Radiosurgery: How It Works

Stereotactic Radiosurgery delivers radiation more accurately than conventional radiation. It creates high-energy beams of radiation strong enough to deactivate even the most aggressive tumors.

Stereotactic Radiosurgery also reduces the risk of damage to healthy areas of the brain. We often recommend it for brain tumors in hard-to-reach places.

Choosing Dr. Rao’s Hospital for Stereotactic Radiosurgery

An alternative to brain surgery, Stereotactic Radiosurgery uses focused radiation to target tumors, vascular malformations and other abnormalities in the brain.

Before, During & After the Procedure

The procedure is simple and painless.

1. Preparation

We attach a mesh covering or frame to prevent your head from moving. This helps us accurately target the treatment.

2. Imaging

We determine the exact size, shape and position of the target in your brain. You’ll have MRI, CT or angiography scans.

3. Treatment Planning

Dr Rao uses your scans to develop a precise treatment plan. No two treatment plans are alike.

4. Treatment

When treatment starts:

• You lie down on the treatment couch.
• The couch moves into the dome section of the unit.
• The team monitors the procedure at all times.

The treatment lasts anywhere from a few minutes to more than an hour, depending on the size and shape of the target.

During the treatment, you can:

• Stay awake
• Talk to the doctor or nurse
• Listen to music

5. After the Treatment: Recovery Time

If you had an angiogram, you might have to lie quietly for several more hours.

You may stay overnight for observation or return home immediately. However, you should be able to return to your normal routine in a day or so.

6. Follow-Up

The effects of your treatment will occur over time – a period of weeks or months. We may evaluate your progress with follow-up scans.
