    Abstract: An imaging apparatus images a first object (10), like a tip of a catheter, disposed within a second object, such as a vascular structure of a person. A three-dimensional representation of the second object including a representation of a surface (23) of the second object and the position of the first object relative to the position of the second object are provided. A projection (22) of the first object onto the representation of the surface of the second object is determined and shown to a user like a physician on a display (18). The three-dimensional spatial relationship between the first object and the second object is thereby shown in a way that is very native for the user, i.e. a visualization can be provided, which allows the user to easily and accurately grasp the three-dimensional spatial relationship between the first object and the second object.

    Abstract: An optical shape sensing system and method with at least two optical fibers (OSF1, OSF2) both comprising optical shape sensing elements. A processor (P) is arranged to register a coordinate system indicative of a position of one of the optical fibers (OSF1) in space, and to register a position (R2) of the other optical fiber (OSF2) in relation to this coordinate system. An optical console system (C, C1, C2) serves to interrogate the optical shape sensing elements in both optical fibers (OSF1, OSF2), and to accordingly determine a measure of a three-dimensional shape (I) of both optical fibers (OSF1, OSF2), based on the registered position (R2) of the second optical fiber (OSF2) in relation to the coordinate system. This provide the possibility of providing 3D optical shape sensing of the length of both optical fibers (OSF1, OSF2), thus allowing 3D shape reconstruction of e.g. long medical devices with lengths of several meters. More than two shape sensing optical fibers, e.g. incorporated in separate devices, can be registered in this manner in a hierarchical data structure, thus allowing shape sensing of very long instruments.

    Abstract: The invention addresses the problem of correctly positioning a catheter and reducing radiation doses. It relates to an X-ray imaging system (1) for a robotic catheter, comprising said catheter (3), and a processing unit (5) for receiving X-ray images of a patient environment (15). By being adapted to receive one or more auxiliary information items and using said information for determining the catheter position, the processing unit does not entirely have to rely on a large number of scanned image data, thus helping to reduce radiation while correctly delivering the catheter position as a function of as few as a single image, preferably 2D, and said one auxiliary information items. Further, said processing unit allows for at least one of rendering an image and provide said image to a visualization device (21), and providing feedback, e.g. steering commands, to said robotic catheter.

    Abstract: Various cranial surgery OSS registration device embodiments of the present disclosure encompass a cranial surgery facial mask (128), a mask optical shape sensor (126b) having a mask registration shape extending internally within the cranial surgery facial mask (128) and/or externally traversing the cranial surgery facial mask (128), a cranial surgery tool (101), and a tool optical shape sensor (126d) having a tool registration shape extending internally within the cranial surgery tool (101) and/or externally traversing the cranial surgery tool (101). The mask registration shape of the mask optical shape sensor (126b) and the tool registration shape of the tool optical shape sensor (126d) interactively define a spatial registration of the cranial surgery facial mask (128) and the cranial surgery facial mask (128) and the cranial surgery tool (101) to a cranial image.

    Abstract: A controller for displaying a puncture site of an intra-atrial septum for heart repairs includes a memory and a processor (710). The processor (710) executes instructions (784) to perform a process based on image data of a heart that includes a mitral valve and an intra-atrial septum. The process includes defining a mitral valve annulus plane along a mitral valve annulus of the mitral valve and a normal vector perpendicular to the mitral valve annulus plane. The process also includes defining an offset plane that intersects with the intra-atrial septum and that is parallel to the mitral valve annulus plane. A safe zone for the puncture site is identified and displayed on the intra-atrial septum. The safe zone is between a lower boundary plane (456) and an upper boundary plane (455) that are each parallel to the offset plane by specified distances.

    Abstract: Imaging systems and methods are provided, which involve acquiring static volume data using a first imaging technique; segmenting the static volume data to generate a static segmentation; annotating the static segmentation with at least one annotation; acquiring initial dynamic volume data using a second imaging technique different to the first imaging technique; segmenting the initial dynamic volume data to generate a plurality of dynamic segmentations; comparing the static segmentation to each one of the plurality of dynamic segmentations and determining, using the comparisons, a single dynamic segmentation that most closely corresponds to the static segmentation; storing the corresponding single dynamic segmentation in the memory as a reference segmentation; acquiring subsequent dynamic volume data; segmenting the subsequent dynamic volume data to generate at least one subsequent dynamic segmentation; determining a difference between the reference segmentation and the subsequent dynamic segmentation; updating the at least one annotation using the determined difference; and displaying the at least one updated annotation together with the subsequent dynamic volume data.
