Dynamic collimator for a linear accelerator

摘要: This invention relates to a novel dynamic collimator which can be adapted linear accelerator (LINAC). The is such that the shape of jaw arrangement, and therefore collimated beam X radiation from LINAC, changed conformed in very flexible versatile way. In preferred embodiment invention, has three pairs opposing, parallel jaws, each pair jaws being moveable, under control, open close variable amounts. Each set may oriented at 60° orientation transmission area hexagonal shape. Variations on this sixth collimator, including larger numbers also are included within invention. variety shapes with enormous. Irregular target volumes filled by beams nested because nature configuration, giving it added conformal shaping capabilities. Variable angles between so rectangular achieved.
