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.

摘要： The present invention relates to pairing an anatomy representation with live images. In order to provide an enhanced and more flexible pairing of an anatomy representation with live images, for pairing an anatomy representation with live images, reference projected-anatomy image data of a device in a spatial relation to the anatomy is provided (100), wherein the image data comprises at least a first and second image showing the device from different viewing angles. Further, an anatomy representation with an anatomy frame of reference is provided (200). The anatomy representation is brought (300) into spatial coherence with the at least first and second image of the reference projected anatomy image data. A three-dimensional model of the device within the anatomy frame of reference is computed (400) from the projected anatomy image data. At least one live image is provided (500) containing the device. The model and the at least one live image are registered (600) based on the device information contained in the live image. The anatomy representation is brought (700) into spatial correspondence with the at least one live image based on the registering of the model and the at least one live image. The registered anatomy is combined (800) with the at least one live image.
