TomoTherapy®

What is TomoTherapy®?

TomoTherapy® combines a form of intensity modulated radiation therapy (IMRT), with the accuracy of computed tomography (CT) scanning technology, in one machine.

With this technology, we can deliver precise radiation to match complex tumor shapes while avoiding sensitive structures. Using built-in CT scanning to confirm the shape and position of the tumor before each treatment, TomoTherapy may reduce radiation exposure to healthy tissues and organs.

Before every treatment, scanning technology provides a 3D image of the treatment area, so the radiation beams can be targeted according to the size, shape and location of the tumor(s) on that specific day. The “slice therapy” approach treats tumors one layer at a time. Side effects are often reduced  because less radiation reaches healthy tissues and organs.

Many cancer patients who have reached their maximum tolerance dose of traditional radiation may be a candidate for TomoTherapy radiation.
