GE Showcases VCT for Cardiac Imaging

June 14, 2007 - GE Healthcare recently demonstrated technology advances in Helical Shuttle imaging, using the company’s LightSpeed VCT by generating CT Scans with an expanded image coverage of 210 millimeters on a 40-millimeter detector for both cardiac and liver exams.

Helical shuttle scanning continues to hold promise by providing wider image coverage for both dynamic angiography and perfusion studies. 210millimeters of coverage enables whole organ anatomical and physiological assessment on existing Computed Tomography (CT) technology.

"The underlying technical concept behind Helical Shuttle was to break through the old paradigm that helical scans must be performed at a constant table speed or pitch, relative to the slice thickness," said Brian Duchinsky, General Manager of Global CT at GE Healthcare. "This breakthrough is enabled by an innovative, real-time scan control architecture. Additionally, our engineers have been developing improved reconstruction algorithms that work to produce images acquired with “Helical Shuttle” without artifacts previously associated with varying table speed. These powerful combinations of technology enhancements have the potential to unlock a host of exciting new advanced clinical applications."

The research was performed at Osaka and Kinki Universities, Japan, by Professor Takamichi Murakami, Chairman, Department of Radiology at Kinki University Hospital.
