Estimation of carbon ion induced activity distributions with the yield approach

Phantom irradiation with pencil-like beams of carbon ions have been performed at GSI Darmstadt. The induced β⁺-activity has been monitored by means of the dedicated in-beam PET scanner mounted at the irradiation site. On the basis of the yield approach ion beam induced positron emitter distributions have been predicted for these irradiation and activity distributions have been estimated. The comparison of predicted and measured activity profiles provides promising results.
