Problems solved by technology

[0003] At present, the state of radioactive sources is generally in a liquid state. However, due to the fluidity of liquid radioactive sources, the use of radioactive sources for state detection of medical instruments (such as quality inspection of PET) has problems such as complex operation and difficult control.

preparation example Construction

[0040] The embodiment of the present invention provides a kind of preparation method of radioactive source, refer to figure 1 , is a flow chart of a radioactive source preparation method provided by an embodiment of the present invention. The radioactive source preparation method specifically includes:

[0041] S101: Obtain a preset dose of radiopharmaceutical, wherein the half-life of the radiopharmaceutical is shorter than a preset threshold.

[0042] Due to the high cost of radioactive sources prepared from radiopharmaceuticals with long half-lives, there are strict radiation protection requirements for storage space. Therefore, the embodiment of the present invention restricts the selection of radiopharmaceuticals, that is, radiopharmaceuticals with a half-life shorter than a preset threshold are used, and radiopharmaceuticals with a half-life shorter than 7 days are usually selected, for example 18 F-FDG (Chinese: Fluorine 18F deoxyglucose; English: 18 F-fluorodeoxy-gl...

Abstract

The invention discloses preparation and a relative preparation method of a radioactive source, the radioactive source and a PET system. The preparation method of the radioactive source comprises the steps that a radioactive drug of a preset dosage is obtained, wherein the half-life period of the radioactive drug is shorter than a preset threshold value; the radioactive drug and a preset solution are mixed to obtain a mixed solution; a shaping substance is utilized to shape the mixed solution into a solid radioactive source in a preset shape. By means of the preparation method, the solid radioactive source is prepared, the shape of the solid radioactive source meets the requirements of a user, and the solid radioactive source is conveniently used in fields such as PET quality testing, PET correction factor acquisition and PET calibration.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a radioactive source preparation method, a PET quality inspection method, a PET correction factor acquisition method, a PET calibration method, a radioactive source, and a PET system. Background technique [0002] The radioactive source is prepared from radiopharmaceuticals, and the data collected by the radioactive source on the nuclear medicine equipment can be used for state detection, system calibration and correction factors of the nuclear medicine equipment. For example, positron emission computed tomography (English: Positron Emission Computed Tomography, referred to as: PET) equipment needs to use radioactive sources for quality inspection before leaving the factory. In addition, it is also necessary to use radioactive sources for periodic quality inspection in daily use. check. [0003] At present, the state of radioactive sources is generally in a liquid state. However, ...
