The invention relates to an assisting apparatus () for assisting a user in moving an insertion element () like a catheter to a target element within, for instance, a person (). 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.

Disclosed is a surgical navigation system for tracking an instrument relative to a patient. The system can track a portion of the patient, an instrument, and/or both relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a tracking device on the instrument to provide six degree of freedom information regarding the location of the instrument.

Method and apparatus for surgical navigation

A system for tracking a navigated instrument. The system can include a first elongated instrument and a second elongated instrument. The first elongated instrument can have a first proximal end and a first distal end. The first elongated instrument can be adapted to be positioned relative to an anatomy. The second elongated instrument can move adjacent to the first elongated instrument. The second elongated instrument can have a second proximal end and a second distal end. The system can also include at least one tracking device coupled to the second elongated instrument. When the second elongated instrument is in a first position, the at least one tracking device tracks the first distal end of the first elongated instrument, and when the second elongated instrument is in a second position, the at least one tracking device tracks the second distal end of the second elongated instrument.

The invention relates to a registration system () for registering an imaging device () like an x-ray C-arm device with a tracking device () like an optical shape sensing tracking device. An object detection unit () 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 () 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.

A volume mapping instrument (), deployable within a partially or a completely enclosed anatomical volume, employs one or more medical tools () with each medical tool () being transitional between a deployable structural configuration to orderly position each medical tool () within the anatomical volume and a mapping structural configuration to anchor the medical tool () against the boundary of the anatomical volume. The volume mapping instrument () further employs an optical shape sensor () 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 () 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 () is utilized to map a portion or an entirety of the boundary of the anatomical volume.
