ANGIOGRAPHIC IMAGE ACQUISITION SYSTEM AND METHOD WITH AUTOMATIC SHUTTER ADAPTATION FOR YIELDING A REDUCED FIELD OF VIEW COVERING A SEGMENTED TARGET STRUCTURE OR LESION FOR DECREASING X-RADIATION DOSE IN MINIMALLY INVASIVE X-RAY-GUIDED INTERVENTIONS

摘要

The present invention refers to an angiographic image acquisition system and method which can beneficially be used in the scope of minimally invasive image-guided interventions where image data showing an interventional tool while being navigated through a patient�s cardiovascular and/or cardiac anatomy are intraoperatively acquired based on three-dimensional rotational angiography (3DRA) imaging and image data for three-dimensionally reconstructing this anatomy are pre-interventionally acquired by means of MR, CT, C-arm-based 3DRA or any other imaging modality. In particular, the present invention relates to a system and method for graphically visualizing a pre-interventionally virtual 3D representation of a patient�s coronary artery tree�s vessel segments in a region of interest of a patient�s cardiovascular system to be three-dimensio�nally reconstructed.
