Gemstone* is the essential innovation that drives the high definition breakthrough. Comprised of our proprietary CT scintillator material, the Gemstone is the first new detector material in 20 years. Its exclusive garnet structure enables high-definition imaging of 0.23 mm and fast kV switching. Gemstone’s recovery time is four times faster than comparable detectors, and its primary speed is 100 times faster than competitors.
How it works
Enabled by the Gemstone detector, GSI’s unique fast-kV switching technology offers 0.25 msec temporal sampling of 140 kV and 80 kV at full 50 cm field of view (FOV) with near perfect anatomical registration – even at dose levels the same as single standard acquisition. This acquisition allows for reconstruction and viewing of monochromatic images from 40 keV to 140 keV.
Modern imaging intelligence
Revolution* GSI features Smart Technologies, a suite of intelligent CT tools designed to help you achieve your imaging goals with improved efficiency and expanded applications, all while delivering diagnostic confidence with lower levels of radiation.
Smart Dose with kV Assist provides automated kV and mA recommendations allowing users to tailor protocols to each patient, clinical indication and each scan area. Organ Dose Modulation automatically reduces dose for superficial tissues such as the eyes and anterior chest, creating a virtual shield for sensitive anatomy.
Smart Cardiac with SnapShot* Assist helps you optimize cardiac scanning for individual patients based on their specific parameters.
Smart Spectral with GSI Assist helps you optimize GSI protocols to your patient and clinical needs.
Leading-edge technology throughout the image chain
Leading edge clarity requires innovation throughout the image chain — and across every variable of image development. With technologies and features that set new benchmarks for image clarity, high-definition CT opens the door to new noninvasive diagnostic procedures and innovative techniques for challenging conditions.
Data acquisition system
GE Healthcare’s Volara* DAS technology reduces electronic noise for outstanding image quality in both high and low signal areas of the anatomy. It’s also an integral part of the system’s improved spatial resolution across the entire field of view and delivers 2.5 times more views per rotation to improve x and y axis resolution and reduce artifacts.
The Performix* HD Tube enables the visualization of more detail with increased data sampling, ultra-fast kV switching and a maximum mA of up to 570mA on the small focal spot and 835mA on the large focal spot.
ASiR*, which comes standard on Revolution GSI, is the industry’s most-used iterative reconstruction technology with over 47 million patients benefiting from its use to date.
In addition, Revolution GSI offers Veo* as an option, the ultimate advancement in CT image reconstruction technology and the world’s first model-based iterative reconstruction product, enabling imaging under 1 mSv with profound clarity. With Veo, lower noise and higher resolution can be achieved within a single image. At the same time, significant dose reduction capabilities are now available, opening up new possibilities for challenging cases and sensitive patients. This breakthrough is changing the way physicians use CT imaging, delivering a combination of high-performance images and low dose that was previously unthinkable1.
1. 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 physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
