Novalis Surgery

Q: What types of conditions can be treated with Novalis Tx Radiosurgery?

A: Novalis Tx Radiosurgery can treat non-cancerous and cancerous conditions of the entire body such as:

  • Arteriovenous malformations (AVM)
  • Cavernous angiomas
  • Trigeminal neuralgia
  • Intractable seizures
  • Parkinson’s disease
  • Brain metastases/Gliomas
  • Acoustic neuromas
  • Recurrent brain tumors
  • Pituitary adenomas
  • Meningiomas of the skull base
  • Craniopharyngiomas
  • Spine Tumors/Metastases
  • Prostate Cancer/Metastases
  • Liver Tumors/Metastases
  • Lung Tumors/Metastases

Q: How does Novalis Tx Radiosurgery work?

A:
Novalis Tx Radiosurgery incorporates a powerful linear accelerator, which rotates around the patient to deliver treatment beams anywhere in the body from virtually any angle. A set of sophisticated image-guidance and motion management tools provide clinicians with detailed information about the shape, size and position of the targeted lesion, guide patient setup and positioning, and monitor motion during treatment.

Q: Why is fast treatment important?

A:
Prolonged treatment times can affect patient comfort and treatment accuracy. Faster treatments reduce the likelihood of patient or tumor movements, which can impact overall accuracy. In addition to offering one of the industry’s fastest treatment times, Novalis Tx Radiosurgery continuously tracks patient and tumor motion and automatically adjusts the beam of radiation to maintain the highest possible level of treatment accuracy.

Q: What is the treatment advantage of Novalis Tx Radiosurgery over other radiosurgery devices?

A:
Other radiosurgery devices utilize circular beams to treat. As most lesions are irregular in shape, a circular dose does not completely cover the exact shape of the tumor. Novalis Tx Radiosurgery shapes the radiation beam to contour to the exact shape of your tumor or lesion, ensuring the optimal treatment dose is delivered while protecting healthy tissue. The targeted beam adapts to your breathing and other body movements to continuously maintain safe, complete and accurate dosage.

Q: Will there be any side effects?

A:
Novalis Tx Radiosurgery treatment is not painful in most cases and does not require anesthesia. There is no scarring or disfigurement and little risk of infection, compared to conventional surgery. Your doctor will discuss potential side effects with you depending on your overall treatment plan. You may experience a headache, dizziness and fatigue immediately following treatment, so driving is not recommended. Make sure to arrange for transportation home.

Q: What effect can radiation have on my tumor or lesion?

A:
Radiosurgery and radiotherapy use high-energy radiation beams to deliver the prescribed radiation dose directly to tumor cells, causing them to die. Treatment results visible on follow-up scan, may include shrinkage of the tumor or no further tumor growth. Because cell destruction and absorption of the cells within your system can be a lengthy process, it can take up to six months before the effect of treatment can be determined by your doctor.

Q: What is the difference between stereotactic radiosurgery and fractionated stereotactic radiotherapy?

A:
Stereotactic radiosurgery and fractionated stereotactic radiotherapy refer to two radiation treatment delivery methods. Stereotactic radiosurgery delivers a high dose of radiation treatment to the tumor in a single session. Fractionated stereotactic radiotherapy delivers a series of radiation treatments to the tumor over a period of time. While both methods typically involve a similar total dose of radiation, fractionated stereotactic radiotherapy delivers radiation in smaller amounts. Novalis Tx Radiosurgery offers both stereotactic radiosurgery and fractionated stereotactic radiotherapy treatments. Your doctor will recommend the best treatment method for you based on your individual case.

Terms to Know

Radiotherapy – The use of high-energy radiation from X-rays, gamma rays, neutrons and other sources to treat tumors and destroy cancer cells.

Radiosurgery
– A radiation therapy procedure that delivers a large dose of radiation to a tumor over one to five treatment sessions.

Stereotactic Radiosurgery
– Radiation treatment of a tumor that is applied in a single session with a high dose of radiation.

Fractionated Stereotactic Radiotherapy
– A series of radiation treatments over a period of time.
Image-Guided Radiosurgery (IGRS) – Radiation treatment that uses real-time X-ray and CT imaging to deliver precisely focused, high-energy radiation to a tumor.
