Dr Bernard Eden: TomoTherapy is one of the most advanced radiation therapy delivery systems available today. It treats the cancer in a similar way that a CAT scan takes a picture of a cancer. So basically what we’re doing is we’re treating slices of the cancer and we’re designing the radiation to be sculpted around that cancer in each slice, and we just spiral through the tumor in order to deliver the radiation around the geometry of the tumor.
What this allows us to do is to very finely, and very precisely, deposit the energy along the edges of the tumor and within the tumor while minimizing and at times eliminating the radiation to the surrounding normal tissues. This has tremendous benefits for the patient because it allows us to increase the dose of radiation to the tumor. Thereby, hopefully providing better tumor control, and decreasing the dose and as I mentioned eliminating at times the dose to the normal tissues thereby having less side effects and damage to the normal tissues.
TomoTherapy® HI-ART, a form of radiation therapy, precisely targets tumors while reducing radiation exposure to surrounding normal tissue. Listen to Dr. Bernard Eden discuss the benefits of this advanced technology.
