How Does it Work?
Concentrated beams of radiation are administered from different targeting positions and angles using a linear accelerator (LINAC) mounted on a robotic manipulator. All of the beams intersect and converge within the tumor or lesion where the cumulative radiation dose is high enough to destroy the cancer cells and stop the growth of active tissue. During the entire treatment the location of the tumor is continuously monitored using X-rays and image-guided cameras. These images are instantly compared to the digitally reconstructed radiography produced from the initial CT scan, allowing the robotic system to reposition the radiation source before the delivery of each beam.
