Treatment with highly accurate radiation
Thousands of radiation beams are generated with a level of accuracy better than 0.5mm. Individually, each radiation beam is too weak to damage the normal tissues it crosses on the way to the target. But when focused precisely on that target, the beams intersect and the combined radiation is sufficient to treat the targeted area.
Efficient radiation dose
The radiation damages the DNA in the cells of the tumour or other abnormality being treated, such that the cells that make up the abnormal tissue targeted can no longer reproduce. Eventually, when these cells come to the end of their natural life span, they find that they are unable to reproduce and replace themselves because the DNA essential to this process is no longer functioning properly.
