TomoTherapy Incorporated is Reshaping Radiation Therapy™ with the TomoTherapy® Hi·Art® treatment system. By integrating CT imaging and helical intensity-modulated radiation therapy, our approach improves the effectiveness and efficiency of radiation treatment for the full range of cancer tumors.

 

 Tomotherapy Incorporated founded on the premise that the best way to harness the power and precision of intensity-modulated radiation therapy (IMRT) is with integrated imaging technology that can guarantee accuracy at every treatment fraction.

Revolutionary Design

Conventional radiation treatment devices are at the end of an evolutionary path that began more than a century ago. The TomoTherapy® Hi·Art® treatment system, in contrast, was designed in the 1990s. Our goal was to develop a machine that could turn advanced, optimized radiation treatment concepts into reality.

The Hi·Art treatment system:

  •       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™

  •       Leverages the ring gantry geometry used in CT scanning for the delivery of state-of-the-art, intensity-modulated radiation therapy (IMRT) from all angles around the patient

  •       Was designed so that highly-precise treatment plans could result in more effective treatment deliveries, with minimized side effects for patients

Complete Integration

All an all-in-one solution, the Hi-Art system facilitates the first fully integrated treatment process for radiation therapy. This greatly reduces the number of technical decisions that need to be made, giving clinicians more time to focus on their patients.

        The Hi·Art treatment system:   

  •       Incorporates easy-to-use software for treatment planning, quality assurance, patient set-up  and treatment delivery, all using the same secure centralized database

  •       Includes a powerful, 32-processor computer system that rapidly creates sophisticated IMRT plans

  •       Stores all patient and plan information in a single location; removing the risk of data transfer errors

Unparalleled precision

The Hi·Art treatment system:

  •         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

 The accuracy

The Hi·Art treatment system’s integrated CTrue™ technology lets clinicians efficiently acquire CT images for every patient, every day. These can be used for positioning purposes, and allow for the quantitative, dosimetric analysis and modification of a patient’s treatment at any point during the treatment course.

 The Hi·Art treatment system:

  •         Ensures accurate delivery of precise helical IMRT plans via 3D image-guided set-up, based on daily pre-treatment CT scans

  •         Increases clinical confidence because it integrates imaging into the treatment geometry; images are fundamentally in the same frame-of-reference as the treatment beams

 

Full Assurance

The Hi·Art treatment system:

  • Allows the same 3D images used in daily patient positioning to be used for dose guidance; this gives clinicians the ability to visualize the dose that will actually be delivered to the patient that day.
  • Makes true Adaptive Radiation  Therapy (ART) practical, with highly integrated Planned Adaptive™ software for evaluating dose and applying any needed changes to the plan

 



 

The Tomo® Process

The TomoTherapy® Hi·Art® system introduces a new, integrated way to deliver radiation treatments for cancer. The process makes it easier on clinicians and patients alike.

Planning. Before beginning a TomoTherapy treatment, the doctor uses 3D images from a combination of scanning technologies (such as CT and MRI) and special software to establish the precise contours for each treatment volume (tumor) and any regions at risk (sensitive organs or structures). The doctor then decides how much radiation the tumor should receive, as well as acceptable levels for surrounding structures. The Hi·Art treatment system calculates the appropriate pattern, position and intensity of the radiation beam to be delivered, to match the doctor’s prescription as closely as possible.

 

 

Patient positioning. As both a treatment delivery machine and a CT scanner, the Hi·Art system allows doctors to take a CT scan just before each treatment. With the scan, they can verify the position of the tumor and, if necessary, adjust the patient’s position to help make sure radiation is directed right where it should be.




 

 

 

 

 

 

Continuous 360º treatment delivery. The Hi·Art treatment system delivers 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 the patient and moves in unison with a device called a multi-leaf collimator, or MLC. Meanwhile, the couch is also moving—guiding the patient slowly through the center of the ring. Each time the linac makes a loop around the patient it directs a unique, optimized set of radiation beamlets at the tumor. Quite literally, the Tomo process runs rings around cancer!
