The versatile Trilogy system delivers 3D conformal radiotherapy, IMRT, stereotactic radiosurgery, fractionated stereotactic radiation therapy, for cancer and neurosurgical treatment.

Three-dimensional (3D) conformal radiotherapy utilizes special imaging techniques to define the size, shape and location of the tumor as well as normal tissue. Your radiation oncologist can precisely design the radiation beams to the size and shape of your tumor while avoiding normal tissue using the multi-leaf collimator.

Intensity Modulated Radiation Therapy (IMRT) is a specialized form of 3D Conformal Radiotherapy in which the radiation dose is delivered using small “beamlets.” The intensity of each beamlet can be optimized to create a customized treatment plan based upon your specific needs. For some treatments image guidance may be used localize the tumor immediately before treatment delivery.

Stereotactic Radiosurgery

Stereotactic Radiosurgery or SRS is the most precise method of external beam radiation. The beams are shaped to match the contours of the tumor and are delivered from many different angles around the body. The intersecting beams deliver an intense dose of radiation only to the affected site while safely avoiding nearby healthy tissue. In this way, SRS provides a non-invasive alternative to surgery, allowing treatment of some otherwise inoperable tumors. With SRS the full radiation dose is delivered in a single outpatient session.

Stereotactic Radiation Therapy

Stereotactic Radiation Therapy or SRT is delivered over a short course of multiple treatment sessions. SRT is also known as fractionated radiosurgery. The full radiation dose is delivered over a short course of multiple treatment sessions. SRT is used to treat tumors or abnormalities in the brain, head, neck and spine. It may also be used to treat tumors in other parts of the body.
