Front profile of the product Elektra Esprit.


Radiosurgery is a therapeutic radiation technique that applies a field of radiation using multiple, focused, finely collimated radiation beams with surgical precision in a single session. This noninvasive alternative to surgery typically improves patient quality of life both during and after treatment. It is virtually pain-free, requires little to no anesthesia, has minimal side effects and is usually performed as an outpatient procedure. Patients typically return to pre-surgery activities within several days.

Stereotactic Radiosurgery

Stereotactic radiosurgery (SRS) is a non-invasive procedure that employs highly precise radiation delivery techniques to treat brain disorders like tumors, AVM, and certain functional diseases. In cases where it is used to address regions of the body other than the brain, it is also referred to as stereotactic body radiation therapy (SBRT) or stereotactic ablative radiation therapy (SABR).

There are three main technologies typically used to deliver SRS treatments, including:

  • Gamma Knife
  • Linear Accelerator (Linac) with SRS capability
  • Proton Beam Therapy

SRS is increasingly being utilized as a substitute for other therapies in the treatment of cancer and neurological disorders. With Elekta’s cutting-edge advancements in radiosurgery, your treatment team can rely on having the appropriate solution to meet the increasing demand for efficient and personalized care.
