Stereotactic radiosurgery is a nonsurgical form of radiation therapy that is used to eliminate or shrink tissue in the brain, head and neck in a single treatment. It is used both for benign (noncancerous) conditions as well as cancer.
Stereotactic body radiotherapy, or SBRT, is used to deliver 1-5 targeted, high-dose treatments to a location within the body.
Stereotactic Radiosurgery Benefits
Stereotactic radiosurgery using Gamma Knife Icon offers the following benefits over whole brain radiation:
- Targeted to just the area needing treatment
- Fewer unpleasant side effects, such as hair loss, nausea, fatigue and memory deficits
- Allows for a higher-dose, single treatment
Stereotactic Radiosurgery at Valley
Gamma Knife radiosurgery is a very effective method for treating cancer and neurological conditions in the brain, head and neck.
How stereotactic radiosurgery works:
- Highly focused beams of radiation are directed to the treatment area.
- The shape and dose of the radiation are optimized to hit only the target, without damaging surrounding healthy tissue.
- The procedure is simple and virtually painless.
- Patients are treated in one session and can resume normal activity soon after treatment.
Stereotactic Body Radiotherapy Benefits
Stereotactic body radiotherapy, or SBRT, using TrueBeam offers the following benefits:
- Ensures accurate targeting of tumors via CT scans taken before each treatment
- Uses respiratory gating, which tracks a tumor’s motion while the patient breathes and syncs radiation delivery with breathing
- Shorter treatment times than other external beam radiation linear accelerators
SBRT at Valley
Real-time imaging tools allow clinicians to “visualize” the tumor they are targeting, allowing them to consistently treat these tumors with accuracy measured in millimeters.
How SBRT works:
- By administering higher doses of radiation with more precision, this accelerator delivers treatments up to 400 percent faster than other accelerators.
- Most treatments will take just a few minutes a day, whereas treatments with other types of linear accelerators can take 30-60 minutes.
- Using gating and fiducial tracking, treatments are given only when the patients’ tumors are in specific locations during the respiratory cycle.
Why Choose Valley for Stereotactic Radiosurgery or Stereotactic Body Radiotherapy?
- Gamma Knife technology and experience: Valley was the first hospital in northern New Jersey to offer Gamma Knife Icon stereotactic radiosurgery.
- Improving patient outcomes: Stereotactic body radiotherapy (SBRT) allows for very precise, focused treatments that can improve patient outcomes.
- Real-time imaging for precision: Real-time imaging accounts for patient movement that can affect the ability to target the tumor accurately. Even small movements, such as when you breathe, can move a tumor slightly out of place and jeopardize the ability to target the tumor with precision. Real-time imaging tools allow the system to program itself during a patient’s breathing cycle to identify and adjust for these slight movements.
- Patient safety: The TrueBeam system has many patient safety features in addition to precision, including enhanced communication technology that allows for constant interaction between the patient and the therapist during treatment. Three closed-circuit television systems also enable the therapist to monitor the patient at all times. In addition to greater safety, communication during treatment can alleviate stress for patients.
