  • Collimation system for electron arc therapy
    Patent number: 4598208
    Abstract: An electron collimation system for electron arc therapy treatments consists of a slit collimation system which is movable with the electron beam applicator and is designed to allow for dose compensation in the sagittal direction and a hoop-and-clamp assembly for final field shaping. By correctly designing the shape of the slit in the former and properly adjusting the components of the latter, it is possible to accomplish quite uniform shielding without causing any weight of the shielding material to rest on the patient.

  • Touch detector for electron applicator
    Patent number: 4340825
    Abstract: The present invention provides a touch detector for preventing collision involving an electron therapy applicator. A sensor is suspended from a cable wrapped on a system of pulley wheels and attached to a spring. By adjusting the configuration and tension of the cable properly with respect to the weight of the sensor, the detector sensitivity can be made reasonably independent of the direction of the detected force as well as the position of the apparatus.
