Spectral ct masthead

See beyond the conventional. Discover 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.

Transformed spiral scanning

1986: Introduction of the IQ scanner

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.

Innovations of CT systems

1990’s: Multi-slice scanner, simulator, and advanced tube technology

Philips adopted a human-centered approach to product design which harmonized and integrated all aspects, improving patient experience and throughput.

Receiving conventional CT

2016: Philips IQon - the first spectral detector CT

Spectral detector CT transformed conventional CT to a quantitative CT. The second-generation Philips Spectral CT 7500 receives an Aunt Minnie Award for Best New Radiology Device in 2021.

Why spectral

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.

A conversation with Oren Zarchin

Spectral Results Anytime, Anywhere. Single DICOM entity contains sufficient information for retrospective analysis.

How Spectral CT technology works

Detector-based spectral CT simultaneously absorbs and differentiates high and low energy, in a single polyenergetic X-ray beam at the detector level.

Key features of spectral detector CT

Dr Douek
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
