Abstract: Disclosed is a computer-implemented method of determining a correspondence between a region of interest as it appears in a first digital medical patient image and as it appears in a second digital medical image. The correspondence is determined by calculating the ratio of overlap of the region of interest with a data object defining an anatomical body part in the first image and the second image and determining whether the larger of the two ratios exceeds a threshold. If the threshold is exceeded, the method assumes that the appearances in the two images describe the same region of interest.

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: Disclosed is a computer-implemented methods of determining distributions of corrections for correcting the segmentation of medical image data, determining corrections for correcting the segmentation of medical image data, training a learning algorithm for determining a segmentation of a digital medical image, and determining a relation between an image representation of the anatomical body part in an individual medical image and a label to be associated with the image representation of the anatomical body part in the individual medical image using the trained machine learning algorithm. The methods encompass reading a plurality of corrections to image segmentations, wherein the corrections themselves may have been manually generated, transforming these corrections into a reference system which is not patient-specific such as an atlas reference system, conducting a statistical analysis of the correction, and applying the re-transformed result of the statistical analysis to patient images. The result of the statistical analysis may also be used to appropriately train a machine learning algorithm for automatic segmentation of patient images. The application of such a trained machine learning algorithm is also part of this disclosure.

Abstract: A radiotherapy feedback device is provided which provides one of a plurality of indication signals for presentation to a surgeon based on the status of a current surgical procedure. In some aspects, an indication signal is provided to the surgeon if the surgical procedure on an anatomical structure is of sufficient status so as to respond well to subsequent radiotherapy.

Abstract: Disclosed is a computer-implemented of adapting a biomechanical model of an anatomical body part of a patient to a current status of the patient. The method encompasses determination of a currently executed step of a workflow such as a medical intervention, the result of the determination serving as a basis for adapting and/or updating a biomechanical model of an anatomical body part to the corresponding current status of the patient. The determination of the current workflow step may also be used as basis for controlling an imaging device for tracking entities around the patient or for imaging the anatomical body part or acquiring further data or for urging the user to perform a specific action such as acquisition of information using a tracked instrument such as a pointer. The biomechanical model has been generated from atlas data. The data sets which are generated according to the current workflow step may additionally or alternatively serve as a basis for determining the current workflow step and/or adapting the further workflow.

Abstract: Provided is a method that encompasses the determination of a virtual trajectory within a virtual representation of a patient's anatomy, wherein the trajectory is defined by a user's visual axis relative to the three-dimensional virtual representation of the patient's anatomy. The method includes acquiring image data which describes the three-dimensional virtual representation of the patient's body part, acquiring position data which describes a spatial position of a user's visual axis within a virtual-world co-ordinate system, determining visualization data based on the image data and the position data, and determining virtual-world trajectory data based on the position data.

Abstract: A computer-implemented medical method of irradiation treatment planning is provided. Therein, an initial coverage volume for a planning target volume, which is to be irradiated in an irradiation treatment with a prescribed dose, is provided. Further, at least one constraint indicative of an allowed dose for an organ at risk is provided. Applying an initial irradiation treatment plan, an organ dose deposited in at least a partial volume of the organ at risk is calculated. Based on comparing the organ dose to the at least one constraint, an amount of violation is determined. Taking into account the determined amount of violation, a reduction coverage volume is calculated for the planning target volume and a virtual planning object is generated based on changing a volume of the organ at risk, such that an overlap region of the virtual planning object and the planning target volume corresponds to the reduction coverage volume. By removing at least a part of the overlap region from the planning target volume, an optimized planning target volume is generated.
