Stereotactic Radiotherapy

Highly Precise External Radiation for Tumors in the Brain, Spinal Cord, Lung, Liver and Pancreas
Novalis Tx Radiosurgery Platform

The Novalis Tx Radiosurgery Platform Shapes Cancer Care Around You

Scott & White is one of the only institutions in Texas to offer the Novalis Tx Radiosurgery Platform, the most advanced stereotactic radiosurgery machine available.

The Novalis Tx is a noninvasive, shaped-beam cancer treatment that reduces your treatment time to just minutes.

“Radiosurgery does exactly what surgery does — except that it’s not done by cutting with a knife. It’s done with very focused beams of radiation under image guidance such that small tumors can be killed without damaging any surrounding normal tissue.”

Nitika Thawani, MD, Radiation Oncology; Director of the Stereotactic Radiation Program

Scott & White offers stereotactic radiotherapy, a highly precise form of radiation that delivers much higher doses than traditional radiation while sparing surrounding healthy tissue.

Stereotactic radiotherapy requires a team approach, performed in combination by radiation oncologists and other specialists. Your radiosurgery team will consist of:

  • Your radiation oncologist
  • Your interventional radiologist
  • Your medical radiation physicist
  • Radiation therapists
  • Simulation technologists

Benefits of Stereotactic Radiotherapy

  • A highly advanced and exact form of radiation therapy
  • Utilizes computer robotic delivery to ensure accuracy
  • Conforms precisely to the 3-D shape of your tumor, minimizing damage to surrounding healthy tissue
  • Uses the industry’s highest dose rate to stop tumor growth, and in some cases, shrink or destroy your tumor
  • Can reach small tumors that once were considered inoperable
  • May be performed frameless for your comfort
  • May be used for initial radiation and for re-radiation at the same site
  • Requires special sequence of MRI imaging prior to treatment

Stereotactic radiotherapy is based on these components:

  • 3-D imaging using a web of MRI and CT scans to map exactly where your tumor is
  • Precise immobilization of your body so that the X-ray beams strike only your tumor, avoiding surrounding healthy tissue
  • Rapid and exact targeting of the tumor so that your tumor is killed quickly

Types of Stereotactic Radiotherapy

Scott & White offers two forms of stereotactic radiotherapy:

Scott & White uses Image-Guided Radiation Therapy (IGRT) and other sophisticated techniques to help maximize the accuracy of your treatment. Find out more »

  • Stereotactic radiosurgery
  • Fractionated stereotactic radiotherapy

Your physician team will discuss which option is best for you.

Stereotactic Radiosurgery

  • Administered in a single dose (a one-time treatment, not a surgical procedure)
  • Precisely targeted to tumor
  • Highly concentrated X-ray beam

Sometimes called gamma knife or cyberknife, stereotactic radiosurgery is a radiation treatment, not a surgical procedure.

Fractionated Stereotactic Radiotherapy

  • X-ray dose divided into three to five fractions (treatment sessions)
  • Precisely targeted to tumor
  • Highly concentrated X-ray beam

Risks and Side Effects of Stereotactic Radiotherapy

When discussing radiation treatment options with you, your physician will discuss possible risks and side effects with you. Each radiation therapy approach is different and each person’s reaction can vary.

At Scott & White, your radiation oncologist will see you through treatment and help you manage any side effects.
