  • Publication number: 20180023555
    Abstract: A method of assembling a pump for use in a radioactive environment includes positioning tubing between a rotor and a clamp of the pump. The pump includes a pump head that includes a casing, the rotor, and the clamp. The rotor rotates in relation to the casing. The method also includes rotating the rotor for a first period to compress the tubing against the rotor. The tubing is in a dry condition throughout the first period. The method further includes directing liquid into the tubing and rotating the rotor for a second period to compress the tubing against the rotor and direct the liquid through the pump head. The method also includes calibrating the pump.

  • Publication number: 20180018490
    Abstract: A system for manufacturing radionuclide generators includes an enclosure defining a radioactive environment. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. The system also includes a barcode positioned on an object within the enclosure and a scanning system for scanning the barcode. The scanning system includes a camera on the exterior of the enclosure, a mirror, and a conduit extending through a wall of the enclosure for light to travel between the camera and the mirror.

  • Publication number: 20170319778
    Abstract: A system for manufacturing radionuclide generators includes an enclosure defining a radioactive environment. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. The system also includes a pump within the enclosure for transferring fluid through tubing. The pump includes a pump head including a casing, a rotor that rotates in relation to the casing, and a clamp. The tubing extends through the pump head. The clamp compresses the tubing against the rotor and directs radioactive fluid through the tubing as the rotor rotates. The pump also includes a servomotor that controls the rotation of the rotor and a coupling connecting the pump head to the servomotor. The coupling prevents backlash between the servomotor and the rotor during rotation.

  • Publication number: 20170319728
    Abstract: A system includes a radiation containment chamber, an isolator connected to the radiation containment chamber, a rotating transfer door positioned between the radiation containment chamber and the isolator, and an antimicrobial vapor generator connected to the isolator. The rotating transfer door includes a cavity for receiving a radionuclide generator column assembly, and is rotatable between a first position, in which the cavity is open to the radiation containment chamber, and a second position, in which the cavity is open to the isolator. The transfer door is adapted to rotate while antimicrobial vapor is introduced into the isolator by the antimicrobial vapor generator.

  • Publication number: 20170320673
    Abstract: A system for manufacturing radionuclide generators includes an enclosure defining a radioactive environment. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. The system also includes a conveyance system having a forward track and first carriages positioned on and movable along the forward track for conveying racks in a first direction. The conveyance system also includes a first walking beam mechanism magnetically coupled to the first carriages to move the first carriages. The conveyance system further includes a return track and second carriages positioned on and movable along the return track for conveying racks in a second direction opposite the first direction. The forward track and the return track form a loop.

  • Publication number: 20170321244
    Abstract: A method includes sterilizing a column assembly including a column having a parent radionuclide contained therein with a sterilizer. The method further includes transferring the column assembly from the sterilizer to a first clean room environment, transferring the column assembly from the first clean room environment to a second clean room environment, and collecting a sterility test sample from the column assembly within the second clean room environment.

  • Patent number: 9285487
    Abstract: A system for assaying an eluate for Technetium-99m and Molybdenum-99 content includes an inner ionization chamber including a well configured to receive the eluate, an outer ionization chamber concentric with the inner ionization chamber, and attenuating material positioned between the inner and outer ionization chambers. A computing device is configured to determine a Technetium-99m content of the eluate based on a first current measured in the inner ionization chamber, and determine a Molybdenum-99 content of the eluate based on at least a second current measured in the outer ionization chamber.

  • Publication number: 20090166370
    Abstract: An apparatus is used to dispense radiopharmaceuticals from an open vial into capsules. The apparatus is particularly well suited for volatile radiopharmaceuticals such as I-131 radioiodine. The method used with this apparatus enables the operator's hands to remain at a distance from the radiopharmaceutical to reduce extremity exposure which also allows use of highly concentrated stock solutions.
