    Abstract: A medical imaging system having an X-ray image acquisition device, a plurality of proximity sensors located at components of the X-ray image acquisition device and a processing unit is able to prevent unintended X-ray radiation to an object in a field of irradiation. For this purpose, the processing unit is configured for determining temporal differences of distance information delivered by the proximity sensors, for generating reference distance information based on acquired distance information with an X-ray source, an X-ray detector and the patient support in fixed positions, for filtering out reference distance information from the acquired distance information and for generating a signal in case temporal differences are determined exceeding a predetermined threshold.

    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 protection system (10) and a method for protecting a staff member (6) against X-ray scatter radiation, an X-ray system and a computer readable medium having stored a computer program element for controlling such system. The protection system (10) comprises a location unit (20), and a determination unit (30). The location unit (20) is configured to detect the position of a shielding device (3) and the position of the staff member (6) to be protected. The determination unit (30) is configured to determine an origin (5) of potential X-ray scatter radiation and to determine if the shielding device (3) is positioned to protect the staff member (6) to be protected based on the origin (5) of potential X-ray scatter radiation, the position of the shielding device (3) and the position of the staff member (6).
