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: The disclosed method encompasses pre-registering an anatomical body part with a coordinate system used by an augmented reality device (such as augmented reality glasses) for outputting (e.g. displaying or projecting) augmentation information. An example of the augmentation information is the position (in the real image captured by the augmented reality device) of a fine registration area on the anatomical body part which a user is supposed to identify for fine registration of the anatomical body part with a tracking coordinate system used by a medical position tracking system. The disclosed method is usable in a medical environment such as for surgery or radiotherapy.

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.

Abstract: The disclosed method encompasses registering an augmented reality device such as augmented reality glasses with a tracking coordinate system associated with a position tracking system. This may be effected by different approaches, for example by using a distance measurement unit (depth sensor) of the augmented reality device to determine a position of the augmented reality device relative to an object in a medical environment such as in surgery or radiotherapy/radiosurgery. The object may additionally be tracked by the position tracking system so that on the basis of the distance measurement, a relative position between the augmented reality device and the tracking coordinate system can be determined in order to register the augmented reality device with the position tracking system. This registration allows displaying augmentation information in a desired context and/or at a desired location in the image of the medical environment captured by the augmented reality device.
