Prompt-Gamma-Imaging: Clinical application demonstrates potential for online-adaptive proton therapy

Treatment verification in proton therapy is important for 1) detecting anatomical changes during treatment 2) independent quality assurance during online-adaptive proton therapy (OAPT) and, hence, 3) potentially reducing safety margins. In this context, clinical Prompt-Gamma-Imaging (PGI) data were evaluated which demonstrated the potential of PGI for treatment verification.
