TomoTherapy Treatment

The TomoTherapy Hi-Art system is one of the most advanced and versatile radiation therapy systems currently available for the treatment of a wide variety of cancers, and you will not find it anywhere else in Macon County.

TomoTherapy is so precise, it opens the door to treat certain types of cancer that previous radiation methods could not.

The Hi-Art treatment system works by delivering intensity-modulated radiation therapy (IMRT) with a helical (spiral) delivery pattern. Photon radiation is produced by a linear accelerator (or linac for short), which travels in multiple circles around you and moves in unison with a device called a multi-leaf collimator, or MLC. Meanwhile, the couch is also moving, guiding you slowly through the center of the ring. Each time the linac makes a loop around you, it directs a unique, optimized set of radiation beamlets at your tumor. Quite literally, the Tomo process runs rings around your cancer!
