Abstract:
Prompt gamma rays are a kind of secondary radiation produced in particle therapy, and prompt gamma information largely reflects the incidence of particles. Consequently, use of prompt gamma information to verify the range of particles is a promising verification method. In this article, the concept of prompt gamma ray in vivo range verification and the advantages of prompt gamma verification over existing methods were introduced. Secondly, the progress in developing a method for range verification using prompt gamma in recent years was reviewed, and the advantages and disadvantages of three methods including prompt gamma imaging (PGI), prompt gamma timing (PGT) and prompt gamma spectroscopy (PGS) were discussed. Finally, these three methods were summarized, and the development trend of prompt gamma rays for in vivo range monitoring was prospected.
