Abstract
A computed tomography device has a gantry having a first gantry part, a second gantry part and a flexible material sheet. The first gantry part has a rotor having a projection data acquisition system and is movably mounted, via a linear guiding arrangement, relative to the second gantry part such that the first gantry part is configured for translational movement relative to the second gantry part. The gantry has a tensioning apparatus for the flexible material sheet. The flexible material sheet has a covering section, wherein the covering section spans between the first gantry part and the second gantry part to cover a region of the gantry.
