Abstract: A concept for facilitating a user interface for interacting with interventional medical devices depicted in an image. The positions of one or more features of at least one interventional medical device are identified. A size and shape of an interactive zone is determined for each feature, where an interactive zone (when provided on a display of a user interface) facilitates interaction with the corresponding feature and/or interventional medical device. The size of the interactive zone is chosen to be larger than the size of the feature. A position for the interactive zone is selected based on the position/position of the corresponding feature in the image. Zone information is then output to define the size, shape and position of the interactive zones with respect to the image.

Abstract: The invention relates to assisting a user in moving an insertion element within an object. A three-dimensional (3D) position and 3D local shape of the insertion element are tracked within the object. Based on the tracked 3D position and 3D local shape of the insertion element, an insertion element representation (42??) representing the insertion element within the object in its 3D position and 3D local shape is generated. Furthermore at least two different markings (78) applied along the length of the insertion element representation (42??) representing indications of the local shape of the insertion element are provided. A display image (60?) including the insertion element representation (42??) with the different markings (78) is displayed. Markings can for example include alternating ring-like structures (78) with alternating lighter and darker colors and/or different colors for the tip and the rest of the insertion element representation for improving 3D visualization of insertion elements.

Abstract: 2D images are registered with 3D volume data. In order to provide 2D/3D registration with a facilitated workflow 3D volume data (112) of an object, having a frame of reference is received. A transformation plane (116) is defined in relation to the 3D volume data. A 2D image of the object with an image plane is received. The transformation plane is projected on the image plane. The frame of reference is aligned with the 2D image. At least one alignment interaction value (128) is projected (130) on the transformation plane to determine (134) at least one transformed interaction value (132). The frame of reference is translated with the at least one transformed interaction value.

Abstract: In a broadcast system (210) each broadcast content item is identified by a broadcast Content Reference Identifier (CRID). In a storage device (220) with a storage (240) each broadcast content item is identified by a local CRID. A processor (230) stores a CRID list that includes for CRIDs an associated validity interval including a starting date and an ending date during which interval the CRID is unique for the content item. When the processor receives (400) a broadcast CRID, it determines (410) an initial validity interval for the broadcast CRID. The initial validity interval includes a starting date and an ending date during which interval the broadcast CRID is unique for the broadcast content item. It then determines (420) whether the initial validity interval overlaps with a validity interval stored in the CRID list for an identical CRID. If there is no overlap it adds (430) the broadcast CRID to the CRID list.
