Stereotactic Radiosurgery Division


Stereotactic radiosurgery (SRS) is a unique and safe alternative to traditional brain and spine surgery for the treatment of complex and difficult neurosurgical conditions. The Brown University SRS Division at Rhode Island Hospital offers two types of SRS: Gamma Knife and CyberKnife. SRS is a non-invasive form of therapy that allows for the precision of surgery without a knife. SRS delivers precise and accurate radiation to brain lesions with a low risk of harming normal brain tissue. There is no need for an incision, eliminating the need for anesthesia, long hospital stays and long recoveries.

SRS is a highly versatile and powerful neurosurgical tool. It can be used to destroy benign brain tumors, metastatic brain tumors and arteriovenous malformations. It is also often used to treat pain conditions like trigeminal neuralgia, as well as certain movement disorders like tremors.

The SRS team consists of a neurosurgeon, radiation oncologist, medical physicist, radiation technologist and nursing staff.
