摘要:
A medical imaging device and a method for providing an image representation supporting inaccurate positioning of an intervention device in a vessel intervention procedure is proposed. Therein an anatomy representation (AR) of a vessel region of interest and at least one angiogram X ray image (RA) and a live fluoroscopy X ray image (LI) are acquired. The following steps are performed when a radio opaque device is fixedly arranged within the vessel region of interest: (a) registering the anatomy representation to the at least one angiogram X ray image in order to provide an anatomy angiogram registration (R1) (b) processing (DP) the at least one angiogram X ray image and the at least one live fluoroscopy X ray image in order to identify in each of the X ray images the radio opaque device (c) registering (R2) the at least one angiogram X ray image to the at least one live fluoroscopy X ray image based on the identified radio opaque device in order to provide an angiogram fluoroscopy registration and (d) combining the anatomy angiogram registration and the angiogram fluoroscopy registration in order to provide an anatomy fluoroscopy registration (GTC RALC). Finally an image representation resulting from the anatomy fluoroscopy registration showing an overlay of live images with the anatomy representation may be output thereby helping a surgeon to accurately position for example a synthetic aortic valve within an aortic root of a heart.
