CyberKnife® Radiosurgery:
Precise Ablation of Focal Kidney Lesions
The kidney is another organ that moves with respiration, limiting the accuracy of conventional or even stereotactic radiotherapy approaches against malignant parynchemal renal lesions, resulting in a large fuzzy margin between the high dose and low dose radiotherapy zone. CyberKnife® Synchrony® respiratory tracking system overcomes this problem by locking onto implanted gold fiducial markers that are easily placed within the kidney under CT guidance, and correlates their position with the respiratory cycle as determined by optical tracking, tracking the targeted lesion with 1.5 mm accuracy throughout the entire breathing cycle. This allows a much smaller applied margin compared with other radiation delivery systems – virtually surgical in its precision.
