Embodiment Construction

[0017] exist figure 1 A side view of a computed tomography camera is illustrated and schematically shown in FIG. and around a vertical figure 1 The rotating shaft 4 of the paper shaft rotates in the direction shown by arrow a. figure 2 briefly shows figure 1 The computed tomography camera 1 shown in figure 1 Another side view in the direction indicated by the arrow B. The housing 3 of the computed tomography camera 1 is not shown in detail in this exemplary embodiment.

[0018] A plurality of components are arranged on the bench 2, in this embodiment, the components include an X-ray radiation source 5, a radiation detector 6 located opposite the X-ray radiation source 5, and a cooling device not shown in detail 7. The cooling device 7 is used to discharge the heat generated by the X-ray tube of the X-ray radiation source 5 during the operation of the computer tomography X-ray camera 1 . When the computer tomography X-ray camera is working, the gantry 2 rotates around th...

Abstract

The invention relates to a computed tomography camera with a gantry (2) rotatable about an axis of rotation (4), with means (11, 13) for determining the unbalance of the gantry (2) , 16a, 16b) and a device (11) for calculating one or more positions where one or more weights (15) should be placed on said stand (2) to compensate for imbalance.

Description

technical field [0001] The invention relates to a computed tomography camera with a gantry rotatable about an axis of rotation, which has a device for determining the unbalance of the gantry. Background technique [0002] A computer tomography camera of the above-mentioned type is described, for example, in US Pat. No. 5,610,968. The computed tomography X-ray camera includes a gantry rotatable around a rotation axis, on which components such as X-ray radiation sources or radiation detectors are arranged, and these components can follow the gantry when the gantry is working. Rotate around the patient to be examined. Possible unbalances of the gantry, ie radial and / or axial wobbles of the gantry relative to its axis of rotation, can lead to unclear images produced with the computer tomography camera. Therefore, in the manufacture of computed tomography cameras, a special balancing device is used to determine the unbalance of the gantry, and one or more weights are attached t...
