    摘要: An image data processor automatically identifies individual picture elements representing embolic material in first and second 2D X-ray images in response to a luminance intensity value of the picture elements exceeding a threshold. The image data processor also automatically identifies individual volume elements in a 3D X-ray image dataset corresponding to the identified individual picture elements by, for an individual picture element, detecting intersection of a projected line with one or more volume elements in the 3D image dataset representing vessels. The projected line substantially passes from the individual picture element to an X-ray radiation source. The display processor initiates generation of data representing a display image showing the identified individual volume elements representing embolic material, with enhanced visualization.

    摘要: A method for providing a 3D image data record of a physiological object with a metal object therein is proposed. To enable an image of the metal object in the physiological object, for instance a biopsy needle in a human patient to be recorded as a 3D image in this patient, two 2D x-ray images of the patient are obtained with the needle with the aid of a biplane x-ray system, and back projection allows a 3D image data record to be generated, which is then subject to a filtering with a gray-scale value window. After filtering, information relating to the position and shape of the metal object in space is obtained. The thus obtained first 3D image data record can be combined with another 3D image data record, in particular with a 3D image data record of the patient without the metal object obtained with the same biplane x-ray system.
