    Abstract: A method for automatic detection of a medical instrument orientation for robotic surgery is presented. The method determines the orientation of a marker device attached to the medical instrument in relation to the robotic system by comparing movement information. The method compares the information about a movement of the marker device from a tracking system with the information about a movement of the robotic arm, which movement data can be acquired by the robotic system. The orientation of the medical instrument with respect to the robotic system can be determined automatically and used for subsequent calculations such as an automatic and efficient precise alignment to a target trajectory or a correct positioning assistance for a mechatronic arm. A computer-implemented medical method of automatically determining an orientation of a medical instrument base in relation to a robotic system is provided.

    Abstract: A cranium bracing system includes a strut mount adapter and a bracing strut, wherein the strut mount adapter is adapted to connect the bracing strut to a cranium hole base member which is rigidly connected to a patient's cranium. The strut mount adapter includes a first connecting section with one or more engaging members configured to engage with the correspondingly formed cranium hole base member to fixedly connect the strut mount adapter to the cranium hole base member. The strut mount adapter further includes a second connecting section configured to engage with a correspondingly formed connecting section of the bracing strut to connect the strut mount adapter to the bracing strut, and a passage extending through the strut mount adapter and having a first passage opening at the first connecting section and an opposed second passage opening.

    Abstract: A computer-implemented medical data processing method for controlling a geometric status of a mechatronic articulable arm. Current geometric status data is acquired describing a current geometric status of the mechatronic articulable arm defined by a set of current spatial relationship between connected elements of the mechatronic articulable arm. Changed geometric status data describing a changed geometric status of the mechatronic articulable arm defined by a set of changed spatial relationship between the connected elements is determined based on current device position data, the current geometric status data, changed device position data, and device definition data. Instruction data describing an instruction for changing the geometric status of the mechatronic articulable arm from the current geometric status to the changed geometric status is determined. The instruction describes changes from the current spatial relationship to the changed spatial relationship.

    Abstract: Disclosed is a computer-implemented method of determining control data for increasing the braking force exerted by a braking mechanism of a mechatronic articulable arm on at least one or all joints connecting the arm elements of the mechatronic articulable arm to a level of braking force which is higher than the level required for locking the joint or joints, respectively. The control data is determined in dependence on both the relative position between the mechatronic articulable arm and an anatomical body part of patient, and a locking state of the mechatronic articulable arm.

    Abstract: The present invention relates to a computer-implemented method of determining a rotational position of an object in a coordinate system of an x-ray imaging device. An x-ray image is generated of an object to which a Moiré marker for x-ray imaging is attached. Subsequently, the Moiré pattern generated by the Moiré marker is analysed and the rotational position of the marker and hence of the object is determined in a calculative manner. The Moiré marker for x-ray imaging includes a pattern which results in a significantly different appearance when being observed from slightly different perspectives. One embodiment example of the Moiré marker for x-ray imaging consists of two layers with patterns produced by a material that shields x-ray as good as possible like for example lead, surrounded and spaced apart by material that is highly transparent in x-ray like for example air or light plastics. The size of the openings in the pattern shall preferably be small compared to the distance of the two layers such that a small change in orientation of the marker results in a fairly significant change in the structure of the second layer seen through the aperture of the first layer. Multiple structures with different hole sizes and layer distances can be used to have a larger working range while maintaining accuracy.
