Abstract: The present invention relates to an imaging detector. In order to provide a hybrid X-ray and optical detector with enhanced optical imaging capabilities and a simple design, an imaging detector is provided for capturing optical imaging data and X-ray imaging data. The imaging detector comprises a substrate, a photosensitive sensor, an X-ray scintillator, and an array of optical component arrangements. The photosensitive sensor comprises sensor pixels distributed across the imaging detector. The X-ray scintillator is configured to convert energy of incident X-ray radiation into optical photons. Each optical component arrangement comprises at least one optical component configured for directing incident optical radiation towards the photosensitive sensor. The sensor pixels comprise optical pixels, each coupled with a respective optical component arrangement to receive the incident optical radiation, thereby generating the optical imaging data. The sensor pixels comprise X-ray pixels coupled with the X-ray scintillator to receive the converted optical photons, thereby generating the X-ray imaging data.

Abstract: A system is suggested comprises a main tracking device and a processing unit. The main tracking device includes a plurality of light sources and a plurality of light detectors. On the basis of light pulses, the main tracking device is configured to determine a current 3D position of a plurality of objects in a room. The processing unit is configured to process image information of each of the objects together with the position information so as to generate a visualization of the image information of the objects in spatial relation to each other.

Abstract: The present invention relates to ventricular drain placement. In order to provide improved guidance in ventricular drain placement for emergency situations, a guiding device (10) for emergency ventricular drain placement is provided comprising an image data input (12), a data processor (14) and an output interface (16). The image data input provides optical sensor-based image data of a head of a subject. The data processor generates an optical shape of the head based on the image data and provides a plurality of datasets of heads with different head shapes, wherein each dataset comprises a spatially assigned trajectory for a ventricular drain placement for the respective head shape. The data processor maps the generated optical shape of the head with at least two of the head shapes of the plurality of datasets and determine a best matching head shape of the dataset and further selects the respective assigned trajectory. The output interface provides a projection of the selected assigned trajectory in spatial relation to the head of the subject as adapted guiding path for ventricular drain placement for the subject based on the mapping of the generated optical shape of the head and the determined best matching head shape.

Abstract: The present invention relates to guidance during a medical intervention. In order to provide an improved navigation support with a facilitated setup, a system (10) for navigation support is provided. An image data input (12) receives a plurality of acquired 2D X-ray images of a subject's body from different angles. A set of markers, which are visible in X-ray images and which are detectable by a navigation system, is assigned to the subject. A marker detecting arrangement (16) is provided that detects a current spatial location of the markers assigned to the subject. A data processor (14) reconstructs a 3D volume of the subject based on the plurality of 2D X-ray images. At least a part of the markers is arranged outside the volume covered by the reconstructed 3D volume of the subject, while the markers are visible in the 2D X-ray images. The data processor (14) identifies the markers in the 2D X-ray images based on image data of the plurality of 2D X-ray images outside the 3D volume and determines a spatial location of the markers in relation to the 3D volume of the subject. The data processor (14) also registers the reconstructed 3D volume of the subject to a current spatial position of the subject based on the detected current spatial location of the markers and the determined spatial location of the markers in relation to the 3D volume of the subject. An output interface (18) provides the registered reconstructed 3D volume for navigation.

Abstract: The invention relates to a system (8) for assisting a user in placing a penetrating device in tissue like a pedicle screw (7) in a vertebra’s pedicle. The system generates a virtual view (20) from a penetrating device tip perspective within the tissue in the direction of a path (21) through a model of the tissue. The virtual view is generated based on tracking information indicating a pose of the penetrating device, the model and the path, wherein the virtual view is configured such that it indicates a direction in which the user should move the penetrating device while placing it in the tissue. For instance, it can show a virtual tunnel (801) which is arranged along the path. If a user like a surgeon is provided with such a virtual view, the user can position the penetrating device along the path with a significantly increased accuracy.
