Method and device for setting the visibility of objects in a projection image generated by radiation

A medical imaging device comprising:

• a radiation source configured to emit radiation and a radiation sensor upon which the radiation is incident after passing through an anatomical tissue, wherein the radiation sensor is configured to output radiation data;
• a projection image generating device configured to generate a projection image from the radiation data;
• a memory configured to store imaging data representing the projection image generated by radiation;
• an artificial intelligence device configured to generate a first partial image from the imaging data using a first semantic class by means of an artificial intelligence algorithm, wherein the first semantic class includes at least one of the following semantic classes:
• a representation of an image of an anatomical structure, a representation of an image of a medical implant, a representation of an image of a medical instrument, and a representation of an image of a medical fastening element;
• a combination device configured to combine the first partial image and the imaging data to generate an output image using a first adjustable function with at least one first parameter, wherein the at least one first parameter is selected by at least one of the following:
• at least one user input, a type of anatomical region to be examined, the first semantic class, or a type of medical procedure;
• a display device configured to display the output image;
• and
• an artificial intelligence training device configured for:
• generating training data for training the artificial intelligence algorithm of the artificial intelligence device based on at least one set of an input image and a first target image;
• and
• generating the first target image by:
• replacing, in a region of a first three-dimensional image model of the patient's tissue from which the input image is generated, imaging data representing the first semantic class with imaging data representing the surrounding tissue, to generate a second three-dimensional image model;
• and
• generating at least one first target image based at least in part on an image generated from the second three-dimensional model;
• wherein each input image corresponds to a projection image of the anatomical region to be examined, which is generated by radiation or the generation of which by radiation is partially or completely simulated;
• and
• wherein at least one first target image has imaging information of the first semantic class.
