  • Patent number: 11246665
    Abstract: During a sEEG (stereo-electroencephalography) intervention into the skull of a patient, there is requirement to drill a large number of trajectories. Typically, instrument stabilisation platforms and robots for protocols requiring only one or two trajectories are rigidly fixed to the skull using surgical anchor members fixed into the skull around the one or two trajectories. However, because sEEG interventions require a large number of trajectories, an impractical number of surgical anchor members need to be fixed into the skull resulting in patient discomfort. Attachment of an intervention platform to all surgical anchor members is not required at once. Accordingly, it is proposed to search for intersection points of the maximum extent of an intervention platform between at least two trajectory entry points on an object of interest of patient, so that at least one surgical anchor member can be shared when the intersection point is at first and the second trajectories.

  • Patent number: 11244472
    Abstract: Disclosed is a computer-implemented method of determining one or more position and/or orientation parameters of an anatomical structure of a body portion. The anatomical structure has a longitudinal shape defining a longitudinal axis. The method includes generating and/or reading, by a data processing system, volumetric data of at least a portion of a subject. The method further includes generating and/or reading, by the data processing system, a deformable template which provides an estimate for a location of the longitudinal axis in the portion of the subject. The method further includes matching, by the data processing system, the deformable template to the volumetric data, thereby obtaining a matched template. The matching comprises using one or more internal energy functions and one or more external energy functions for optimizing an objective function.

  • Patent number: 11216975
    Abstract: A hybrid phantom having marker patches that are visible both in a thermal image captured by a thermal camera and a 3D point cloud generated by a 3D camera. A thermal insulation between the marker, patches and a carrier part of the phantom maintains a temperature difference between the marker patches and the carrier part such that the marker patches are visible in the thermal image. Different optical properties of the marker patches and the carrier part make them distinguishable in the 3D point cloud.

  • Patent number: 11207137
    Abstract: First and second skeleton model data is determined based on first and second surface data of a patient. Each of the skeleton model data describes geometries of rigid anatomic structures of a patient at a different point in time. Skeleton difference data is determined describing differences between the geometries of the rigid anatomic structures. In a next step, movement instruction data is determined which describes movement to be performed by the rigid anatomic structures to minimize the differences, i.e. to correct the posture of the patient. The movement instruction data is for example determined based on anatomy constraint data which describes anatomical movement constraints for the rigid anatomic structures (e.g. range of motion of a joint). An instruction is displayed (e.g. using augmented reality), guiding the user how to move the rigid anatomic structures so as to correct the patient's posture.

  • Patent number: 11135016
    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.

  • Patent number: 11062447
    Abstract: Disclosed is a computer-implemented method of determining a hypersurface image from a tomographic image data set describing a tomographic image of an anatomical body part. The method encompasses a locally depth-of-view-corrected reconstruction of a volumetric data set (pre-operative image data, like CT or MRI image data), in order to e.g. augment volumetric image data onto e.g. a microscope view, or in the head-up display of the microscope. For the depth correction, a surface model of the actual anatomical surface of the anatomical body part is used which encompasses a hypersurface reconstruction pf the volumetric data set. Thus, the correct information related to the tissue at the current visible surface is overlaid.
