The invention relates to a method 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 bythe 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 duringthe 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 supportingstructure in order to reduce the determined imbalance, or determining correction data, which is used to correct the imbalance in software. 本发明涉及一种用于校正计算机断层摄影设备的失衡的方法，在计算机断层摄影设备中，具有辐射源的支撑结构被安装在固定的保持架上，其中该支撑结构与辐射源一起围绕测量空间旋转，测量对象被
