Summary: The 510(k)-pending Revolution CT captured a motion free image of the human heart in just one beat.
December 9, 2013 - One of the most challenging anatomical objects to image is the human heart. More than 60% of patients referred to cardiac CT today were found to have heart rates higher than 60 beats per minute, and some are turned away from being scanned, according to studies from the British Journal of Radiology.
To address this issue, GE Healthcare introduced the Revolution CT scanner at the Radiological Society of North America’s (RSNA) 99th Scientific Assembly and Annual Meeting in Chicago. The 510(k)-pending Revolution CT captured a motion free image of the human heart in just one beat. The system is designed to enable clinicians to clearly see specific areas of the heart that were previously compromised either by a patient’s movement, high heart rate, or a child’s inability to hold his or her breath.
- Revolution CT makes offers spatial resolution, temporal resolution, coverage, and low dose all-in-one. The scanner is 510(k) pending.
Revolution CT makes offers spatial resolution, temporal resolution, coverage, and low dose all-in-one. This convergence enables the following advanced clinical exams:
- Comprehensive cardiac exams with anatomic and functional information in just one heartbeat, even with challenging patients and higher heart rates;
- Rapid, whole-brain stroke assessment at low dose;
- Dynamic liver, kidney, or pancreas oncology workup personalized with perfusion and vascular flow analysis.
The Revolution CT is engineered with technology advances including the 16-cm Gemstone Clarity detector for whole organ coverage, best-in-class spatial resolution at 230 microns for visualizing small anatomy, and a 0.28-second gantry designed and tested for up to 0.2-sec rotation speed. Combined with SnapShot Freeze motion correction technology, the system delivers 24-msec effective temporal resolution for high heart rate imaging without restrictions.
The Revolution CT continues GE’s commitment to even lower CT doses, with innovations such as the new Gemstone Clarity detector, a dedicated 70-kVp scan mode for pediatric use, and ASiR-V*, GE’s next generation of iterative reconstruction technology.
For the patient, the system provides a wider, more comfortable 80-cm bore and a quiet scanning experience with the new Whisper Drive system. Ultra-fast scanning with streamlined workflow makes it a suitable scanner for emergency rooms.
GE Healthcare is also introducing a new user interface based on inputs from hundreds of clinicians and technologists around the world.
