An x-ray computed tomography apparatus has a rotor on which are mounted at least one x-ray source and one detector. To avoid unwanted deformations of the rotor at high rotation speeds, the rotor is produced at least in segments from a fiber-reinforced composite material with a metal matrix.

X-ray computed tomography apparatus with a rotor formed of composite material

In a method for detection of a stable installation of a system that has a rotation device mounted to rotate around a system axis and an arrangement for detection of measurement values indicative of oscillation of the rotation device, a statistical spread of the measurement values is calculated from N measurement values of different rotations of the rotation device, and the stable installation of the system is detected by a comparison of the calculated statistical spread with a predeterminable threshold. The detected N measurement values can be detected with a known arrangement for determination of an out-of-balance condition, so the method for detection of a stable installation can be implemented without the use of additional hardware components.
