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. 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.
The Gemstone Detector
Gemstone™ is the essential innovation that drives the high definition breakthrough. Comprised of our proprietary CT scintillator material, its exclusive garnet structure enables high-definition imaging during sub-second scanning 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.
Gemstone Spectral Imaging (GSI)
GSI’s unique and 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.
ASiR™, which comes standard on Revolution HD, is the industry’s most used iterative reconstruction technology with over 47 million patients benefiting from its use to date.
ASiR-V™ is offered as an option and is designed to reduce noise levels, improve low contrast detectability and reduce dose by up to 82% in routine imaging for all exams and all patients1,2.
Veo™ is offered as an option and is the ultimate advancement in CT image reconstruction technology. It’s also the world’s first model-based iterative reconstruction product enabling imaging less than 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.
The Data AcquisitionSystem
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 570 mA on the small focal spot and 835 mA on the large focal spot.
1. In clinical practice, the use of ASiR, ASiR-V, 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.
2. Low contrast detectability (LCD), image noise, spatial resolution and artifacts were assessed using reference factory protocols comparing ASiR-V and FBP. The LCD measured in 0.625 mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using model observer method.
