The CyberKnife® Radiosurgery Solution: Early stage Lung Cancer
Increased Dose of Radiation
Due to its unique tumor tracking capability, the CyberKnife® device has a published accuracy of one millimeter (14), with a much sharper dose fall off at the target volume margin compared with “standard radiation,” effectively rendering the high dose radiation margin more “scalpel-like.” This allows a far smaller normal tissue expansion around the cancer, resulting in much better sparing of critical adjacent tissues from the high dose volume, allowing a substantial radiobiologic dose increase to the cancer (12).
