectrons étant commandé de telle sorte que le point focal se déplace au moins dans une première direction de déplacement (46) transversale à une direction dobservation (48). Ainsi, un rayonnemen
