  • Auto Image Paste

    The Definium 646 HD provides seamless long bone and spine imaging at the wall stand and table. Enhanced with AutoSpine, an intelligent pasting algorithm, Auto Image Paste follows the contour of the spine for vertical equalization enabling a natural balance of brightness and contrast along the patent body.


  • Standalone Helix™ Workstation

    The standalone Helix Workstation helps support patient care by allowing technologists to process, edit and reprocess images around exam demand and without system impact.

    The Helix™ workstation:
    • Accepts images from both fixed and mobile x-ray systems
    • Pushes any GE HD x-ray image to the Helix workstation, perform reprocessing and push to PACS
    • Enables fast reprocessing and reconstruction with a powerful GPU processor
    • Provides QuickTools customizable toolbar for most frequently used operations

  • Live Streaming Camera

    Definium 646 HD with live streaming video keeps technologists eyes on the patient for a greater portion of the exam helping to monitor patient safety and potentially reduce rejects that stem from patient motion.

  • Extraordinary anatomical detail at low dose in every X-ray image.

    Helix™ 2.0 Advanced Image Processing algorithms harness the full high-resolution power and exceptional dose efficiency of FlashPad HD detectors to deliver outstanding clarity and
    extraordinary anatomical detail where it matters most.

  • Up to 40% improvement in detectability of fine structures1

    The power of Helix™ 2.0 advanced image processing coupled with FlashPad HD improves small detail detectability by up to 40%1 thanks to ultra-high resolution and enhanced noise control.

  • Critical Care Suite

    GE Healthcare’s X-ray systems are “Getting Intelligence!”, with Critical Care Suite1 applications dedicated to bringing AI capabilities at the point of care to help the clinical care team prioritize cases that present critical findings in frontal chest X-ray images.

  • Consistent brightness and contrast

    Helix™ 2.0 with AI-driving automated brightness and contrast delivers improved consistency across variations in dose exposure with auto window width and window level and enhanced contrast restoration.

  • Double your resolution

    The FlashPad HD detectors pack four times more pixels per area for sharp X-ray images, plus they capture extraordinary anatomical detail at low dose. Available in 10 in x 12 in , 14 in x 17 in and 17 in x 17* in standard cassette sizes.

    * The 17 in x 17 in detector is currently only available on fixed systems .

  • Exceptional dose efficiency for your tiniest patients (and the large ones too)

    The ultra-high dose efficiency helps enhance diagnostic imaging quality at low dose for all patient types.

  • Excellent handling of metal implants

    Clear bone-metal interface without halo artifact.
