  • Device for measuring radiation intensity of small sealed radioactive source for cancer therapy
    Patent number: 8476582
    Abstract: A radiation intensity measuring apparatus is provided for an encapsulated sealed radioactive source for brachytherapy, which is capable of measuring radiation intensity of sources with a cartridge enclosed under sterile conditions. The radiation intensity measuring apparatus includes a radiation intensity measuring device for measuring radiation emitted from a source, a holding device for holding a cartridge, and a moving mechanism for moving the holding device to the radiation intensity measuring device. The moving device includes a guide portion for guiding the movement of the holding device so that the holding device moves along a direction perpendicular to an axial direction of a slit, and a moving portion for moving the holding device so that all the sources loaded in the cartridge pass through a position of the slit in a housing space of a housing portion.

  • DEVICE FOR MEASURING RADIATION INTENSITY OF SMALL SEALED RADIOACTIVE SOURCE FOR CANCER THERAPY
    Publication number: 20120326035
    Abstract: Provided is a radiation intensity measuring apparatus for an encapsulated sealed radioactive source for brachytherapy capable of easily and accurately measuring radiation intensity of sources with a cartridge enclosed under sterile conditions. The radiation intensity measuring apparatus for sources S loaded in a cartridge C includes radiation intensity measuring means for measuring radiations emitted from the source S, holding means 30 for holding the cartridge C, and moving means for moving the holding means 30 to the radiation intensity measuring means. The moving means includes a guide portion for guiding the movement of the holding means 30 so that the holding means 30 moves along a direction perpendicular to an axial direction of a slit 15h, and a moving portion for moving the holding means 30 so that all the sources loaded in the cartridge C pass through a position of the slit 15h in housing space of a housing portion.
