Due to the physical properties of protons and carbon ions, radiation that passes through the patient’s body practically does not damage healthy tissues and concentrates on the destruction of the tumour. Proton/ ion beam therapy is, therefore, best suited for treating oncology of radiation-sensitive organs – the brain, spinal cord, eyes, liver and lungs.
The biological efficiency of carbon ions is about three times higher than that of protons. Ion beam therapy is particularly suitable for the treatment of bone and soft tissue cancers, slow-growing tumours, tumours adjacent to radiation-sensitive organs, oxygen-poor malignancies or local relapses after conventional radiation therapy.
The decisive factor in proton therapy is the exact location of the patient. For this purpose, MedAustron uses the world’s first robotic ceiling positioning system specially developed for the medical field. This system allows patients to be positioned with an accuracy of up to half a millimetre and ensures that the patient remains in this position throughout the treatment. The robot can move in seven independent directions. Also, the treatment table can be rotated and tilted. The patient’s position is checked 500 times per second. In this way, the procedure’s accuracy is assured.
