New PET/CT Offers High Sensitivity, 'Motion Free' Technology

GE Healthcare is extending its Discovery product line with the introduction of the new Discovery PET/CT 600.

This system delivers the next evolution in PET/CT technologies, bringing powerful options to physicians to discover ways to detect disease early and manage with confidence. This new platform offers the scintillator with the high sensitivity, the next generation of MotionFree technology to capture detail and precision in areas subject to motion, plus enhanced workflow and fast reconstruction with the IBM BladeCenter.

This new addition to GE’s Discovery family of scanners continues GE’s commitment to help enable the earlier detection and monitoring of disease with advanced molecular imaging technology, in both hardware and software.

The new system will be optimized for use in oncology, which represents more than 90 percent of clinical PET/CT exams. The system continues using high-sensitivity crystals in the industry, along with GE’s exclusive VUE Point HD, High Definition imaging to help clinicians advance towards the goal of Motion Free PET/CT imaging. It reportedly has wide-view imaging for PET and CT and according to the manufacturer, has two to four times faster reconstruction.

Discovery Dimension's high-definition PET image processing for patient motion management and clinical productivity provide features that together address motion, which is one of the most significant factors in lesion characterization that degrade today’s PET/CT image quality. These technologies are continuously developed through the work of GE research and global clinical research partners in pursuit of motion free PET/CT imaging. The newest version of Discovery Dimension helps clinicians advance towards the goal of motion free PET/CT imaging by allowing the clinician to address imaging mismatches related to respiratory and cardiac motion. These include motion correction techniques that effectively improve clinical results and minimize blur caused by motion.

GE Healthcare is aslo showing a new application for PET image generation. This technology, called VUE Point, can help improve small lesion detectability, clinical confidence and exam productivity. Available on the Discovery Dimension with new installations or by ContinuumTM field upgrades for installed base Discovery ST systems, clinicians can perform advanced PET image generation to improve both qualitative and quantitative accuracy.

VUE Point incorporates advanced proprietary image reconstruction algorithms; including volume scatter correction and a patented image projection technique developed at GE’s Global Research facility, and is enabled by the Volume CT reconstruction technology development. VUE Point is applicable to both 2D and 3D PET acquisition modes, static, dynamic and motion imaging.
