Stereotactic Radiosurgery is a form of Image-Guided Radiation Therapy (IGRT), a radiation treatment that uses advanced imaging technologies to direct radiation dose delivery to a tumor. Tumor motion including respiration-induced and other random-patient movement often prevents targeted, optimum dose delivery.

Brainlab IGRT offers clinicians advanced imaging technology to verify patient and tumor position at the time of treatment. Knowing exactly where the tumor is allows clinicians to reduce the amount of tissue irradiated, targeting only the tumor and sparing the surrounding normal tissue. Irradiating less normal tissue reduces the toxicity of radiotherapy, improves the patient’s quality of life, and may make it possible to deliver higher radiation doses to the tumor in fewer treatment sessions.

Treatment Time
Stereotactic Radiosurgery allows radiation treatment to be applied in a single session with a high dose of radiation. This is different from fractionated stereotactic radiotherapy where radiation is delivered in smaller amounts in a series of treatments over a period of time.

Short treatment times can be important for three reasons: treatment, accuracy and patient comfort. The length of treatments with some devices can be extreme, lasting an hour or more, during which the patient must lie as still as possible. Prolonged treatment times can make the entire process even more stressful, and some physicians recommend practicing meditation during the procedure or even prescribe a sedative. Reducing the treatment time also minimizes the time where the patient may make small movements that can affect the overall accuracy of the treatment.

Fast treatment delivery improves both patient comfort and treatment accuracy. Stereotactic Radiosurgery is virtually painless and does not typically require anesthesia. Moreover, as compared to conventional surgery, there is no scarring or disfigurement and little risk of infection.
