Monitoring of Ion Beam Energy by Tracking of Secondary Ions: First Measurements in a Patient-like Phantom

Popis výsledku v původním jazyce

Due to the finite range of ions in matter and the presence of the Bragg-peak, ion beams provide highly localized dose distributions. In radiation therapy with ion beams, unpredictable changes within the patient can deteriorate the quality of the dose distribution in the target. Therefore it is desired to monitor the beam within the patient in a non-invasive way. In this contribution the information carried by secondary ions, which are emerging from a patient during carbon ion beam irradiation, is studied. In a framework of investigations on the feasibility of beam monitoring exploiting secondary ions, the aim of this study was to show the possibility of distinction of two different primary carbon ion beam energies solely from the analysis of the secondary ion directions measured. The situation was complicated by realistic tissue inhomogeneities simulated by using a patient-like phantom. Experiments were performed at the Heidelberg Ion Beam Therapy Center in Germany using narrow carbon
