Testing which is the fitter position sensor for a cyclotron liquid target.
The [(18)F]FDG has 109.7 min half-life, there is a period about 6 h between the beginning of [(18)O]H2O irradiation until the PET-CT exam. Any fail in production chain will result in delay to the PET-CT exam. The absence of the position signs from [(18)O]H2O target valve may result in (18)F production loss. Three types of position sensors were tested. After finding the fitter sensor it was possible to reduce the incidence of fails, increasing the reliability in [(18)F]FDG production chain.
