Abstract
The present invention provides a positron source essentially consisting of a carbon member having 18F bound onto the surface thereof, a method of a preparing the same, and an automated system for supplying the same. In the present invention, the positron source is prepared by irradiating a solution 35 containing both H218O and a small amount of natural fluorine ions with a beam of charged particles to generate 18F, and then passing an electric current through the solution 35 using a carbon member 40 as an anode to cause to bind the generated 18F onto the surface of the carbon member 40.
