Method and control facility for controlling a computed tomography system

A system for controlling a computed tomography system, the system comprising:

• at least one processor configured to cause the system to,
• define an examination region of an examination object,
• define a number of interfering structures, wherein an interfering structure is a structure located within a beam path of the computed tomography system and reflects or absorbs X-ray radiation with a strength outside of a tolerance range,
• calculate beam paths of X-rays of a CT examination of the examination region and ascertaining interference angle ranges of a gantry of the computed tomography system at which the beam paths run through the interfering structure and the examination region, and
• reconstruct an image dataset from CT data of received CT data excluding the ascertained interference angle ranges;
• a data interface configured to output control commands for carrying out a CT scan while the gantry rotates, and to receive CT data;
• and
• a data interface configured to output the image dataset.
