Radiation oncology firm Accuray has debuted a new TomoTherapy H series of radiation therapy systems at this week's American Society for Radiation Oncology (ASTRO) annual meeting in Boston.
TomoTherapy H series features the TomoHDA system, a fully integrated 3D image-guided radiation therapy system that builds upon the technologies used by TomoTherapy's Hi-Art and TomoHD systems.
Key features include Accuray's new TomoEdge dynamic jaws technology, which provides users with added flexibility in treatment delivery by sharpening dose fall-off and accuracy. When TomoEdge is used to treat patients with head and neck tumors or prostate cancer, beam-on time may be reduced by half, according to the company.
Another key feature of TomoHDA is its VoLo technology, which employs a new dose-calculation algorithm and advanced graphics processing technology designed to increase clinical efficiency, throughput, and flexibility.
Using VoLo, the TomoHDA system allows the creation of highly conformal treatment plans. TomoHDA also includes a fanbeam CT system capable of producing images 50% faster, facilitating improved patient repositioning time and potentially reducing the overall time a patient is on a treatment couch.
Also included in the TomoTherapy H series is the new TomoH system, which streamlines 3D CT daily image guidance and ultrafast multileaf collimator modulation, enabling the delivery of the dose to achieve precise target homogeneity while sparing surrounding healthy tissue.
