发明名称 METHOD FOR PROCESSING RADIOLOGICAL IMAGES TO DETERMINE A 3D POSITION OF A NEEDLE
摘要 A method to process images for interventional imaging, wherein a 3D image of an object is visualized with a medical imaging system, the medical imaging system comprising an X-ray source and a detector, is provided. The method comprises acquiring a plurality of 2D-projected images of the object along a plurality of orientations of the imaging chain, wherein a rectilinear instrument has been inserted into the object. The method also comprises determining a 3D reconstruction of the instrument such that a plurality of 2D projections of the 3D image of the instrument, along the respective orientations in the 2D-projected images of the object were acquired, are closest to the acquired 2D-projected images of the object. The method further comprises superimposing the 3D reconstruction of the instrument over the 3D image of the object so as to obtain a 3D image comprising the object and the instrument.
