TomoTherapy
TomoTherapy® is a form of external beam radiation used to treat a variety of cancers. Through UCHealth, you have access to the advanced TomoTherapy® Hi-Art® system, one of fewer than 150 in the world.
Sophisticated, precise treatment
Advanced technology for precise radiation delivery
As a new way to deliver radiation treatment for cancer, TomoTherapy offers a very sophisticated form of intensity-modulated radiotherapy (IMRT) that combines treatment planning, CT scans for image-guided patient positioning, and radiation treatment into one integrated system.
By directing high doses of radiation to exact locations in shorter periods of time, TomoTherapy helps minimize effects on surrounding healthy tissue and reduces the length of your treatment cycle.
Adaptive technology adjusts to your progress
During your first short pass through the system each day of treatment, your doctors get new 3-D image scans that help identify the precise size, shape, and location of tumors.
Because your body and your tumors constantly change during the period of your radiation therapy, your doctors adapt and make adjustments just before you receive targeted treatment in the second pass through the TomoTherapy system. They customize the size, shape, and intensity of the radiation beam to match changes in your body and changes in the tumors every day. That reduces the exposure of healthy tissue to radiation.
