The CyberKnife has a unique patient table and
positioning system called RoboCouch. During treatment with CyberKnife,
the RoboCouch moves the patient slightly to allow the CyberKnife the
best angle to treat the tumor.
The linear accelerator is the part of the
CyberKnife that delivers beams of high-energy radiation to the tumor
with sub-millimeter (within the width of a hair) accuracy.
The high precision robotic manipulator
positions the linear accelerator in almost any direction providing
extremely accurate radiation delivery.
During a CyberKnife treatment low-energy x-rays are
constantly being taken to track the tumor position and to adjust the
position of the linear accelerator accordingly to spare healthy tissue
surrounding the tumor.
Floor Image detectors
The floor mounted image detectors
capture high-resolution anatomical images from the x-ray throughout the
treatment. These live images are continually compared to previous images
to determine real-time patient positioning and target location. Based
on this information, the robotic manipulator instantly adjusts for any
