Abstract

The invention discloses a sealed radioactive source and a preparation device and method thereof. The sealed radioactive source comprises an airtight bag shell and a radioactive substance contained inthe airtight bag shell, and the airtight bag shell comprises two interfaces which can be open and closed. The preparation device comprises a mixed liquid circulating pipeline and a circulating power component, the mixed liquid circulating pipeline comprises two bag shell interfaces and at least one drug interface, the two bag shell interfaces are used for being detachably and hermetically connected with the two interfaces on the airtight bag shell respectively to enable the inside of the airtight bag shell to be communicated with the mixed liquid circulating pipeline, the drug interface is used for guiding radioactive drug in at least one external radioactive drug container into the mixed liquid circulating pipeline, and the circulating power component is used for providing circulating power into the mixed liquid circulating pipeline. The preparation device prepares the sealed radioactive source in a fully automatic manner and does not need participation of operating personnel, so thatradiation risk of the operating personnel is lowered, and the radioactive source prepared by the device is uniform in activity.

Description

technical field [0001] The invention relates to nuclear medicine technology, in particular to a sealed radioactive source, a preparation device and a preparation method for the sealed radioactive source. Background technique [0002] PET (positron emission tomography, positron emission tomography) is the most important imaging equipment in the field of nuclear medicine. PET equipment can include tens of thousands of independent detectors, and the performance of each detector will be affected by temperature, voltage, and itself over time. Drift occurs due to factors such as lifespan. In order to monitor and correct the influence of detector drift on the performance of PET equipment, in actual work, the user of PET equipment needs to use various radioactive standard sources to calibrate the PET equipment. Among these radioactive standard sources, the most commonly used is the barrel-shaped radioactive source with uniform activity. [0003] At present, there are two ways to o...
