GSI Xtream is between two and eight times faster than GE’s previous generation GSI technology.
“The benefits of spectral imaging have been widely published, but it has not been broadly adopted because of the workflow limitations in the industry,” says Scott Schubert, general manager of premium CT at GE. “We think GSI Xtream is now the first technology that is able to make spectral imaging a routine application.”

Philips Healthcare’s flagship spectral CT system, the IQon Spectral CT, received FDA clearance in November 2014. It’s different from the GE and Siemens systems in that the clinicians don’t have to decide up-front whether they want spectral results for the patient.
“Spectral results are available for every patient scanned on the IQon, which helps to increase diagnostic confidence, as well as provide the opportunity to be a cost-effective resource by reducing the need for downstream testing,” says Lakshmi Gudapakkam, general manager of the diagnostic imaging business group at Philips.
The system uses a dual-layered detector, which is essentially two detectors sandwiched on top of each other. The advantage of that technique is that a spectral imaging is generated every time, according to Launders.
He adds that it's still the early adoption days of spectral CT and that its true potential remains unknown.
Toshiba Medical's Aquilion ONE -- GENESIS Edition premium CT
The cost-effective side of premium CTs
At last year’s Radiological Society of North America annual meeting, Toshiba Medical introduced its new Aquilion ONE / GENESIS Edition premium CT. The system filters the X-ray beam in a way that reduces dose and improves image quality.
Its PUREViSION Optics, PUREViSION Detector and FIRST reconstruction technology improve high contrast spacial resolution up to 129 percent while reducing dose by about 85 percent compared to the Aquilion ONE ViSION Edition.
Reconstruction times have been improved by up to 80 images per second and FIRST reconstruction is achieved in as little as three minutes per 320 images.
Three systems have been installed to date – the first at the National Institutes of Health and the other two at St. Cloud Hospital in Minnesota and Cincinnati Children’s Hospital Medical Center.
