Ion Beam Radiotherapy
During the heavy ion therapy project GSI, we contributed to the development of patient positioning, treatment planning and dosimetry, which were then employed for patient treatments from 1997 - 2008. During this time many physical, biological (Experimental radiobiology of ion beams) and clinical investigations have been performed. The developments in medical physics have been transferred to the Heidelberg Ion Beam Radiotherapy Center (HIT), which started clinical operation in 2009. The experience gained at GSI is also incorporated into scientific and educational courses on ion beam radiotherapy and as well as into radiation protection trainings.
