Spare More Normal Tissue for More Cases
The TomoTherapy® System was designed around patients from the ground up. While the system is well-established in the oncology market, our continued investment in innovation enables us to continually bring new capabilities to market and set the standard for individualized and precise treatment of tumors anywhere in the body.
Designed with the functionality of a CT scanner, the TomoTherapy System uses integrated imaging to enhance treatment accuracy and patented beamlet-based delivery to ensure precision. Together, these features enable treatments to be customized for each patient, minimizing exposure to healthy tissue and measurably mitigating side effects. A unique helical design also enables treatment of a broader range of tumors and expands radiation therapy options for more patients.
TomoTherapy System Benefits
Treatment DeliveryThe design of the TomoTherapy® System reflects the realities of radiation treatment — not only is every patient unique, but the exact location of their tumors and healthy tissue can change significantly from one treatment to the next. The TomoTherapy System achieves precision and efficiency despite these continuous changes by combining CT imaging with a radiation treatment delivery system. This unique design enables use of highly efficient daily 3CT imaging to perfectly position patients before each treatment delivery. The system’s unique ring geometry design enables state-of-the-art radiation treatments, including intensity-modulated radiation therapy (IMRT) and 3D conformal radiation therapy (3DCRT).
TomoHelicalTomoHelical™ Treatment Delivery, the TomoTherapy® System’s flagship helical mode of treatment, combines 360 degree fan-beam delivery of intensity-modulated radiation therapy (IMRT) and megavoltage CT (MVCT) imaging for gold-standard treatment and targeting of complex tumors. During treatment delivery, the linear accelerator completes multiple 360-degree rotations around the patient, while the couch passes through the center bore of the system. Continuous high-dose rate delivery enables for shorter beam-on times than most other radiation treatment systems.
TomoDirectThe TomoTherapy® System’s TomoDirectTM modality offers a discrete-angle, non-rotational delivery option, with 3D conformal radiation therapy (3DCRT) capabilities, for highly efficient treatment of routine indications. It enables creation of treatment plans that include between 2 and 12 target-specific gantry angles, as well as user-defined levels of modulation for the plan, including a 3D delivery mode.
Data ManagementThe TomoTherapy® Data Management System provides comprehensive storage and processing of patient data generated over the life of the TomoTherapy planning and treatment workflow.
- Import and store imaging studies
- Store completed treatment plans; make them available for review and approval
- Store a record of each day’s treatment procedures
- Manage the flow of patient data throughout the system from a single location
- Ensure the security of patient data with scheduled database backups and the use of multiple disk drives
- Schedule treatments in a central calendar (held and managed in the OIS)
- Systematically capture treatment procedures in the OIS
- Facilitate charge capture and billing for treatments
- Incorporate treatments in the Electronic Medical Record (EMR)
Treatment PlanningThe TomoTherapy® Treatment Planning System enables users to quickly and intuitively create sophisticated IMRT or 3DCRT treatment plans for accurate treatment of simple and complex cases. The system is based on diagnostic CT and anatomical structure data that include specified dosimetric goals and constraints. Three-dimensional dose distributions and dose-volume histograms (DVHs) are available as analytical tools to either accept or modify—and re-optimize—the planned dose.
- Remote Software Solutions — for anywhere-anytime access by authorized users through a secure Citrix-based website
- Planned Adaptive™ software — the first commercially available solution that enables clinicians to account and adjust for day-to-day patient changes
- VoLO™ Technology plan calculator — leverages high-end graphics processing unit (GPU) hardware and software capabilities to perform dose calculations and optimizations for multiple large plans in minutes
To assess patient setup corrections based on daily megavoltage CT (MVCT) imaging for four anatomic treatment sites treated on tomotherapy.
The authors evaluated the procedure on multiple image datasets from prostate cancer patients and gynecological cancer patients. Compared to rigid alignment, the proposed method improves volume matching by over 60% for the critical organs and reduces the prostate landmark registration errors by 50%.
To evaluate dosimetry of helicoidal tomotherapy versus three-dimensional conformal radiotherapy (3D-CRT) with and without IMRT for the treatment of soft tissue sarcoma (STS) of the thigh.
Helical tomotherapy is a technique for delivering intensity modulated radiation therapy treatments using a continuously rotating linac. In this approach, fan beams exiting the linac are dynamically modulated in synchrony with the motion of the gantry and couch. Helical IMRT deliveries have been applied to treating surface lesions, and the purpose of this study was to evaluate the accuracy of dose calculated by the TomoTherapy HiArt treatment planning system for superficial planning target volumes (PTVs).
This manuscript describes a direct comparison between radiation treatment plans in terms of dosimetric outcomes created by two different IMRT systems: TomoTherapy HiArt and dynamic linac intensity-modulated radiotherapy (dIMRT).
Radiation treatment of scalp malignancies can be a challenge due to the multiple curved surfaces to which homogenous dose must be delivered. The most readily available techniques utilize linear accelerator-based technique of opposed lateral electron field abutting opposed lateral photon field with central blocking.
System OptionsThe TomoTherapy® H™ Series offers interactive planning and efficient delivery of highly sculpted doses for personalized and consistent treatments. Integrated daily CT image guidance enables precise patient positioning, margin reduction, adaptive planning and pinpoint dose accuracy for every radiation therapy patient.
