An x-ray computed tomography apparatus has a stationary unit and a rotatable unit, carrying an x-ray source and a radiation detector. The rotatable unit rotates around an axis relative to the stationary unit, that proceeds through both units. In order to transmit signals and measured data between the rotating unit and the stationary unit, transmitting/reception devices are mounted at each unit. The transmitting/reception devices transmit directed signals and are automatically oriented toward each other during relative movement caused by rotation of the rotating unit with respect to the stationary unit.
