TomoTherapy gives clinicians everything they need to deliver the best radiation therapy possible.
For more than 80 years, radiation therapy has been used in cancer care. The primary challenges have remained the same:
360º delivery. Conventional machine design allows radiation to be delivered from only a few directions. The TomoTherapy treatment system’s linear accelerator (linac) is mounted to a CT scanner-like ring gantry, which means TomoTherapy treatments can be delivered continuously, from all angles around the patient. More beam directions give physicians more control in how they plan treatments—and more assurance that dose will be confined to the tumor, reducing the risk of short- and long-term side effects.
Thousands of targeted beamlets. The TomoTherapy treatment system uses a patented multi-leaf collimator (MLC) that divides the radiation beam into beamlets, all aimed at the tumor. Typically, tens of thousands of beamlets are used in a single TomoTherapy treatment session. Powerful software optimizes the contribution of each one to the total tumor dose, minimizing exposure to healthy tissue.
CTrue™ image guidance for every patient, every day™. Our unique ring gantry design facilitates a 360º delivery pattern. Perhaps even more importantly, it integrates true CT imaging that can be used on a daily basis to guide the accurate delivery of each treatment session. No other radiation therapy machine offers this seamless integration of image-guided and intensity-modulated radiation therapy. No other machine can.
