Abstract: One or more example embodiments relates to a computed tomography device, having a gantry with a first gantry part, a second gantry part and a third gantry part, wherein the first gantry part includes a rotor with a projection data acquisition system and via a first linear guide is movably mounted relative to the second gantry part such that a translation movement of the first gantry part relative to the second gantry part can be executed, in particular can be executed along the first linear guide.

Abstract: A rotor for a gantry of a computed tomography device is formed as a hollow body at least in one section. The hollow body has a hollow profile cross-section in at least one half-plane defined by the axis of rotation of the rotor.

Abstract: A medical imaging apparatus has a gantry having a stationary gantry housing and a rotor that is rotatable relative to the stationary gantry housing. At least one component to be cooled is arranged at the rotor, and a cooling device produces a cooling of the component. The cooling device has a carrier medium that is ferromagnetic and designed to absorb heat at the rotor and discharge heat to the stationary gantry housing and is transported from the stationary gantry housing to the rotor and back by at least one magnetic field generated by a magnetic field generator.
