Stereotactic Radiosurgery

Stereotactic Radiosurgery

For patients diagnosed with a brain tumor, St. Mary Medical Center is among the first in the region to offer Frameless Stereotactic Radiosurgery (SRS) as a breakthrough treatment to fight cancer. Frameless Stereotactic Radiosurgery is a one-time application of a large-dose radiation precisely targeting a tumor.

Traditional methods for delivering SRS required an invasive frame that was screwed into the patient’s skull bone. Today, new technology known as Image-Guided Radiation Therapy (IGRT) has been introduced to allow for the more comfortable frameless SRS. A GPS-type tracking system uses high-resolution X-rays to pinpoint tumors, automatically correcting any inaccuracies in positioning.

St. Mary Regional Cancer Center is among the first cancer treatment facilities in the Delaware Valley area to utilize this frameless technology. Dr. Robert Cardinale, Medical Director of Radiation Oncology at St. Mary, comments, “Because nothing is affixed to the patient’s head, the patient feels no discomfort and can return to normal life activities almost immediately following the procedure. This new technology expands our comprehensive range of services and demonstrates the St. Mary commitment to having the most advanced treatments available to our patients.”

Frameless SRS is considered the next generation of treatment in cancer care. SRS has applications beyond the brain, and radiation oncologists at St. Mary are treating a wide range of tumor sites including prostate, lung, liver, and spine. The St. Mary team is dedicated to offering advanced technology along with clinical expertise to treat even the most complex cases


SRS allows a highly qualified team of cancer specialists to treat a tumor without anesthesia, accompanied by no pain or bleeding, while requiring minimal recovery time. The goal of SRS is to destroy the target tumor without open surgery and without harming nearby healthy tissue. SRS uses focused high-energy radiation beams to destroy tumors by damaging the tumor cells.
