摘要： 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.

摘要： 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.

摘要： An X-ray imaging guiding system for positioning a region of interest of a patient for X-ray image acquisition includes an X-ray detector arrangement, and graphical positioning information. The graphical positioning information includes a graphical target anatomy representation. The graphical target positioning information is provided in spatial relation with the X-ray detector arrangement. The graphical target anatomy representation indicates a target position of a respective anatomy of the patient for a determined X-ray image acquisition. Further, the graphical positioning information is adaptable in accordance with the determined X-ray image acquisition.

摘要： An apparatus configured to generate for display a plurality of vasculature views alongside a live fluoroscopy image. The views are selected in such a way that they allow visualizing the 3D structure of the vasculature segment in which the device is currently navigating. The view is best relative to one or a weighted average of a plurality of goodness of view standards. As the device progresses and new fluoroscopy images are acquired, the views are updated accordingly.

摘要： The present invention relates to image processing for enhancing ultrasound images. In order to provide image data showing the current situation, for example in a region of interest of a patient, an image processing device (10) for enhancing ultrasound images is provided that comprises an image data input unit (12), a central processing unit (14), and a display unit (16). The image data input unit is configured to provide an ultrasound image of a region of interest of an object, and to provide an X-ray image of the region of interest of the object. The central processing unit is configured to select a predetermined image area in the X-ray image, to register the ultrasound image and the X-ray image, to detect the predetermined area in the ultrasound image based on the registered selected predetermined image area, and to highlight at least a part of the detected area in the ultrasound image to generate a boosted ultrasound image. The display unit is configured to provide the boosted ultrasound image as guiding information on a display area (18).

摘要： The invention relates to a position determination apparatus for determining the position of a working element (5) arranged within an object (3) having an inner structure with respect to a model of the object. The position and shape of a registration element (7) 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. In this way the position of the working element with respect to the model of the object can be determined without necessarily requiring x-ray projection images showing the working element and, thus, without necessarily applying x-rays to the object.
