Automatic collimation adaption for dynamic x-ray imaging

A method for generating a trained AI-based model for performing an automatic check of an adapted collimation of an acquired X-ray frame, the method comprising:

• generating labelled input data including input data and validated result data, wherein the labelled input data includes an X-ray frame of an examination object as input data and information related to fulfillment of second criteria of criteria data that are relevant for generating a re-adapted collimation based on the X-ray frame from the examination object as validated result data;
• applying an AI-based model to be trained to the labelled input data to generate result data;
• training the AI-based model based on the result data and the validated result data;
• and
• providing the trained AI-based model.

An adaption device, comprising:

• an input interface configured to
• receive, from a library, criteria data for adapting a collimation, wherein the criteria data are assigned to a selected examination protocol, and wherein the criteria data includes
• first criteria that are relevant for generating an adapted collimation based on optical image data from an examination object, and
• second criteria that are relevant for generating a re-adapted collimation based on an X-ray frame from the examination object,
• receive the optical image data from the examination object, and
• repeatedly receive an X-ray frame from the examination object from an X-ray imaging device;
• an adaption unit configured to generate an adapted collimation based on the optical image data and the first criteria;
• an output interface configured to output the adapted collimation to the X-ray imaging device for adapting the collimation of the X-ray imaging device;
• and
• a checking unit configured to perform an automatic check of the X-ray frame by checking whether the X-ray frame meets the second criteria;
• wherein
• the adaption unit is further configured to
• generate a re-adapted collimation such that the second criteria are more likely fulfilled in response to the automatic check not being passed, and
• maintain the adapted collimation in response to the automatic check being passed, and
• the output interface is further configured to output the maintained adapted collimation or the re-adapted collimation to the X-ray imaging device for re-adapting the collimation of the X-ray imaging device.
