Clinical Ion Beam Applications: Basic Properties, Application, Quality Control, Planning

摘要

Heavy-ion therapy using beam scanning and biological dose optimization is a novel technique of high-precision external radiotherapy. It yields a better perspective for tumor cure of radio-resistant tumors. However, heavy-ion therapy is not a general solution for all types of tumors. As compared to conventional radiotherapy, heavy-ionradiotherapy has the advantages of higher tumor dose, improved sparing of normal tissue in the entrance channel, a moreprecise concentration of the dose in the target volume with steeper gradients to the normal tissue, and a higherradiobiological effectiveness for tumors which are radio-resistant in conventional therapy. These properties make itpossible to treat radio-resistant tumors with great success, including those in close vicinity to critical organs.
