Fractionated Stereotactic Radiosurgery - Uses highly focused radiation produced by a linear accelerator to deliver treatment precisely to a tumor in three to five sessions. This technique is used for tumors that are too large for Gamma Knife radiosurgery. It can also be used for some tumors outside of the brain and skull, such as tumors of the lungs and spine.
Fractionated Stereotactic Radiotherapy - Uses a lower dose of radiation but is still able to create a 3-D image of the area. Several lower-dose radiation beams are arranged precisely to the shape of the area (conformal plan) and are then enhanced with computer technology to produce a 3-D image. This conformal radiation helps spare unnecessary radiation to surrounding tissue. This technique can be used for skull based tumors at a fractionated dose while protecting highly sensitive tissue surrounding the tumor.
Rapid Arc Accelerator - Decreases treatment times from two to 20 minutes by delivering the dose of radiation more effectively. This technique uses image-guided real-time CT scans (computerized tomorgraphy). This technique allows for better verification of the location of the tumor.
IMRT- Intensity Modulated Radiation Therapy- Allows for radiation dosing changes during surgery. During treatment, the intensity of the radiation can be changed to avoid injury to adjoining normal tissue and to deliver an increased dose of radiation to the tumor. IMRT also uses a conformal plan so that radiation beams are shaped to the area and then enhanced using computer technology.
