    Abstract: A system (IPS) for supporting image-based navigation, comprising: an input interface (IN) for reviving one or more input images acquired by an X-ray imager (IA) whilst two or more medical devices (GW1, GW2) are present in a field of view (FoV) of the X-ray imaging apparatus. An image identifier (ID) identifies the two or more medical devices based on image information in the one or more images. A tagger (TGG) associates a respective, unique, tag with each of at least two of the two or more medical devices (GW1, GW2) so identified. A graphics display generator (GDG) effects displaying on a display device (DD) the one or more input images in a video feed, with the tags included.

    Abstract: The present invention relates to an apparatus for providing a synthetic representation of a vascular structure. It is described to provide (210) at least one 2D X-ray image comprising 2D X-ray image data of a vascular structure of a patient's body part is provided. A 3D model of the body part is provided (220), the 3D model comprising a 3D modelled vascular structure. A 2D projection of the 3D model of the body part is determined (230), the 2D projection of the 3D model of the body part comprising a 2D projection of the 3D modelled vascular structure. The 3D model of the body part is transformed (240). The transform of the 3D model of the body part comprises a determination of the pose of the 3D model of the body part such that a 2D projection of the 3D modelled vascular structure associated with the transformed 3D model of the body part is representative of the 2D X-ray image data of the vascular structure of the patient's body part. A medical report is generated (250) based on information determined from the 3D model.

    Abstract: A medical X-ray imaging arrangement that includes an X-ray source, an X-ray detector, an X-ray beam manipulator device, a processor, and a memory unit. The X-ray beam manipulator device includes an adjustable X-ray beam diaphragm provided between the X-ray source and the X-ray detector. The beam diaphragm includes at least one movable X-ray beam-shaping element and at least one controllable actuator for moving the at least one beam-shaping element according to positioning data provided by the processor. The processor is configured to store positioning data of determined positions of the at least one beam-shaping element for determined attenuation configurations of the diaphragm, and to recall and supply the stored positioning data to the processor for activating the controllable actuator.

    Abstract: A position determination apparatus for determining the position of a working element arranged within an object having an inner structure with respect to a model of the object. The position and shape of a registration element within the inner structure of the object are provided and used for determining a transformation relating the inner structure of the model and the position and shape of the registration element with respect to each other, wherein the position of the working element with respect to the model is determined depending on a provided spatial relation between the working element and the registration element and the determined transformation.

    Abstract: Digital subtraction angiography is used to improve the contrast of images of patient vasculature. A non-contrast image is recorded with no contrast medium injected into the patient, and then a succession of contrast images is captured after the injection of a contrast medium. The non-contrast image is successively registered to the contrast images, and then subtracted. This removes background structures, but leaves the vasculature untouched, making blood vessels easier to see. Artifacts can remain when different motion layers are present in the X-ray image (for example, the spine and the lungs). This application discusses a technique to prevent artifacts occurring when different motion layers are present in an X-ray frame or sequence.
