See the difference spectral-detector CT can make


With Philips true detector-based spectral CT, scan as you normally would for fast, low-dose conventional and spectral data. Detector-based spectral 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.

One case, two ways


To illustrate the power of spectral-detector CT, we present two hypothetical patients with identical health profiles, both complaining of abdominal pain. Their doctors schedule CT scans to learn more. One patient undergoes a conventional CT scan, while the other has a spectral-detector CT scan. The process is the same for both patients, and the workflow is nearly identical for the hospital staff.

Each CT scan produces a conventional CT image that shows anatomical structures in the abdomen.

But what if one view isn't enough?


In this hypothetical example, the radiologists need more information about a visible mass in the pancreas in order make a confident diagnosis.

With a traditional CT, if the image is inconclusive, the patient may be asked to return for an additional scan.

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.

Key features

How it 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.

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.
