FDA Clears Siemens Radiation Therapy Workflow Features

Siemens Healthcare RT Pro Somatom Definition AS Open CT Simulator MARIS
January 29, 2014 — The U.S. Food and Drug Administration (FDA) cleared Siemens Healthcare’s RT Pro edition, a package of features designed to enhance radiation oncology workflow for Siemens’ Somatom Definition AS Open CT simulator. The RT Pro edition of the Somatom Definition AS Open helps deliver high image quality for all needs in radiation oncology, including large patients, patients with metal implants and those who experience tumor motion.
Innovations in the RT Pro edition include MARIS (Metal Artifact Reduction in Image Space), which helps ensure accurate CT data for treatment planning by reducing image-distorting beam-hardening artifacts caused by a patient’s metal implants. Added to Siemens’ respiratory gating solution, the t-minIP and t-MIP features visualize tumor movement in one image to help analyze tumor motion and contouring. Also, Siemens’ HD FoV Pro algorithm uses intelligent contour and attenuation estimation to improve visibility outside the scan field-of-view (sFoV) through the extended 80-cm FoV. MARIS, t-minIP, t-MIP and HD FoV Pro are all standard with the RT Pro edition. The previously available Dual Energy feature is included as an option on the RT Pro edition to help reduce metal artifacts and increase soft tissue contrast.
