Zusammenfassung:The invention relates to a computed tomography radiological apparatus including:an X-ray source (22) capable of emitting an X-ray beam longitudinally towards an object,a device (32) for simultaneously splitting the beam into a plurality of beam portions each having a defined propagation direction relative to the longitudinal direction of emission of said X-ray beam,several sensors (20a-c) intended to receive beam portions which irradiated the object and are arranged transversely side by side relative to the longitudinal direction of the beam, the assembly consisting of X-ray source-splitting device-sensors being capable of turning about an axis of rotation (24) and of adopting different geometric orientations that are angularly shifted with respect to one another in order to, on the one hand, irradiate the object along each one of said geometric orientations of said assembly with the plurality of X-ray beam portions, and, on the other hand, to receive along each one of these geometric orientations the plurality of X-ray beam portions that irradiated the object, the geometric orientation of said assembly being defined by the position of a geometric axis (34) passing, on the one hand, through the focal point of the X-ray source, and, on the other hand, through the axis of rotation (24), the geometric axis (34) having been shifted transversely relative to the center of the plurality of sensors (20a-c).
