Revolutionary needle guidance 

eZGuide® is a revolutionary needle guidance technology available with the eZono®5000. eZGuide® enables the precise display of the needle tip and path for ultrasound-assisted applications, by having always a display of the relative position of the needle to the ultrasound plane.

Clinicians are in full control of the procedure!

Clinicians face many challenges when performing ultrasound guided procedures. And 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.

eZGuide® requires NO expensive hardware; NO specialty cannulas; NO special cannula sizes; NO changes in clinical procedure.

Free Plane 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 procedures, eZGuide®, allows the clinician to choose the optimal path of approach of the needle to reach 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® Adaptive Needle Recognition software automatically calibrates the eZono®5000 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 that clinicians face while 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 from tissue movement rather than good visualization of the ultrasound reflection of the needle. The user is frequently restricted to ‘In-Plane’ techniques. It has been reported that most problems associated with needle guidance procedures are related to 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.
