GE Healthcare is highlighting new radiation oncology technologies at this week's American Society for Radiation Oncology (ASTRO) meeting in Atlanta.
Metals in objects such as prostheses, screws, or dental fillings often generate streak-like artifacts on CT scans. GE's smart metal artifact reduction (MAR) uses a projection-based method to reveal anatomic details obscured by such metal artifacts.
Another new technology, GE's deviceless 4D, eliminates the need for an external device when creating motion-compensated 4D CT scans. The technology offers high-quality images and workflow efficiency in 4D motion assessment for thoracic and abdominal tumors affected by respiratory motion, the company said. It is pending U.S. Food and Drug Administration (FDA) 510(k) clearance.
Meanwhile, version 9 of the company's AdvantageSim MD software helps improve productivity with new tools for planning routine and advanced delivery techniques, such as adaptive radiation therapy with CT atlas-based contouring and replanning. AdvantageSim MD 9 also supports planning workflows and access from virtually any networked PC or the CT simulator console.
GE is also showing the 1.5-tesla GEM RT Open Head & Neck Suite shown earlier this year, which is designed specifically for radiation therapy planning with the company's GEM coils.
