CyberKnife: No Gating or Breath Holding - Radiation Therapy
Tumors in the lungs, liver, pancreas, kidney, prostate and more, can move as much as two inches with every breath. These movements often occur because of normal breathing or other regular bodily functions, such as the passing of gas or filling of the bladder. When treating such tumors with radiation therapy, it can be difficult to accurately target these tumors without damaging surrounding tissue and organs.
There are techniques employed to help to minimize these movements during treatment.
