Abstract

To provide visual assistance during medical intervention on the hollow organ (11) of the patient (5), reference data including a reference illustration (19) of the hollow organ (11) is obtained, an X-ray projection image of the hollow organ (11) is generated, overlay information is determined based on the reference data, and the overlay image, corresponding to the X-ray projection image superimposed with the overlay information, is displayed using a display device (4). The reference data contains planning information related to the status of at least one characteristic feature (14, 15a, 15b) of the hollow organ (11) in the reference illustration (19). A reference volume (6') in the reference illustration (19) is determined based on the planning information. A reconstruction (6) of the volume of the patient (5) corresponding to the reference volume (6') is generated using a tomographic fusion method. Registration data is generated by registering the reference volume (6') with the reconstruction (6), and the overlay information is superimposed onto the X-ray projection image based on the registration data.
