    Abstract: Disclosed is a computer-implemented method which encompasses comparing the requirements for radiation therapy imposed by a patient's individual condition to the capabilities and requirements of different types of treatment machines to determine a suitable radiation treatment strategy including an identification of the treatment machine which shall be used and a treatment plan. Furthermore, a treatment plan is generated by simulating the envisaged radiation treatment. The type of treatment machine associated with a predetermined value for the sum of weights for all fields assigned to that treatment machine is determined as the treatment machine for treating the patient, and corresponding information is output detailing the treatment specifics such as radiation treatment parameters specifically suited for the patient target region tumor thereby reducing radiation exposure, efficient use of the machine and appropriate gating and tracking modes.

    Abstract: A method for determining the relative position between a first camera and a second camera used in a medical application, wherein the first camera captures a 2D image of a phantom, the second camera emits light onto the phantom and analyzes the reflected light, thus generating a 3D point cloud representing points on the surface of the phantom, and the phantom has a planar surface forming a background on which a plurality of 2D markers are formed, wherein one of the background and the 2D markers is reflective, thus reflecting light emitted by the second camera back to the second camera, and the other one is non-reflective, thus not reflecting light emitted by the second camera back to the second camera, the method involving that a) the first camera captures a 2D image of the phantom, b) the second camera generates a 3D point cloud representing the planar surface of the phantom, c) the 2D markers are identified in the 2D image, thus obtaining 2D marker data representing the locations of the 2D markers in the 2D image, d) the 2D markers are identified in the 3D point cloud using the property that points on a non-reflective part of the planar surface are identified as having a larger distance to the second camera than points on a reflective part of the planar surface, thus obtaining 3D marker data representing the locations of the 2D markers in a reference system of the second camera, and e) finding the relative position between the first camera and the second camera by applying a Perspective-n-Points algorithm on the 2D marker data and the 3D marker data.

    Abstract: A head-holder support for attaching a medical head-holder to a patient table is provided that has a rigid base body, an adjustable and lockable head-holder interface at the base body, which is adapted to adjustably couple the head-holder to the base body by providing at least three degrees of freedom for the spatial relative position between the head-holder and the base body, wherein the at least three degrees of freedom are lockable so as to establish a rigid coupling between the head-holder and the base body, and at least one robotic arm interface at the base body, which is adapted to provide a rigid coupling between a robotic arm and the base body.

    Abstract: The present disclosure relates to an optical observation device which is controlled in a sterility preserving manner, and to a corresponding controlling program and/or program storage medium. The optical observation device includes a main structure having at least one optical camera, a support structure adapted to variably position the main structure, and a control unit that receives a sequence of images from the at least one optical camera, searches a current image from the sequence of images for a trackable object, tracks the trackable object shown in the sequence of images subsequent to the current image; and controls adjustable properties of AR-content superimposed with the sequence of images in accordance with a motion of the trackable object, wherein the adjustable properties of the AR-content include a location, orientation, and/or size of the AR-content with respect to the sequence of images.

    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 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.
