Latest Generation Radiosurgery

The TomoTherapy Hi-Art2® system is the third generation of the radiosurgery technology, which began with the Gamma Knife® in 1968 and was continued with the CyberKnife® in 1994.

On June 1, 2003 Thompson Cancer Survival Center became the first clinical facility in the world with TomoTherapy.

The system's exact tumor mapping; image-registration patient positioning system; and helical-pattern, intensity-modulated, collimator-controlled radiation beam allow maximum doses to be focused on the area to be treated with minimum damage to surrounding tissue.

The TomoTherapy Hi-Art2® system can treat areas anywhere in the body, of any size from less than half an inch up to five feet long with accuracy of better than +/- 1/50th of an inch and power never before possible.

Vertebral Metastasis

TomoTherapy's combined image-and-treat technology and 360° spiral treatment pattern provide unprecedented accuracy. Patients who have already received a maximum dose of conventional radiosurgery can still be treated with TomoTherapy.

Brain Tumors

With TomoTherapy's on-board CT scanner, patients are positioned and treatment areas are defined immediately before each dose, so nothing needs to be bolted onto patients heads or implanted in their bodies.

The precision of targeting - and TomoTherapy's unique spiral delivery pattern - allow higher dosages with minimal damage to surrounding healthy tissue.
