Washington, DC, United States, 2013/06/17 - Today at #MDCT2013, GE Healthcare showcased its innovative technologies designed to solve the toughest challenges in CT imaging (NYSE: GE). NYSE: GE
“The toughest CT challenges include cardiac CT for high heart rate patients or patients with highly calcified vessels, improving CT specificity to reduce unnecessary follow-up exams, and obtaining the highest CT image quality at the lowest possible dose,” said Eric Stahre, Vice President and GM, Global CT and PET/CT for GE Healthcare. “Our FREEdom technologies address these challenges in a significant way, and in less than one year after their introduction, we now have more than 200 installations worldwide.”
FREEdom Edition technologies on the Discovery* CT750 HD FREEdom Edition and the Optima* CT660 FREEdom Edition help to solve the toughest challenges in cardiac CT. While gantry speed alone cannot completely freeze coronary motion, especially at high heart rates, SnapShot* Freeze intelligent coronary motion correction is designed to deliver an effective temporal resolution of 29msec. “The FREEdom Edition has taken cardiac scanning to a new level in my facility,” said Dr. James Earls of Fairfax Radiology. "SnapShot Freeze is now completely integrated into my clinical paradigm and is used routinely in patients with both low and high heart rates to deliver diagnostic quality images in virtually every case.”
Gemstone Spectral Imaging (GSI) is moving CT beyond anatomy alone to provide information about tissue composition. GSI is ushering in a new era of CT specificity through capabilities including lesion characterization, metal artifact reduction, kidney stone composition, coronary plaque, and myocardial perfusion.
And new since last year’s MDCT, GSI Cardiac is now being routinely used as the world’s first cardiac spectral CT. According to Dr. James Earls,“with GSI Cardiac, we have enhanced visualization of the coronary lumen in cases of high calcified plaque loads. We do this by viewing the vessels at different monochromatic energies using the GSI Viewer 3D. Previous challenges encountered because of calcium blooming in the coronaries and beam hardening in the myocardium have been reduced and overall image quality improved."
Lower Dose Innovations
Over the past 15 years, GE Healthcare has invested over $800 million to help redefine “low dose” with innovative image reconstruction technologies and novel dose-reporting solutions. GE Healthcare CT scanners are built on the proven platforms of ASiR*^ and Veo*^ image reconstruction technologies. ASiR is installed on more than 3,500 GE CT systems worldwide and has been used for more than 20 million scans. Veo*^ is the world’s first ever model based iterative reconstruction that enables CT imaging under 1 millisievert with profound clarity.
As part of GE’s first-of-its-kind Blueprint initiative, the GE Blueprint benchmark supports healthcare providers’ goals of a comprehensive, programmatic approach to radiation dose management. To date, GE has provided this free Benchmark report to many U.S. health systems and hospitals.

^ In clinical practice, the use of ASiR and Veo may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physician should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
