Services - Treatment

The focus of our business in this venue will be primarily based in non-invasive, stereotactic radiosurgery and radiotherapy. The modalities listed below reflect multifaceted and proven treatment in the areas of cancer and other functional diseases. The technologies can be used for everything intracranially (within the brain) as well as extracranially (anywhere else in the body). This gives the practitioner the diversity to treat all tumors, lesions and anatomical maladies successfully.

Radiation is one of the three most accepted forms of treatment in these areas. The others are surgery and chemotherapy. Any of these three can be used singularly or in synergy with the others. Some of these technologies are offered in many settings such as linear accelerators, whereas others are offered in very few settings such as Gamma Knife and Cyberknife.

Demographics and physician preference play the largest role in deciding what to offer the community. Our objective is to identify and partner with the innovators and early adaptors in this market segment. Our experience and research tell us that the more successful businesses are in for-profit, community based facilities, where there is proactive physician and institutional participation.

Gamma Knife
IMRT (Intensity Modulated Radiation Therapy)

Gamma Knife

Gamma Knife surgery is recognized worldwide as the preferred treatment for brain tumors both benign and malignant as well as for functional diseases of the brain such as arteriovenous malformations, trigeminal neuralgia, tremors and Parkinson's disease. The Gamma Knife allows noninvasive cerebral surgery to be performed with accuracy and precision sparing healthy tissue adjacent to the treated site. It is painless, bloodless and requires usually no overnight stay. This method of radiosurgery is the most dramatic advance in brain surgery in decades and has helped to change the landscape of neurosurgery. There are some variations and other modalities of similar treatment, yet Gamma Knife is recognized as the "gold standard".

IMRT (Intensity Modulated Radiation Therapy)

This is another one of the more technically advanced methods available in external beam radiation therapy. Rather than having a single, large beam of radiation pass through the body, IMRT is broken up into thousands of pencil radiation beams. It allows the user to treat tumors to a higher dose, retreat already irradiated cancers and safely treat tumors located close to vital organ areas. It can translate into a higher cancer control rate with fewer side effects. This is a relatively new market segment with high potential.


Tomotherapy is a fully integrated state-of-the-art radiation therapy delivery system. This product is a compact, cost-effective and high precision therapy system. The design includes a primary beam-shield, reducing costs associated with room shielding which many of the other treatment products require. It also includes an on-board oncology CT system, a fast inverse planning system and excels at treating complex cases (IMRT) as well as cases currently treated more conventionally with 3D or 2D planning. It is designed to target conformal radiation treatment to the patient's tumor while helping to limit damage to surrounding tissues. There has been a vast amount of success in the treatment of many types of cancer including breast and prostate as well as others.
