See beyond the conventional to the next generation of multi-energy CT
With Philips true detector-based spectral CT, scan as you normally would for fast, low-dose conventional and spectral data. Detector-based, multi-energy CT acquires scans within a single exposure and without special scan modes, and with results on-demand. No longer do you have to choose between viewing anatomical structures and identifying material composition.
More than 40 years of CT innovation
Discover how the evolution of Philips continues to improve people’s lives with spectral-detector results in CT imaging.
Conventional CT
1986: Introduction of the I.Q. CT imaging system scanner
The I.Q. was the industry’s first slip ring scanner with an on-board X-ray generator, which revolutionized CT (by making it a faster acquisition) and opened the way for spiral scanning, which transformed CT. Spiral scanning transformed CT from being a very slow modality to a faster one.
With the advent of the multi-slice scanner, the next transformation of CT introduced new imaging such as cardiac imaging and an even faster mechanism.

Why Spectral CT?
Unlike traditional CT images, spectral-detector CT images capture spectral information 100% of the time —without special planning or set-up. That means you can analyze the spectral data in any image retrospectively, using a variety of spectral viewing tools. You can, for example, adjust the monoenergetic level or get Zeffective maps.

How spectral detector works
Spectral detector simultaneously absorbs and differentiates high and low energy from a single polyenergetic X-ray beam. Spectral results are acquired within a single scan without the need for special modes.
Spectral Results Anytime, Anywhere. Single DICOM entity contains sufficient information for retrospective analysis.
Detector-based spectral CT simultaneously absorbs high and low energies in the same time and space.
Key features of spectral detector CT
Spectral CT helps me objectively differentiate contrast staining from hemorrhage, obviating the need for additional follow up scanning and prolonged patient observation, which can result in reduced costs and radiation exposure to patients.1,2
