Stereotactic radiosurgery delivers a high dose of radiation, generally in one treatment. For brain surgery, SRS generally requires the use of a stereotactic frame that is fixed onto the patient's skull. The CyberKnife system allows physicians to perform SRS procedures without the use of a stereotactic frame, which can be less traumatic and less painful for the patient.
a high dose of radiation given in one treatment; uses a precisely aimed, highly focused radiation beams and stereotactic localization to target a specific area.
Stereotactic Radiosurgery (SRS) is a one-day, single treatment, outpatient procedure that delivers a focused dose of radiation to the target. With this treatment, the lesion location is determined by MRI scans and /or CT scans, a 3-D treatment plan is established, and then multiple precisely-guided radiation beams from the LINAC equipment treat the tumor in a single treatment. A SRS procedure is completed in a few hours and actual dose administration time is typically less than 45 minutes. Currently, SRS is appropriate for a variety of malignant and benign brain tumors as well as other brain disorders. When this same equipment and process is used to deliver a similarly accurate treatment in multiple fractions over several days it is called Stereotactic Radiotherapy.
The use of external radiation sources either from a linear accelerator (X-knife), or a special Cobalt-60 (Gamma Knife) irradiator to deliver many small beams of radiation, all focused onto an internal structure, such as a brain tumor.
A pinpoint-fine radiation laser is used to attack the cancer. Because the laser is so fine, doctors can avoid "hitting" surrounding, healthy tissue. Doctors, therefore, are able to use higher doses of radiation without worrying about the long-term side effects it may have on adjacent tissue. This is particular important for cancers in the head and neck area and for pediatric patients.
This term refers to a class of procedures that accurately deliver a high dose of radiation, in one to five treatment sessions. SRS typically uses a stereotactic frame that is anchored to the patient's skull for targeting and immobilization. In contrast, the CyberKnife allows physicians to perform SRS without a stereotactic frame, which makes this procedure significantly less traumatic and painful for the patient.
The precise delivery of radiation to a preselected stereotactically localized target.
This service permits us to aim the radiation beam from the linear accelerator with stereotactic precision for the treatment of deep arteriovenous malformations, malignant and some benign tumors, and otherwise inoperable or difficult to reach lesions.
A technique used to treat various brain diseases by concentrating radiation very accurately within a small volume of the brain
A non-invasive modality that precisely delivers focused, multiple beams of radiation to areas where they're needed–a single point on a tumor site–while avoiding healthy tissue.
A radiation therapy technique that uses a large number of narrow, precisely aimed, highly focused beams of ionizing radiation. The beams are aimed from many directions circling the head, and meet at a specific point.
A radiation therapy technique using a large number of narrow, precisely aimed, highly focused beams of ionizing radiation. Beams meet at a specific point being aimed from many directions. Usually only one treatment at high dose is planned.
Stereotactic external-beam radiation.
this new treatment method focuses high doses of radiation at a tumor while limiting the exposure that normal tissue receives. The treatment may be useful for tumors that are in places where regular surgery would harm essential tissue, for example, in the brain or spinal cord, or when the patient's condition does not permit regular surgery.
A highly precise form of radiation therapy that directs narrow beams of radiation from different angles at a brain tumor or abnormality. Using a device that keeps the head completely still, this treatment minimizes the amount of radiation to healthy brain tissue. Also see stereotactic radiotherapy.
A radiation therapy technique involving a rigid head frame that is attached to the skull; high-dose radiation is administered through openings in the head frame to the tumor while decreasing the amount of radiation given to normal brain tissue. This procedure does not involve surgery. Also called stereotaxic radiosurgery.
