摘要

medical imaging apparatus for providing an image representation confirming the accurate positioning of an intervention apparatus in vascular intervention procedures, cath lab system, method for providing an image representation confirming the accurate positioning of an intervention apparatus in vascular intervention procedures vascular intervention procedure, computer program, and computer readable media. medical imaging apparatus to provide an image representation that confirms the precise positioning of an intervention apparatus in proposed vascular intervention procedures. In this sense, an anatomy (ra) representation of a vessel region of interest and at least one angiography (ra) x-ray image and real-time fluoroscopy (li) x-ray image are acquired. The following steps are performed when a radio-opaque device is fixedly arranged within the vessel's region of interest: (a) recording the anatomy representation on at least one angiogram x-ray image in order to provide an anatomical- angiography (r1), (b) processing (dp) of at least one angiogram x-ray image and at least one real-time fluoroscopy x-ray image in order to identify in each of the x-ray images the radio apparatus (c) record (r2), the at least one angiogram x-ray image in at least one real-time fluoroscopy x-ray image based on the identified radio-opaque apparatus in order to provide a record fluoroscopy angiogram; and (d) combining the anatomy-angiogram record and the fluoroscopy angiography record to provide a fluoroscopy anatomy record (gtc; ralc). Finally, a representation of the image resulting from the anatomy-fluoroscopy record showing a real-time image overlay with the anatomy representation can be produced by helping the surgeon to accurately position, for example, a synthetic aortic valve within an aortic root. a heart.
