Abstract: A connector for attaching a reference array in a fixed positional relationship with respect to a patient to be covered by a sterile drape in an attachment area, includes a support to be situated below the drape and a clamping element which is to be situated above the drape and can directly or indirectly hold the reference array or a reference array adaptor, wherein the clamping element clamps the support, with the drape caught between the two, by at least two distinct clamps which clamp the support from at least partly opposing directions in such a way that the positional shift in the clamping element as a result of clamping the drape at the clamping position is compensated for, such that its overall positional shift is substantially zero. A method attaching a reference array in a fixed positional relationship relative to a patient above a sterile drape is also provided.

Abstract: A bone clamp for being attached to a bone, the bone clamp comprising a first lever and a second lever which are connected to each other by a connection, a sliding block and a screw, wherein: the first lever has a first lever arm from a first end of the first lever to the connection and a second lever arm from a second end of the first lever opposite to the first end to the connection, the second lever has a third lever arm from a first end of the second lever to the connection and a fourth lever arm from a second end of the second lever opposite to the first end to the connection, the second ends of the two levers are to get in contact with the bone, the sliding block is slidably attached to the first lever arm, the screw is pivotably mounted in the sliding block, the first lever arm comprises a threaded surface for engaging with the screw mounted in the sliding block, and the sliding block comprises a sliding surface on which the third lever arm slides such that the second ends of the levers approach each other when the sliding block moves along the first lever arm in a predetermined direction.

Abstract: A data processing method for co-registering a medical 3D image dataset and a spatial reference (27), comprising the steps of: acquiring the 3D image dataset, wherein the 3D image dataset represents a medical CT image, a medical MR image or an angiograph of at least a part (20) of a patient and a set of hybrid markers (11); detecting the positions of the hybrid markers (11) in the 3D image dataset so as to obtain a scan matrix representing the arrangement of the set of hybrid markers (11) in the 3D image dataset and the position of the scan matrix in the 3D image dataset; acquiring the positions of the hybrid markers (11) with respect to the spatial reference (27), so as to obtain an image matrix (22a) representing the arrangement of the set of hybrid markers (11) in three-dimensional space and the position of the image matrix (22a) relative to the spatial reference (27); and co-registering the scan matrix and the image matrix (22a).
