Title
(DE) STENOSELOKALISIERUNG
(EN) STENOSIS LOCALIZATION
(FR) LOCALISATION DE STÉNOSE
Abstract
(EN) The present invention relates to localizing stenoses. In order to provide improved and facilitated stenosis localization, a device (10) for localizing a stenosis in an angiogram is provided. The device comprises an image supply (12), a data processor (14) and an output (16). The image supply is configured to provide a first image (18) and a second image (20). The first image is an angiographic image that comprises image data representative of a region of interest of a vascular structure in a visible and distinct manner, wherein the vascular structure comprises at least one vessel with at least a part of a stenosis. The second image is a treatment image that comprises image data representative of at least a part of an interventional device arranged within the vascular structure in a state when the stenosis of the vascular structure is treated. The data processor is configured to identify and delineate the stenosis in the first image based on the first image and at least based on device-related content present in the second image. The output is configured to provide an indication of the stenosis.
