LOS ANGELES, CA - GE Healthcare has announced a "proton package" on its LightSpeed RT16, containing the options a facility may need to conduct RT simulation and proton therapy planning. The technologies were demonstrated at this week's 49th annual meeting of the American Society for Therapeutic Radiation and Oncology in Los Angeles.

DOTmed talked to GE Healthcare's General Manager of Oncology Paul Anderson, who said that "Proton Therapy has the potential to revolutionize cancer treatment and part of the key to making this therapy practical is precise tumor imaging, which the [LightSpeed] RT16 and [Advantage] 4D with respiratory gating can help achieve."

GE's signature wide bore 16 slice CT scanner provides sub-millimeter imaging to ensure excellent edge detection and image quality, allowing for precision planning and diagnostic confidence. GE's Proton Package provides the tools needed to begin simulation for advanced Proton Therapy, "right out of the box."
The LightSpeed RT16 Proton Package includes:

-AdvantageSim MD
AdvantageSim MD provides complete volume definition and geometric beam placement capability for radiotherapy. It provides enhanced workflow featuring simultaneous multimodality contouring and automated organ segmentation. By fully integrating respiratory motion data it allows the user to review, contour and plan in one simulation session.

-Advantage 4D Respiratory Gating with Varian RPM
Varian's Real-time Position Management (RPM) along with GE's Advantage4D, gives clinicians a powerful weapon against patient motion, one of the largest barriers to successful RT planning. The innovative system is designed for use anywhere respiratory motion is encountered, which could affect regions beyond the lungs to the kidneys, liver and through the pelvis, allowing for more accurate tumor tracking. Using data gathered by the Varian RPM Respiratory Gating System, GE's Advantage4D captures the full range of motion of critical internal structures and lesions, throughout patient respiration. This helps oncologists to visualize the critical organs to plan for a more targeted radiation treatment.

-The proton package also includes a precision laser system, a Diacor Carbon RTP Flat Pad and a GT 2000 Scanning Table.

About the LightSpeed RT16 Wide-Bore CT scanner

As the imaging demands for radiation therapy planning increase (such as the high resolution precision needed in proton therapy), the LightSpeed RT16 is uniquely positioned to provide resolution, power and speed to meet challenging clinical needs. With the high power generator and tube capability, fast gantry speeds, and an extra large bore for better patient positioning, clinicians have freedom to see the patient's entire anatomy in four dimensions with substantial detail.
