SOMATOM Definition Edge

SOMATOM Definition EdgeExceeding expectations

Confronted with increasingly complex clinical requirements and rising numbers of patients, medical institutions are expected to perform at the limits of capacity every day. SOMATOM Definition Edge helps you not only meet, but exceed these expectations by improving your institution’s process efficiency and patient outcome in all clinical capabilities – from contrast media-efficient TAVI planning to precise therapy response management, from low dose therapy control to optimized emergency care workflow.

  1. iMAR3 (iterative Metal Artifact Reduction)
    With iMAR3, surgical, prosthetic and dental fillings as well as pacemakers are not hiding insights anymore

  2. Adaptive 4D Spiral
    The SOMATOM Definition Edge features Adaptive 4D Spiral for long-range dynamic imaging of up to 48 cm

  3. Wide range for Dual Energy applications ready for routine scanning
    TwinBeam Dual Energy in combination with dose reduction techniques

  4. Optimized dose and contrast to noise ratio
    Straton® MX tubes, high power generators in combination with CARE kV and CARE Child/70kV

  5. Uncompromised diagnostic outcome at low dose

    Stellar detector, the first fully integrated detector

  6. Optimized spectrum for dose efficiency
    Tin Filter in combination with all dose reduction techniques

  7. Fast scanning routine
    230 mm/s, 0.28 sec per rotation and 1.7 pitch even for demanding cases like obese or pediatric patients
  8. Exceptionally low radiation levels, less noise, natural image impression
    ADMIRE2 - routine ready with fast image reconstruction

Features & Benefits

CT Scanner - SOMATOM Definition Edge - Cardiology

Making highly precise plaque differentiation part of your clinical routine will not only improve patient outcome, but also increase process efficiency, as unmistakingly clear findings will drastically reduce the number of discussions about the state of the plaque. Covering greater volumes faster, improving contrast media efficiency in low kV TAVI planning, and introducing reliable, high-speed triple rule-out scanning will expand your institution’s clinical capabilities – and help you exceed the expectations that come with increasingly complex cardiac cases.

Metal artifact reduction with SOMATOM Definition Edge and its clinical outcome at BG Klinik, Tübingen.

Emergency scanning is as much about time as it is about image quality. You will be able to optimize process efficiency with solutions that let you not only improve emergency workflow but also substantially reduce door-to-image time, from pediatric to obese patients. SOMATOM Definition Edge enables excellent tissue evaluation, allows for the scanning of pediatric and obese patients without dose discussions, and facilitates a minimized sedation and breath hold with a pitch of 1.7 at 23 cm/sec, so you can reduce door-to-image and optimize your overall emergency workflow.

TwinBeam Dual Energy

With around a quarter of therapies adjusted after response assessment, a key challenge in oncology is finding out if the tumor is responsive to therapy. Making therapy response assessment faster, more reliable, and easier to manage, will directly benefit your workforce as well as your patients. Expanding your clinical capabilities with improved, low dose therapy control, and CT-based early tumor identification will benefit your institution both in daily practice and in the long run: the more reliable and dose-efficient the technology gets, the greater its role will become for preventive care, as well.
Find out how ADMIRE2, Tin Filter technology, Adaptive 3D Intervention Suite, TwinBeam Dual Energy and True Dual Energy CT Applications make it happen.
