Imaging method and imaging apparatus

An imaging apparatus comprising:

• an imaging modality configured to:
• generate a first image at a first capture time, wherein the first image represents an object to be depicted, and wherein the first image comprises residues of a contrast agent used for the generation of the first image or from a preceding image generation;
• and
• generate a second image at second capture time that is after the first capture time, wherein the second image represents the object to be depicted, wherein further contrast agent is used in the generation of the second image, and wherein the second image depicts modified residues of the contrast agent as well as a vascular structure of the object highlighted by the further contrast agent;
• and
• at least one processor configured to:
• generate a further first image based on the first image using a predefined model relating to a development over time of the contrast agent present in the object to be depicted when generating the first image, wherein the further first image takes into account the development over time of the contrast agent from the first capture time through to the second capture time, wherein the further first image depicts modified residues of the contrast agent, and wherein the modified residues in the further first image correspond to the modified residues in the second image;
• and
• generate a further second image as a function of the second image and the further first image, wherein, in the further second image, the vascular structure of the object in the second image remains depicted while the modified residues of the contrast agent in the second image are at least partially eliminated.

A non-transitory computer program product with commands, which when executed by an imaging apparatus comprising an imaging modality and at least one processor, cause the imaging apparatus to:

• generate a first image at a first capture time, wherein the first image represents an object to be depicted, and wherein the first image comprises residues of a contrast agent used for the generation of the first image or from a preceding image generation;
• generate a second image at a second capture time that is after the first capture time, wherein the second image represents the object to be depicted, wherein further contrast agent is used in the generation of the second image, and wherein the second image depicts modified residues of the contrast agent as well as a vascular structure of the object highlighted by the further contrast agent;
• generate a further first image based on the first image using a predefined model relating to a development over time of the contrast agent present in the object to be depicted when generating the first image, wherein the further first image takes into account the development over time of the contrast agent from the first capture time through to the second capture time, wherein the further first image depicts modified residues of the contrast agent, and wherein the modified residues in the further first image correspond to the modified residues in the second image;
• and
• generate a further second image as a function of the second image and the further first image, wherein, in the further second image, the vascular structure of the object in the second image remains depicted while the modified residues of the contrast agent in the second image are at least partially eliminated.
