Stereotactic Radiosurgery | Trilogy Radiosurgery
Stereotactic Radiosurgery (SRS) Trilogy is the most versatile Stereotactic Radiosurgery technology that exists today. Unlike other radiosurgery platforms, Trilogy offers image-guided technologies via its on-board imager, together with sub millimeter precision. The physicians at Advanced Radiation Centers are leaders in the treatment of tumors of the brain and spine using Stereotactic Radiosurgery with the Trilogy SRS system.
What is Stereotactic Radiosurgery (SRS)?
Stereotactic Radiosurgery, or SRS, is a non-invasive medical procedure, which uses highly focused beams of radiation to treat various benign and malignant conditions. Advanced Radiation Centers is proud to be the first site on Long Island to have a Trilogy Stereotactic Radiosurgery Linear Accelerator, a highly advanced technology for the treatment of tumors. Stereotactic Radiosurgery is a cancer-fighting technique, which utilizes very small and highly directed radiation beams to target tumors within the brain and spine and other sensitive areas of the body.
The word, Stereotactic, or “stereotaxy” comes from the Greek word meaning movement in space. This technique makes use of a three-dimensional coordinate system to locate small targets inside the body in which to perform some action using radiation or surgery. For example, if not using radiosurgery, neurosurgeons can use stereotactic surgery to target and remove or biopsy lesions within the brain. Stereotactic Radiosurgery is used primarily to treat cancers or benign lesions in the brain, spine and central nervous system. Since lesions in the brain are immediately adjacent to very delicate and important nerves and sensitive tissue, this procedure allows the Radiation Oncologists at Advanced Radiation Centers to use “pencil-thin” beams to target lesions using specialized high-precision radio surgical devices to deliver high dose radiation with sub-millimeter accuracy.
By using Stereotactic Radiosurgery, higher doses of radiation can be given with each treatment since the threat of collateral damage to neighboring tissues is minimized. The precision of SRS treatments with Trilogy is unmatched. Its pinpointed technology allows the cancer-destroying doses of radiation to zero in on a tumor within a very small area, while leaving normal tissue right next to it virtually untouched. SRS is very effective for treating tumors of the brain, spine, and other parts of the body, especially those near sensitive tissue.
What Technologies are used for SRS at Advanced Radiation Centers?
How does Trilogy SRS stack up to other radiosurgery technologies?
The power of Trilogy yields shorter treatment times, making the experience more comfortable for the patient. Trilogy SRS is the only system that exists, which provides the ability to deliver SRS, IMRT, IGRT or DART radiation therapies. Combined with RapidArc Volumetric Arc technology, Trilogy SRS provides the most powerful and precise form of Stereotactic Radiosurgery that exists in any linear accelerator-based or non-based system.
Trilogy SRS provides the Radiation Oncologist further benefits compared to other radiosurgical devices including:
• A specialized Radiosurgery dose rate of up to 1000mu/min for efficient SRS delivery. This means that treatment is delivered faster, which
increases patient comfort.
• 2D and 3D KV image guidance for higher quality imaging at lower doses.
• Full 360° range of treatment delivery angles with positional couch angles.
• Stereotactic frame or frameless immobilization for patient positioning to treat any area of the body.
• Real-time Position Management™ (RPM) system – for gating perfectly timed beam delivery with minimal margins.
• Portal Dosimetry IMRT treatment delivery verification.
• Dynamic high resolution MLC for exquisite beam sculpting.
• Delivery verification and quality assurance in Argus Linac and Argus IMRT quality assurance software.
• Highest dose rate for shorter sessions.
• Tight isocenter alignments on all three axes. Targets the smallest lesions.
• Rapid on-board imaging. Reposition patients quickly and accurately.
• Cone-Beam CT, fine tune patient set ups with ultra-precise CT scans.
Can other parts of the body be treated with Trilogy-SRS?
What types of Brain Tumors can be treated with Trilogy-SRS?
These tumors include:
Glioblastomas (Glioblastoma Muliforme)
Metastatic Tumors that have spread to the brain from originating:
Other types of cancers
In addition, certain benign diseases can be treated with Trilogy SRS including:
Is anyone with a brain tumor a candidate for Trilogy?
Why would Trilogy-SRS be used to cure rather than Surgery?
What is the process when undergoing Trilogy SRS at ARC?
The highly precise radiation beams are targeted to the lesion, or area of risk within the brain by the Radiation Oncologist based on images, such as CT, MRI or angiography of the brain and body. The radiation is applied from an external source, under precise mechanical orientation by a specialized apparatus. Multiple beams are directed (collimated) and centered at the intracranial or extracranial lesion to be treated.
