Abstract: The present invention relates to a method for registering a virtual representation of a patient anatomy with a coordinate system of a physical patient anatomy, comprising displaying first overlap data in a head-mounted device, wherein the first overlap data describe from a first perspective onto the physical patient anatomy a first visual overlap between the virtual representation of the patient anatomy and the physical patient anatomy, identifying at least a first area in the first visual overlap and/or at least a first anatomical feature of the patient anatomy in the first visual overlap having at least a minimum degree of alignment between the virtual representation and the physical patient anatomy, displaying second overlap data in the head-mounted device, wherein the second overlap data describe from a second perspective onto the physical patient anatomy a second visual overlap between the virtual representation of the patient anatomy and the physical patient anatomy, and taking into account, during the displaying of the second overlap data, the alignment of the identified first area and/or anatomical feature of the patient anatomy that was identified in the first visual overlap as having at least a minimum degree of alignment between the virtual representation and the physical patient anatomy.

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.

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 computer-implemented medical method of verifying an expected deformation of an elastically deformable and actuator-adjusted medical fine-adjustment unit (1), the method comprising executing, on a processor of a computer, the steps of; —acquiring model data describing a model of the fine-adjustment unit (1), the model reflecting deformation properties of the fine-adjustment unit (1); —acquiring actuator data describing an actuator position of at least one actuator coupled to the fine-adjustment unit (1); —determining, based on the model data and the actuator data, target deformation data describing a target deformation of the fine-adjustment unit (1) caused by the at least one actuator at said actuator position; —acquiring actual deformation data describing an actual deformation of the fine-adjustment unit (1) caused by the at least one actuator at said actuator position; —determining, based on the target deformation data and the actual deformation data, verification data describing whether the target deformation corresponds to the actual deformation. The present invention further relates to a corresponding computer program causing a computer to perform such method, and a corresponding system comprising such a computer.
