Overview

Radiation has been used as a form of treatment for tumors since almost 100 years. But with advances in technology there is now a focus on treating the tumour aggressively while saving all surrounding normal structures. This is possible when there is maximum radiation delivered to the tumour and minimal radiation to the surrounding tissues.

What is Stereotactic Radio Surgery (SRS)?

Stereotactic RadioSurgery is a non invasive, image guided; precise surgery.3D images of the tumour are taken before and during the procedure. High density precisely directed radiation beams are then guided to the tumour while sparing the adjacent tissues. This ensures better tumour control, better survival rates and lesser side effects.

Novalis TX

Varian Medical Systems (USA) and BrainLAB (Germany) have developed the NovalisTx which is today the most versatile and powerful RadioSurgery system.

What are the advantages of SRS?

  • Non-invasive
  • Image guided : continuous 3D imaging of the tumour during surgery
  • Frameless : no immobilization using a head ring which attaches to the skull
  • Faster treatment : radiation is delivered in minutes and does not take hours like conventional systems.
  • Even irregularly shaped lesions can get uniform radiation in a single session.
  • Extra cranial tumours can also be treated.
  • The radiation beams can adapt to breathing and other body movements to continuously maintain safe, complete and accurate dosage.

What are the advantages of SRSwith NovalisTX?

  • High Speed, High Density, Deep Penetrating Treatment which attacks only the tumour and keeps adjacent organs and tissues safe.

Minutes Are Faster Than Hours

  • Offering a dose rate of 1000MU per minute, NovalisTx is the most powerful RadioSurgery system available offering fast treatment-often in minutes.

Visualising The Back And The Front

  • NovalisTx covers the anterior, lateral and even posterior approaches to deliver treatment.

Integrated Data Access

  • Eclipse treatment planning support software provides a powerful treatment planning platform which integrates, collates and stores patient data. This ensures that images are used to accurately localize tumours and critical organs.
  • ARIA combines all patient records i.e. images, administrative, clinical and financial data into one single file in order to help link medical, radiation and surgical oncology processes.
  • All patient data has restricted access, so only the treatment team can access this data.

A Healthy Dose

  • A very precise, high intensity shaped beam of radiation attacks the lesion while clearly sparing adjacent critical areas.

Beams Which Adapt To Moving Targets

  • Tumours move when patients breathe and move during treatment.
  • The NovalisTx captures real time continuous images of the lesion and the radiation beam is shaped to attack only the lesion and spare all adjacent organs and tissues (Image Guided Radiation Therapy).

3D Definition Of Target

  • NovalisTx combines 2D imaging with built-in volumetric cone beam CT scanning to define the lesion with 3D precision.

Continuous Image Monitoring

  • The NovalisTx has an On Board Imager and ExacTrac X-Ray 6D to enable fast highly accurate image guidance and automatic positioning of the patient for initial setup and regular verification during treatment.

Deeper Penetration Deeper Conformality

  • The NovalisTx multiple energy system (6MV to 20 MV) produces more energy and penetrates deeper so that deep-seated tumors can be treated while keeping all adjacent organs and tissues safe..

Wide Range Of Treatment Options

  • The NovalisTx offers a versatile spectrum of treatment options for cranial and extra-cranial indications like spine, lung, liver and prostate lesions.
  • Benign and malignant lesions, Brain metastases, Arteriovenous malformations and Functional lesions can be treated easily.
  • Acoustic neuromas, Meningiomas, Pituitary adenomas, Recurrent brain tumours, and Cavernous angiomas come within treatable range.
  • Intractable seizures and Parkinson’s disease can also benefit from this form of treatment.
