Computer tomagraphy method with helicoidal scanning of an examination area |
摘要 |
The invention relates to a CT method which involves helical scanning of an examination zone by means of a cone beam. Measuring data for the three-dimensional tomographic imaging of objects of arbitrary length are now acquired completely and without redundancy. The reconstruction requires only a one-dimensional filtering operation. Particularly simple processing steps are enabled by a rebinning operation during which fan beams which are situated in planes extending parallel to one another and to the axis of rotation are combined.
