TomoTherapy out of Madison, Wisconsin is releasing a new radiation oncology device at the Annual Meeting of the American Society for Radiation Oncology (ASTRO) in Chicago next week. The company touts its TomoHD as an all-purpose radiation therapy system that packs lots of useful clinical and operational features:
The TomoHD treatment system combines TomoHelicalSM and TomoDirectSM delivery modes. The TomoHelical technique affords continuous 360-degree delivery for gold-standard treatment quality and targeting of complex volumes. The TomoDirect modality—introduced in 2008—offers a discrete-angle delivery option, with 3D conformal radiation therapy (3DCRT) capabilities, for highly efficient treatment of more routine indications. In both delivery modes, clinicians follow the same basic process for planning, imaging and treating targets of up to 160 cm in length with no need to reposition the patient and no need for field junctioning. In addition to extended delivery versatility, the TomoHD treatment system comes complete with 1, 2.5 and 5 cm primary collimator settings that enable users to select the right beam slice width for each case, depending upon conformity and efficiency needs.
The TomoHD treatment system also includes large touch-screen Positioning Control Panels (PCPs), which allow for high-fidelity positioning adjustments of 0.1 mm in X, Y and Z directions, and a hands-free patient unload feature. The TomoHD system also integrates many infrastructure advances to maximize uptime and operational efficiency.
To aid workflow, the TomoHD system includes 14 blade computing power, which facilitates simultaneous optimization of multiple treatment plans—at twice the speed of the Hi·Art treatment system’s standard configuration.
