Abstract: In some embodiments, the invention refers to a method of image guided navigation. One non-limiting method comprises the steps of: equipping multiple vertebra bodies with patient localizers, segmenting the image data into vertebra body areas wherein segmentation may be performed manually or automatically, for instance by means of a segmenting neural network, and, instead of or in addition to, generating and storing a single, global coordinate system transformation during the patient registration process. In some embodiment, an individual coordinate system transformation for each localizer or vertebra body, respectively, is generated and stored.

Abstract: In some embodiments, invention relates to a Kirschner-wire (10) comprising a localizer coil (20) for an electromagnetic navigation system. The localizer coil (20) is arranged in a distal section of the K-wire (10) at a distance of between 4 mm and 24 mm from a distal tip (14) of the K-wire (10). The localizer coil (20) is electrically connected to two electrically conducting signal lines (22, 24) for passing electric signals from the localizer coil (20) to an electromagnetic navigation system. The electrically conducting signal lines (22, 24) comprise a releasable and reconnectable electric and mechanical connector (30) that allows to disconnect and reconnect distal sections (22.1, 24.1) of the electrically conducting signal lines (22, 24) from proximal sections (22.2, 24.2) of said electrically conducting signal lines (22, 24). The connector (30) is arranged near or at a proximal end of the K-wire (10) such that a cannulated instrument can be slid over the K-wire (10) when the proximal sections (22.2, 24.
