    摘要: A method of purification for recycling of gallium-69 isotopes includes processes of proton irradiation and dissolution for a silver alloy plating target with gallium-69. After the proton irradiation and dissolution, a high concentration elution liquid of gallium-69 and germanium-68 is obtained by washing through an ion-exchange resin to filter out gallium-69 solution, followed by neutralizing precipitation, drying, and sintering treatments to obtain a gallium oxide. The gallium oxide can be dissolved to produce a solid target, and the washing processes can be repeated. The solid target after use can be placed in recycling again. This method is not only implemented to reduce the cost of production and comply with recycling notion nowadays, but also enhance efficiency in the practical application of radioisotopes.

    摘要: An automatic radiopharmaceuticals filling machine mainly comprises a main unit with an activation mechanism to perform three-dimensional reciprocal movement. The activation mechanism has a lateral slider that can be activated to move reciprocally along lateral X-axis. On the lateral slider, there is a vertical slider that can extend perpendicularly and move reciprocally along lateral Y-axis. An injection needle is located on the vertical slider and can be activated to move reciprocally along Z-axis perpendicular to the lateral slider. A syringe rack is located in the moving range of the injection needle to accommodate a plural number of syringes, on each of which there is an injection hole. A drug pump has an inlet and an outlet. The inlet connects to a high-dose radiopharmaceuticals drug bottle. The outlet connects to the injection needle. The drug pump withdraws the radiopharmaceuticals from the drug bottle to the injection needle and allows the front end of the injection needle activated to go through the injection hole into the syringe and fill the radiopharmaceuticals into the syringe.

First and second conductive strips are formed. First and second insulating layers are formed over the first and second conductive strips. Plug contacts and fuse plugs are formed through the first and second insulating layers to the first and second conductive strips. A third insulating layer is formed over the second insulating layer. Metal lines are formed over the third insulating layer in the device area. A fuse via opening is formed in the third insulating layer. A plug fuse is formed in the fuse via opening. A fourth insulating layer is formed over the plug fuse and the third insulating layer. A fuse opening is formed at least partially though the fourth insulating layer over the fuse area.
