In some embodiments, the alignment adaptor may be utilized to at least assist in aligning various components of an elution system. For example, in some embodiments, the alignment adaptor may be utilized to at least generally assist in aligning an aperture defined in a lid of the elution system and an elution needle of a radioisotope generator. In some embodiments, the alignment adaptor may be utilized to at least generally assist in aligning an elution assembly (e.g., elution shield housing an eluate vial) and an elution needle of a radioisotope generator. Further, in some embodiments, the alignment adaptor may be utilized to at least generally assist in aligning an eluant container (e.g., bottle of eluant) and a needle of a radioisotope generator. | 08-28-2008 |
20080277594 | Radiopharmaceutical System and Method Utilizing Radio-Frequency Identification Tags - The invention, in one characterization, may be said to be directed to a radiopharmaceutical system. In some embodiments, the system may include a radioisotope elution component and a radio-frequency identification (RFID) tag coupled to the radioisotope elution component. Other embodiments may include a radiation shielded enclosure having an interior, an exterior, and a radio-frequency identification (RFID) communication transmission passage extending between the interior and the exterior. | 11-13-2008 |
20090001283 | Method for the chemical separation of GE-68 from its daughter Ga-68 - The present invention is directed to a generator apparatus for separating a daughter gallium-68 radioisotope substantially free of impurities from a parent gernanium-68 radioisotope, including a first resin-containing column containing parent gernanium-68 radioisotope and daughter gallium-68 radioisotope, a source of first eluent connected to said first resin-containing column for separating daughter gallium-68 radioisotope from the first resin-containing column, said first eluent including citrate whereby the separated gallium is in the form of gallium citrate, a mixing space connected to said first resin-containing column for admixing a source of hydrochloric acid with said separated gallium citrate whereby gallium citrate is converted to gallium tetrachloride, a second resin-containing column for retention of gallium-68 tetrachloride, and, a source of second eluent connected to said second resin-containing column for eluting the daughter gallium-68 radioisotope from said second resin-containing column. | 01-01-2009 |
20090266998 | Self-Aligning Radioisotope Elution System - A radioisotope elution system including a radioisotope generator having an alignment structure. The alignment structure may be configured to interface with a complementary alignment structure of an auxiliary radiation shield assembly. | 10-29-2009 |
20120187308 | RADIONUCLIDE GENERATOR AND METHOD OF STERILIZATION - A column assembly of a radionuclide generator includes a column that retains a parent radionuclide that spontaneouosly decays to a relatively short-lived daughter radionuclide. A fluid path extends from an inlet port to the column and then to an outlet port and allows daughter radionuclide to be eluted from the radionuclide generator for use. Improved retention of parent radionuclide in the column is accomplished by preventing fluid from entering the flow path in a liquid state, such as during sterilization. Proper column chemistry is also promoted by preventing excess moisture from coalescing in the column, which may promote a higher and/or more reliable yield of daughter radionuclide from a radionuclide generator. | 07-26-2012 |
20120298880 | Self-Aligning Radioisotope Elution System and Method - A radioisotope elution system including a radioisotope generator having an alignment structure. The alignment structure may be configured to interface with a complementary alignment structure of an auxiliary radiation shield assembly. | 11-29-2012 |
20120305800 | Holder and Tool For Radioisotope Elution System - A holder for a vial containing a sterile liquid for use with a radiopharmaceutical elution system includes a holder body. The body has a top, an opposing bottom, an opening in the top and a vial chamber. The vial chamber extends from the opening in the top toward the bottom and is sized and shaped for receiving the vial therein. An access opening extends through the bottom to the vial chamber and is aligned with a septum of the elution vial when the sterile vial is received in the vial chamber. A cap is removably secured to the top of the holder body for selectively opening and closing the vial chamber. The holder body includes plastic and has a density less than the density of the cap. | 12-06-2012 |
