Siemens Somatom Definition AS 128

Siemens Somatom Definition AS 128 CT Scanner for Sale

The Siemens Somatom Definition AS 128 CT scanner is a 128-slice CT system designed to support high-resolution imaging with advanced dose protection and adaptable workflow configuration. As a pre-owned CT platform, it offers balanced performance for cardiac, trauma, oncology, and pediatric imaging while maintaining efficient daily operation.

If you are looking to buy a Siemens Somatom Definition AS 128 CT scanner, this system provides scalable clinical capability with controlled radiation management and installation flexibility. 

Who is this system a good fit for?

The Somatom Definition AS 128 is well suited for:

• Hospital radiology departments with mixed case volumes
  
• Emergency and trauma units requiring fast whole-body scanning
  
• Oncology centers performing dynamic and follow-up imaging
  
• Facilities upgrading from 64-slice systems
  
• Providers needing adaptable installation and room flexibility

For these environments, a used 128-slice CT system can expand diagnostic capability while keeping investment predictable.

Managing variability across patient types

Daily CT imaging includes pediatric, cardiac, trauma, and bariatric patients. The Siemens Somatom Definition AS 128 CT scanner is designed to adapt to these different clinical conditions without compromising image quality.

With a 128-slice detector and fast acquisition, the system can perform a full-body scan of up to 2 meters in approximately 10 seconds. This supports rapid trauma evaluation and reduces motion-related artifacts.

High temporal resolution of 150 ms combined with thin-slice imaging supports consistent results, even in patients with elevated heart rates or limited breath-hold capacity.

Dose protection and radiation management

The Somatom Definition AS 128 integrates multiple dose management technologies to help maintain low radiation exposure while preserving diagnostic clarity.

Key technologies include:

• CARE Dose4D for real-time tube current modulation
  
• Adaptive Dose Shield to reduce unnecessary pre- and post-spiral exposure
  
• STRATON X-ray tube design supporting efficient dose control

Adaptive Dose Shield can reduce radiation exposure during routine examinations by limiting unnecessary beam exposure before and after spiral scanning.

These tools help maintain consistent image quality at optimized dose levels.
