Asteion S4: The future of CT right at your fingertips

The Asteion S4 is a unique combination between economy and quality. Unique as Asteion S4 is the only 4-slice CT using 0.5 mm detector technology with excellent low contrast as well as high contrast resolution properties.

Unique as Asteion S4 is the only 4-slice of it's kind capable of tilted helical scanning. Image quality for tilted scans is guaranteed to be of high standard as cone beam correction is standard for tilted helical scanning using the patented TCOT true cone beam reconstruction method.

Scanning has never been as easy as with the new high efficiency Guided Mode. Guided Mode gives experienced users the possibility to scan even more efficient and allows new users to get quickly get acquainted with the new Asteion S4 system. No more looking for clues. Asteion S4 is the best solution for efficient scanning. Unique even as Asteion S4 is the only 4-slice CT equipped with SUREExposure, the only method independent of the patient's age, weight or kV value used. Asteion S4 always delivers the optimum dose.
