Siemens SOMATOM DEFINITION AS CT Scanner: Advancing Imaging Technology for Precision Diagnosis and Safety

The Siemens SOMATOM DEFINITION AS CT scanner represents a significant advancement in imaging technology, offering unparalleled precision and safety in diagnostic procedures. Unlike conventional CT systems, the SOMATOM Definition AS takes a pioneering approach by eliminating the use of lead as a counterbalance for rotating components. Lead, a toxic element, is replaced entirely, except for a minimal amount required for radiation shielding and shaping. This innovation underscores Siemens' commitment to environmental responsibility and patient well-being.

Reducing energy consumption and radiation dose without compromising image quality posed a formidable challenge. However, through innovative engineering and technological breakthroughs, Siemens has achieved remarkable results. The implementation of an adaptive dose shield, integrated with the x-ray tube, ensures that unnecessary radiation is effectively blocked, leading to an average dose reduction of approximately 15%. Moreover, energy savings of up to 30% for standard examinations have been realized, contributing to both environmental sustainability and operational efficiency.

In addition to enhancing safety and efficiency, the SOMATOM Definition AS prioritizes sustainability throughout its lifecycle. Contactless power and data transmission mechanisms not only minimize the risk of abrasion and dust accumulation but also extend the longevity of the system. Furthermore, meticulous documentation of all materials used in the product and packaging, along with clear labeling for recycling, underscores Siemens' commitment to responsible waste management and resource conservation.

The SOMATOM Definition AS is designed with end-of-life considerations in mind, facilitating high-quality recycling and refurbishment of components. Rigorous adherence to EU directives ensures compliant product take-back programs, enabling more than 98% of materials to be returned to the recyclable materials stream. Moreover, comprehensive environmental product declarations are readily accessible online, empowering stakeholders with transparent information to make informed decisions regarding sustainability.

The Siemens SOMATOM DEFINITION AS CT scanner incorporates cutting-edge FAST CARE technology, prioritizing both user and patient safety by applying the lowest radiation dose possible. Through Combined Applications to Reduce Exposure (CARE), this system offers an exceptional dose protection portfolio, ensuring the highest level of radiation protection while maintaining excellent image quality. This comprehensive approach satisfies the imperative for minimal radiation exposure while delivering precise diagnostic results, all seamlessly integrated into the scan process for enhanced workflow efficiency.

Patient-centric imaging is at the core of Siemens' approach to healthcare, particularly concerning radiation protection. The CARE Dose4D technology, proven over decades, provides real-time dose modulation, ensuring outstanding image quality with minimal radiation exposure for each patient. Building upon this foundation, CARE kV introduces a new dimension by automatically adjusting voltage and other scan parameters based on individual patient characteristics and the selected examination type. This intelligent automation ensures optimal dose efficiency in every scan, providing clinicians with confidence in diagnosis while prioritizing patient safety.

In pediatric imaging, the SOMATOM DEFINITION AS offers dedicated protocols with 70 kV scan modes through its unique STRATON X-ray tube technology. This feature, known as CARE Child, is included as a standard component with every scanner. CARE Child's specialized protocols and dose modulation curves enable safe and effective imaging of even the most vulnerable patients, ensuring that pediatric scans can be performed with confidence and without compromising on image quality or safety standards.

The Siemens SOMATOM DEFINITION AS CT scanner achieves higher resolution and reduces artifacts through its innovative technology. By enabling simultaneous acquisition, this system doubles the number of overlapping slices, resulting in increased longitudinal resolution and reduced spiral artifacts regardless of the selected pitch. This approach not only enhances resolution in the z-direction but also offers greater flexibility, as it can be applied across various scan modes. Consequently, the scanner acquires twice the number of slices with fewer artifacts, thereby delivering images of superior quality.

Moreover, the scanner effectively eliminates windmill artifacts, a common occurrence in spiral CT examinations of the head, neck, and thorax. These artifacts, often seen in CT angiography examinations for aneurysms, hindered diagnostic accuracy and clarity. However, with the implementation of z-Sharp's double z-sampling technology, windmill artifacts are effectively prevented. This breakthrough innovation removes the restrictions imposed by traditional methods, ensuring that CTAs of critical areas like the carotid arteries and the circle of Willis can be routinely performed at high pitch without compromising image quality or diagnostic integrity.
