The invention relates to a tracking reference, comprising: a reference array () featuring a positionally fixed arrangement of at least two tracking markers (); and an interface (A) for detachably coupling the reference array () to a base member (), wherein the interface (A) comprises at least one supporting surface () for contacting the base member (), wherein the interface (A) comprises magnetic means () which generate a force at the reference array, wherein the force (F) is directed away from the supporting surface ().

Detachable tracking reference array

The invention relates to a medical registration apparatus (), comprising &#x2022;two flanks (); &#x2022;a pivot portion () around which at least one of the flanks () is rotatable with respect to a rotation centre () (FIG., FIG.); &#x2022;a contacting portion () on each of the flanks (), each contacting portion () being spaced apart from the rotation centre (); and &#x2022;a sensor () being arranged with an offset (r, FIG.A) to a line (a) connecting the contacting portions (). The invention also relates to a data processing method for use with the medical registration apparatus.

Medical registration apparatus and method for registering an axis

A medical data processing method of determining a spatial relationship between a marker device () and a resection plane () associated with an anatomical structure () of a patient's body, the marker device () being video-detectable by an imaging unit (), the method being constituted to be executed by a computer and comprising the following steps: a) acquiring imaging unit position data describing a predetermined spatial relationship between the imaging unit () and the resection plane; b) acquiring marker device position data describing a spatial relationship between the marker device () and the imaging unit () based on imaging the marker device () with the imaging unit () in order to generate an orientation-dependent image appearance of the marker device (); c) determining, based on the imaging unit position data acquired in step a) and the marker device position data acquired in step b) and based on the orientation-dependent image appearance of the marker device (), resection plane () data describing the spatial relationship between the resection plane () and the marker device ().
