  • Contour collimator for use in radiotherapy
    Patent number: 6711237
    Abstract: A contour collimator for radiation therapy has a plurality of diaphragm elements that are movable with respect to each other by means of drive units. The diaphragm elements of the invention are supported only on the side near the drive units for ease of movement. This allows larger contour collimators to be constructed having relatively heavy diaphragm elements while retaining relatively small motors.

  • Radiation system with several radiation sources directed to a control point
    Patent number: 6259762
    Abstract: The radiation system has several radiation sources aimed toward a central point. These radiation sources are on arc element that pivots on an axis. The center can hence be irradiated from different sides. The radiation sources preferably have irregularly adjustable diaphragms. The system is suitable for irradiating any part of the human body. It is easy to manufacture and simple to used.

  • Contour collimator for radiotherapy
    Patent number: 6188748
    Abstract: A contour collimator has a plurality of plate-shaped diaphragm elements movably arranged with respect to each other in a guiding block to form a contour diaphragm for a radiation beam emitted by a radiation source towards the collimator, and at least one drive for moving the diaphragm elements. A drive is associated with each diaphragm element with the drives of a group of diaphragm elements being substantially adjacent, and a driving transmission arranged between each drive and the associated diaphragm element.
