Method for generating training data for training an algorithm for estimating positioning variances in an imaging apparatus of an x-ray imaging system

A method for x-ray imaging, the method comprising:

• generating two or more x-ray recordings of an object to be mapped by an x-ray imaging system;
• positioning an imaging apparatus of the x-ray imaging system in accordance with predetermined target positioning data;
• estimating at least one positioning variance by applying an algorithm trained in accordance with a computer-implemented method to the two or more x-ray recordings;
• and
• correcting the two or more x-ray recordings as a function of the at least one estimated positioning variance.

A data processing apparatus comprising:

• at least one processing switching circuit,
• wherein the data processing apparatus is configured to adjust the at least one processing switching circuit by:
• predetermining target positioning data for an imaging apparatus;
• calculating faulty positioning data as a function of the target positioning, wherein the faulty positioning data deviates from the target positioning data by at least one predetermined positioning variance;
• simulating an imaging method, wherein two or more simulated x-ray recordings are generated, wherein a positioning of the imaging apparatus is simulated in accordance with the faulty positioning data;
• generating an annotated training data record that comprises the two or more simulated x-ray recordings and at least one positioning variance as an annotation of the two or more simulated x-ray recordings;
• predicting at least one positioning variance by applying an algorithm to the two or more simulated x-ray recordings;
• and
• adjusting the at least one processing switching circuit as a function of the at least one predicted positioning variance and the at least one positioning variance of the annotated training data record.
