Method for raster scanning an X-ray tube focal spot |
摘要 |
A method and apparatus for producing a scanned beam of penetrating radiation. A beam of particles illuminates a portion of a target, the illuminated portion comprising a focal spot having a centroid. Illumination of the target creates a beam of penetrating radiation such as x-rays. The beam of particles is swept across the target in such a manner that the centroid of the focal spot lies on a line defined by the instantaneous direction of the beam of penetrating radiation as defined, in turn, by a collimating path. |
