  • Patent number: 4754147
    Abstract: A variable collimator 10 for shaping the cross-section of the beam 100 is described. The collimator relies upon rods 16 which are positioned around the beam axis a-a with the rod 16 axis b-b perpendicular to the beam axis. The rods are shaped by shaping member 24 which is cut to the shape of an area of a patient or other surface to be irradiated.

  • Patent number: 4739173
    Abstract: A collimator apparatus (10 or 100) including one or more bundles of nested rods (11, 11a or 101 or 101a or 201) which define a surface (112, 112a) which interferes with a beam of radiation is described. The apparatus particularly uses coil spring (48) between and along the axis (a--a or c--c) of the rods which are compressed by blocks (13, 14, 13a and 14a or 103, 104, 103a and 104a) to lock the rods in position in holes in the blocks. The apparatus is particularly useful for shaping radiation beams for patient treatment.
