At this year’s American College of Cardiology (ACC) meeting recently held in Chicago, GE Healthcare debuted a cardiac CT machine that provides intelligent motion correction. The Discovery CT750 HD FREEdom Edition system, which is awaiting 510(k) clearance from the FDA, also offers enhanced coronary visualization and improved plaque assessment and perfusion calculation.
The technology makes use of a functionality that GE terms “SnapShot Freeze” to reduce coronary motion, enabling the unit to determine vessel position and intelligently correct the effects of motion during cardiac CT exams.
“FREEdom Edition has the potential to change the way we think about cardiac CT, both for the patient and the clinician,” explained Jonathon Leipsic, MD, head of radiology at Providence Health, St. Paul’s Hospital in Vancouver in a statement. “By intelligently reducing motion artifact in CT images, SnapShot Freeze improves visualization, which is important for coronary artery interpretability.”
According to GE, the spatial resolution that the system offers is up to 66% greater than comparable systems, which facilitates the detection of stenosis in coronary vessels.
The system supports low-dose cardiac imaging, delivering radiation doses of less than 1 mSv.
