At the ion therapy and research centre MedAustron in Wiener Neustadt, Austria, patients benefit from an innovative form of radiation therapy. Ion beam therapy uses charged particles for irradiation – protons or carbon ions. The special physical properties of these particles allow the provider of the treatment to apply the maximum radiation dose to the exact area of the tumour, while mostly sparing the healthy tissue. Thus, this form of therapy is optimal for treating tumours close to radiation sensitive organs and therefore side effects and long-term effects can be significantly reduced. Ion beam therapy offers an additional option for cancer treatment.
