| Abstract: | In response to the demand for PET medical radionuclides in nuclear medicine diagnosis and treatment, China Institute of Atomic Energy is conducting research on the industrialization of PET medical small cyclotrons. Magnetic field measurement and shimming is the key point in the production of cyclotrons. The compact structure of small cyclotron is a difficulty to realize the full automatic control of magnetic field measuring instrument and solving the problems of high processing cost and long cycle of conventional shimming method is the key to industrialized production. This article will introduce in detail the development of a fully automated magnetic field measurement and precision shimming platform for small cyclotrons. Through the magnetic field measurement and shimming practice of multiple small cyclotrons, a set of rapid magnetic field measurement and shimming procedures will be developed to realize fully automatic measurement method to shorten the magnetic field measurement cycle and reduce the time of shimming by precision shimming algorithm. Under the condition of ensuring high efficiency and high quality of magnetic field measurement and shimming, the time and the processing cost are greatly reduced, which lays a foundation for the industrialized production of small cyclotrons. At present, the China Institute of Atomic Energy has completed the commercialization of several small cyclotrons. |
