Stereotactic Radiosurgery (SRS/SBRT): Image Guided Radiation Therapy (IGRT) - is the process that utilizes frequent or dynamic imaging of the patient and treatment area to more precisely direct radiation therapy. The use of various imaging devices allows coordination of the actual radiation treatment plan with the patient's actual position. Demonstration of a lung treatment using IGRT.
Radiation Simulation Units: The simulation units are used to obtain patient and organ landmarks to use in the creation of atreatment plan by the radiation oncologists. Simulation rooms contain X-ray machines that look similar to a linear accelerator or they can be CT scanners that allow slice information to be used for contouring the area of interest.
