The invention relates to a registration system (13) for registering an imaging device (2) like an x-ray C-arm device with a tracking device (4) like an optical shape sensing tracking device. An object detection unit (5) is adapted to a) allow a user to add markers to an image of an object for indicating arbitrary positions on the object and b) provide a representation of the object based on the added markers, wherein a registration unit (6) determines registration parameters based on a location of the object tracked by the tracking device and on the location of the representation. This kind of registration can be performed with any object being visible for the user in the image, thereby permitting to use a wide variety of objects for the registration.

The invention relates to an assisting apparatus (2) for assisting a user in moving an insertion element (11) like a catheter to a target element within, for instance, a person (8). A target element representation representing the target element within the object in its three-dimensional position and three-dimensional orientation and with its size is generated based on a provided target element image. Moreover, a three-dimensional position of the insertion element is tracked, while the insertion element is moved to the target element, and the target element representation and the tracked position of the insertion element are displayed. The three-dimensional position and orientation of the target element relative to the actual position of the insertion element can therefore be shown to the user, while the insertion element is moved to the target element, which allows the user to more accurately and faster move the insertion element to the target element.

摘要:
A volume mapping instrument (20), deployable within a partially or a completely enclosed anatomical volume, employs one or more medical tools (40) with each medical tool (40) being transitional between a deployable structural configuration to orderly position each medical tool (40) within the anatomical volume and a mapping structural configuration to anchor the medical tool (40) against the boundary of the anatomical volume. The volume mapping instrument (20) further employs an optical shape sensor (30) to generate one or more encoded optical signals indicative of a shape of the boundary of the anatomical volume in response to each medical tool (40) being transitioned from the deployable structural configuration to the mapping structural configuration within the anatomical volume. Based on the encoded optical signal(s), a volume mapping module (51) is utilized to map a portion or an entirety of the boundary of the anatomical volume.

A system and method include a shape sensing enabled device too (102) having an optical fiber (126). An interpretation module (115) is configured to receive optical signals from the optical fiber within a structure and interpret the optical signals to determine a shape of the device. An image generation module (140) is configured to receive the shape of the device, register the shape with an image volume of the structure and generate a curved Memory multi-planar reconstruction (CMPR) rendering based on the shape.
