Looks like a CT scanner because it is a CT scanner, allowing efficient 3D CT imaging to be used for ensuring the accuracy of treatment for every patient, every day. For more on the history of this technology go here.
Delivers helical (continuous 360º) IMRT that uses tens of thousands of narrow beamlets, all targeting the tumor and individually-optimized to contribute to the total tumor dose
Offers by far the most beamlets of any form of IMRT, which translates to the most precise conformal radiotherapy available (go here). The benefits from Tomotherapy have been demonstrated for multiple cancer sites (go here).
The main advantages can be shown treating a lung cancer patient, the beam can be targeted to avoid normal lung and since the tumor is imaged everyday on CT scan, the doctor can verify that the tumor is getting smaller (see video here).

TomoTherapy® Highly Integrated Adaptive Radiotherapy (HI-ART) is a new radiation therapy option
The TomoTherapy® HI-ART system combines an advanced form of Intensity Modulated Radiation Therapy (IMRT), the accuracy of CT scanning technology and advanced tools for planning and delivering radiation therapy in one machine.
With TomoTherapy® HI-ART, the Radiation Therapy Team can:
Traditional radiation therapies project radiation on a tumor from a few directions. TomoTherapy® HI-ART allows your CTCA Radiation Therapy Team to deliver precise and powerful doses of radiation therapy from 360-degrees.
An on-board CT scanner helps your CTCA care team determine if your tumor has shifted or changed shape since your last treatment. This information allows your radiation oncologist to plan your treatment better to avoid damage to muscle tissue, the spine, the lungs and other sensitive organs.
If you have reached your maximum tolerance dose of traditional radiation, or if your tumor is in a hard-to-reach area, TomoTherapy® HI-ART may open new doors to advanced radiation therapy treatments.
