abstract c-arm x-ray imaging system provided for acquiring extended three-dimensional images of an object； method for acquiring 3D x-ray image data from an object； computer program element for controlling an apparatus； and computer readable medium the present invention relates to a c-arm x-ray imaging system. In order to provide c-arm systems with an extended three-dimensional field of view, a c-arm x-ray imaging system (10) provided for acquiring extended three-dimensional images of an object is provided, comprising a structure. C-arm (12) with an x-ray source (14) and an x-ray detector (16) mounted through the x-ray source, a motorized unit (22) for rotational movement of the c-arm structure control unit (26). the c-arm structure is provided for rotational scanning around an axis of rotation and around an isocenter acquiring various x-ray projections to generate image data for a reconstructed three-dimensional field of view. the control unit is configured to control the motorized unit, and cause the rotational motion of the c-arm structure to perform a first rotational x-ray scan (50) about a first isocenter (56) with a first axis of rotating to a first field of view and performing at least a second rotational x-ray scan (60) about a second isocenter (62) with a second axis of rotation for a second field of view. the first and second centers of rotation are offset relative to one another such that a connecting line between the first and second isocenters is arranged transverse to the first and second axis of rotation.resumo sistema de formação de imagem de raios x com braço em c provido para adquirir imagens tridimensionais estendidas de um objeto； método para a aquisição de dados de imagem de raios x em 3d de um objeto； elemento de programa de computador para o controle de um aparelho； e meio legível por computador a presente invenção refere-se a um sistema de formação de imagem de raios x com braço em c. a fim de prover sistemas de braço em c com um campo de vis
