Stereotactic Radiosurgery (SRS)
A method of performing virtual surgery for certain tumors of the brain. High-frequency X-rays are used to virtually reach inside a patient and precisely target and kill the tumor without the need for anesthesia. The patient does not feel anything during the treatment and treatment is usually delivered in a single 30-minute session.
Stereotactic Body Radiation Therapy (SBRT) also called SABR
A method of precisely targeting tumors using high energy X-rays and extremely accurate tumor positioning to allow tumors to be killed in just 5 treatments. This method can be used in small tumors throughout the body.
Intensity Modulated Radiation Therapy (IMRT)
A radiation therapy treatment technique which allows the shape and intensity of the radiation to be changed during treatment in order to precisely focus the radiation on the tumor target and spare more of the surrounding tissue. This allows for better dose distribution to the tumor while minimizing the dose to healthy organs.
Image Guided Radiation Therapy (IGRT)
An enhanced radiation therapy treatment using computers and a linear accelerator to pinpoint the exact location of a tumor while the patient is in the treatment position. This allows the radiation oncologist to adjust the radiation beam based on the position of the targeted tumor and critical organs before delivering the treatment.
External Beam Radiation Therapy (EBRT)
EBRT is a high-energy radiation that is directed to a localized area. The beam is created in a machine called a linear accelerator and directed through the skin to the cancer. During treatment, the patient lies on a table. Radiation is typically administered in small doses over the course of several weeks.
Three-Dimensional Conformed Radiation Therapy (3D-CRT)
A type of EBRT, 3D-CRT uses state-of-the-art computers in conjunction with CT scans to create a digitally constructed 3-D image of the tumor and surrounding normal tissue. Radiation oncologists can then shape and direct the treatment field more precisely to better target the cancer and spare the normal tissue, thereby reducing radiation side effects.
Prostate Seed Implant
A method of treating prostate cancer that involves a single day treatment to place seeds directly in the prostate to kill prostate cancer. During prostate seed implant treatment, radioactive seeds of Iodine 125 are inserted directly into the prostate under general anesthesia. The patient usually stays in an observation bed for several hours after the procedure and is sent home the same day. This technique has been shown to provide a better chance of cure in patients with high-risk prostate cancer in a recent randomized trial.
Frequency of Radiation Treatments
The Radiation Oncologist will determine the duration of your radiation therapy. Treatments are generally administered five days a week at a time that is convenient for the patient.
