Computer tomography system and method for data determination for an interference-corrected ct recording of a test object

A non-transitory computer readable medium including a computer program product comprising a program code for executing the method steps of a method for data determination for a computer tomography recording of a test object, comprising:

• detecting a sequence of different subsets of measurement transmission recordings of the test object at predetermined, different measurement angle positions to acquire an overall number of measurement transmission recordings based on the different subsets of measurement transmission recordings;
• and
• repeatedly detecting a reference transmission recording of the test object at different reference times at a reference angle position, wherein one reference time each of the different reference times is temporally between two detection processes for the different subsets of measurement transmission recordings.

A computer tomography system for data determination for a computer tomography recording of a test object, comprising:

• a computer tomography arrangement for generating transmission recordings of a test object, wherein the computer tomography arrangement and the test object are arranged rotatably relative to each other;
• and
• a device for processing and controlling which is coupled to the computer tomography arrangement and which is further implemented to detect a sequence of different subsets of measurement transmission recordings of the test object at predetermined angle positions in order to acquire, based on the different subsets of measurement transmission recordings, an overall number of measurement transmission recordings to repeatedly detect a reference transmission recording of the test object at different reference times at a reference angle position, wherein one of the different reference times each is temporally between two detection operations for the different subsets of measurement transmission recordings.
