Prediction of β⁺-activity distributions from PT-PET by means of a yield approach

Particle therapy PET (PT-PET) is a clinically approved method for the verification of ion beam therapy. The evaluation of the obtained images is based upon the comparison of the measurement and a prediction. A new approach for the simulation of the activity distribution using measured yields in reference materials has recently been published. This approach provides the possibility to take the elemental composition of the different tissues into account. In this work first results of simulation in real patient cases are presented.
