Embodiment Construction
[0031] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0032] In the first aspect of the embodiments of the present invention, the embodiments of the present invention provide a device for preparing a radiation source phantom, such as figure 2 As shown, the radioactive source is a radiopharmaceutical contained in a bottle body 103, and the bottle body 103 has a sealing cap for sealing the mouth of the bottle body 103;
[0033] The bottle body 103 containing the radiopharmaceutical is installed in the radioactive source phantom preparation device, and the radiopharmaceutical 18F-FDG in the bottle body 103 gradually dissolves with the action of a liquid solvent (such as water) until it is mixed uniformly, and the obtained Liquid radioactive sources used between PET equipment.
[0034] The preparation device include...

The invention relates to a preparation device for a radioactive source phantom. The radioactive source is a radiopharmaceutical contained in a bottle body, and the bottle body has a sealing cover for sealing the mouth of the bottle body. The preparation device includes a power assembly, a source The barrel and the liquid circulation pipeline also include a first needle tube and a second needle tube for forwardly penetrating through the sealing cover to be inserted into the bottle; the first needle tube and the second needle tube pass through the water inlet and outlet pipe structure and the water outlet pipe Connection; the water inlet and outlet pipe structure is located in the cavity of the needle seat extension structure of the needle seat of the radioactive source, and the needle seat is used to fix the bottle body. The operator fixes the radioactive source to the needle hub by holding the needle hub extension, and then inserts the needle tube into the vial. The beneficial effects of the present invention are: the connection between the radioactive source and the preparation device is more convenient, time-saving and labor-saving; and through the design of the needle base extension structure with adjustable length, the distance between the operator and the radiopharmaceutical is increased, and the impact of the radioactive source on the operator is reduced. of radiation.
Description
technical field [0001] The invention relates to the fields of preparation of medical liquid radioactive sources and radiation protection, in particular to a preparation device for a radioactive source phantom. Background technique [0002] Fluorodeoxyglucose, whose chemical name is 2-fluoro-2-deoxy-D-glucose, usually abbreviated as 18F-FDG, is currently the main imaging agent for PET-CT imaging. 18F-FDG and water solvent are uniformly mixed in a plastic container to form a liquid radiation source phantom, which is used for PET-CT quality inspection and calibration. The current common way to prepare liquid radioactive sources is: manually add 18F-FDG into a plastic container containing water solvent, and then shake the container to mix the 18F-FDG evenly. In this preparation process, the operator is in close contact with the radioactive source 18F-FDG throughout the whole process, and radiation protection is relatively difficult. Although the automatic liquid radioactive so...
