Patent ID: 6845137

Claim:
A method for preparing 18 F-Fluoride from 18 Oxygen, the method comprising the steps: obtaining molecules of 18 Oxygen in gaseous form in a chamber that includes at least one component to which 18 F-Fluoride adheres; irradiating the 18 Oxygen gas in the chamber by a proton beam through a chamber window, a portion of the proton beam passing through the chamber window and reaching the 18 Oxygen gas within the chamber having a beam current of 100 μA or more and converting a portion of the 18 Oxygen into 18 F-Fluoride, the converted 18 F-Fluoride adhering to the at least one component; and exposing the at least one component to a solvent within the chamber, the solvent dissolving the 18 F-Fluoride adhered to the at least one component while substantially maintaining a constant orientation between the chamber window and the at least one component during the irradiating and exposing steps.
