  • Publication number: 20230094920
    Abstract: The computed tomography device has a gantry with an opening and a radiation protection apparatus for covering the opening. The radiation protection apparatus includes a radiation protection cover and a pivoting apparatus, wherein an object under examination may be inserted into the opening along a system axis of the gantry when the radiation protection cover is in a first position relative to the gantry. The radiation protection cover is pivotably mounted relative to the gantry about a pivot axis by the pivoting apparatus such that a first pivoting motion of the radiation protection cover about the pivot axis enables the radiation protection cover to be lowered relative to the gantry from the first position to a second position. The computed tomography device may furthermore include at least one of a lighting system or a camera system.

  • Patent number: 11255801
    Abstract: A method is for correcting an imbalance in a computed tomography system, in which a supporting structure includes a radiation source is fitted on a fixed mounting frame. The supporting structure rotates together with the radiation source about a measurement space, in which is fixed in place a measurement object having a known attenuation response for the radiation emitted by the radiation source. The method includes detecting first measurement data of the radiation while the supporting structure rotates about the measurement object, determining an imbalance arising during the rotation of the supporting structure on the basis of the acquired first measurement data of the radiation, and determining a position and a weight of at least one counterweight on the supporting structure in order to reduce the determined imbalance, or determining correction data, which is used to correct the imbalance in software.
