Embodiment Construction

[0029] figure 1 A computed tomography apparatus according to the invention is shown. The computed tomography apparatus includes a gantry 1 with a rotating frame 4 . In the exemplary embodiment shown here, an x-ray source 8 and an x-ray detector 9 interacting with the x-ray source 8 are integrated in the rotating frame 4 . The rotating frame 4 rotates about the longitudinal axis 5 during the recording of the x-ray projections, during which the x-ray source 8 emits the x-rays 2 in the form of an x-ray beam. In particular the X-ray beam can be fan-shaped or cone-shaped. A computed tomograph can also have more than just one x-ray source 8 and more than just one x-ray detector 9 in order to be able to record with the so-called dual-energy method. In the exemplary embodiment shown here, the x-ray source 8 is an x-ray tube. In the exemplary embodiment shown here, the x-ray detector 9 is a line detector with several lines, for example 128 or 256 lines.

Abstract

The invention relates to a rotating frame (4) for a gantry (1) of a computed tomography apparatus, the rotating frame must be designed to be stable mainly in the direction of the centrifugal forces acting upon rotation. Furthermore, in an annular or cylindrical reinforcement frame with sufficient strength and rigidity, centrifugal force can contribute to the stabilization of the components mounted on the inner side of the reinforcement frame. The inventors therefore propose that according to a first variant, a cylindrical base body ( 14 ) with a central axis of rotation is attached to the rotating frame of the gantry for the computer tomograph. The stability of the base body is improved by a reinforcing frame with at least two annular reinforcing elements (15), wherein the reinforcing elements (15) are arranged outside the base body (14) and coaxially to the central axis of rotation. In this case, a reinforcing element ( 15 ) is connected to the base body ( 14 ), the reinforcing element ( 15 ) being designed to absorb centrifugal forces acting on the base body ( 14 ).

Description

technical field [0001] The invention relates to a rotating frame for a gantry of a computer tomograph, a gantry for a computer tomograph and a computer tomograph. Computed tomography machines are designed to produce X-ray images, especially cutaway images. Computed tomography is mainly used in medical imaging, but can also be used in non-destructive testing of materials and other technical areas. An image is reconstructed from measurement data, wherein the measurement data includes projections from a plurality of different projection directions. In order to record projections from different projection directions, the x-ray source and the x-ray detector interacting with the x-ray source are rotated around the recording area. In the construction of a computed tomography apparatus, all components which are intended to be rotatable, in particular the x-ray source and the x-ray detector, are mounted in a so-called swivel frame. Such a rotating frame is also referred to as the "d...
