18F-dodecane positron imaging agent and preparation method thereof

Abstract

The invention discloses an < 18 > F-dodecane positron imaging agent and a preparation method thereof, is based on a positron nuclide chemical labeling method, and belongs to the field of industrial nondestructive testing. The invention discloses an < 18 > F-dodecane positron imaging agent and a preparation method thereof in order to overcome the defects of an existing marking scheme in accuracy and application range, so that the < 18 > F-dodecane positron imaging agent can determine that gamma photons are generated by burning kerosene instead of volatilized kerosene, the marking accuracy is realized, and the reliability is improved; secondly, the application range of the 18F-dodecane positron imaging agent is not only kerosene, but also can be used for detecting gasoline and aerospace kerosene, so that the application range of the 18F-dodecane positron imaging agent is expanded, and the applicability is improved; meanwhile, the finished product is subjected to structure confirmation and quality control experiment in the preparation process, so that the quality and accuracy of the < 18 > F-dodecane positron imaging agent are ensured.

Description

technical field [0001] The invention relates to the technical field of industrial non-destructive testing, in particular to a 18 F-dodecane positron imaging agent and preparation method thereof. Background technique [0002] C.D.Anderson et al. first observed positron tracks in cosmic rays using cloud chambers in 1932; after that, related theoretical and applied research on positrons has been developed by researchers for nearly a century. Many branches of science; gamma photons are tomographic techniques for imaging particles whose source is produced by the annihilation of positrons. Positrons have the same mass as electrons, and the amount of positive charge equal to the negative charge of electrons, making them an antimatter particle. [0003] At present, the conventional artificial preparation method of positron is to use a cyclotron to continuously bombard the target element in a specific compound with a hydrogen anion (H-) source or a deuterium anion (D-) source as th...

AI Technical Summary

Problems solved by technology

[0006] At present, there are still some deficiencies in the existing labels: (a) indirect labeling, after the labeling, due to the volatility of kerosene during detection, it is impossible to judge whether the gamma photons are produced by volatile kerosene or burning kerosene , thus affecting the follow-up judgment and the next step of work; (b) this type of imaging agent can only be used for aviation kerosene marking detection, and its application is not wide
