North Shore-LIJ Center for Stereotactic Radiation Therapy

Stereotactic Radiosurgery, Radiotherapy and Radiation Therapy

North Shore-LIJ Health System is proud to introduce the North Shore-LIJ Stereotactic Radiation Center located at North Shore University Hospital. This program uses the Novalis system, a state-of-the-art radiation delivery technology used for those undergoing stereotactic radiosurgery or stereotactic radiotherapy.

What Is Stereotactic Radiation?

Stereotactic radiation therapy is a non-invasive delivery of high doses of radiation therapy to a small target in a single (or up to five) treatment. Its exquisite precision allows for the protection of surrounding normal tissue. Although called radiosurgery, there is actually no incision and it is performed on an outpatient basis. SRS uses radiation to shrink or control the growth of a tumor by killing or halting the growth of tumor cells. 

The Stereotactic Radiation Center at North Shore University Hospital

Stereotactic radiation can be delivered using a number of different technologies. At North Shore University Hospital in Manhasset, we use the Novalis®  robotic technology, also referred to as “shaped beam surgery.” Novalis® continuously shapes the treatment beam to match the size and shape of a tumor from all angles. This allows for the best targeting of the tumor while protecting healthy tissue. Shaping the beam to the exact dimensions of the tumor is the latest and most technologically advanced approach for treatment with stereotactic radiosurgery.

The procedure, which is done on an outpatient basis, is virtually painless and the patient remains awake for the entire procedure. In most cases, patients undergo treatment in the morning and can return to their normal routine by the afternoon.


  • Stereotactic radiosurgery (SRS) is the non-invasive delivery of a precise high-energy radiation to a tumor or lesion of the brain or spine.
  • Stereotactic body radiotherapy (SBRT) involves the same type of radiation treatments as radiosurgery, but is delivered to targets elsewhere within the body, such as the lung, liver, prostate or other sites.
  • Shaped beam surgery is the most advanced approach to SRS or SBRT available today. The Novalis® system continuously shapes the treatment beam to match the size and shape of a tumor from all angles, ensuring that the tumor receives the full prescription dose of radiation, while protecting healthy tissue.
