    Announcing FreePlane
    Navigation technology

    • …now with Adaptive Needle Recognition
      a new era in procedural guidance
    Read more

    eZGuide™, a revolutionary needle guidance technology.

    Now, clinicians using ultrasound guidance for procedures, can accurately visualize the needle track and the needle tip position, in any chosen plane, using eZGuide’s onscreen display with color coding. The alignment of the needle and the position of the tip relative to the imaging plane are always in view, allowing the user to identify the correct needle trajectory, prior to puncturing the patient’s skin and maintain the chosen route to the target anatomy.

    Before using eZGuide™, calibration is required for your needle of choice.
    Some of the most commonly used needles have already been calibrated and they are added as an easy selection on the eZono® 4000 menu. A list of the currently qualified needles and vendors is available in this pdf file:
    View pdf

    If your preferred needle does not appear on this list, please contact eZono® for details on needle calibration for non listed vendors.


    FreePlane Navigation
    with Adaptive Needle Recognition:

    eZGuide™ is performed free hand, and functions for any plane procedures. Whilst conventional needle guidance technology restricts the choice of clinicians, to either in-plane or out of plane, eZGuide™, allows the clinician to choose the optimal path of approach to the target area.

    Now with the latest eZGuide™ Adaptive Needle Recognition software, clinicians have the flexibility to use preferred needles whenever possible*, and are not limited to proprietary needles. eZGuide™ ANR automatically calibrates the eZono® 4000 system for the currently selected needle so clinicians are fully aware of the capabilities with regard to needle properties, navigation and depth of penetration prior to starting an invasive procedure, providing the means for the clinician to improve the safety and efficiency of the procedure.

    *  Needles must be made of materials that can be magnetized



    The Needling Challenge

    The challenge facing clinicians using ultrasound guidance is developing the skills to manipulate both the needle and transducer to achieve the correct alignment and visualize the needle. Even with good technique, the needle is frequently identified more on tissue movement rather than good visualization and the user is restricted to ‘in plane’ techniques.

    It has been reported that most problems associated with needle guidance techniques is failure to recognize the needle tip.

    With eZGuide™ we overcome these challenges with on screen navigation that identifies and displays the needle path, for any plane techniques, and accurately pinpoints the needle tip.

    Tilo, Quality Engineer

    I like working at eZono because Quality is an integral part of most of eZono’s activities. We are involved at each stage of the product development life cycle, we test our final products with partners like Carl Zeiss, and ensure our supply and distribution partners achieve the highest standards. I am particularly proud that we consistently score highly with DEKRA, one of the toughest auditors in the Medical devices industry…”

    Desi, graphic designer

    Our team makes the visual content for eZono’s CUE CARDS and GUI. My challenge is working closely with doctors and engineers to get the pictures, animations and video just right. It’s really satisfying using my skills to help our customers learn more and use our products intuitively. I also try to make them beautiful…

    Huang, software tester

    “My job is to break the software! That is before it is released to any customer. We continually run software tests at all levels of product development and in fact 40% of our software code is for testing purposes alone. We are paranoid about ensuring the software keeps going night and day for our customers and proud that our field failure rate is well below the industry average…”

    Emilio, research engineer

    I feel very lucky to work on making doctors lives easier with technology. The projects we work on are very exciting and challenging from the technical point of view. It’s also fun working with research partners like the Fraunhofer institute too…
