    Only Philips co-registers iFR values1,2,3 directly onto the angiogram, allowing you to see precisely which parts of a vessel are causing ischemia.

    iFR Co-registration overview

    ifr-coreg-overview

    With iFR Co-registration there is no need for hyperemic drugs, no need for time consuming pullback devices and no need for guesswork.

     

    • Mapping of physiologic drops onto the angiogram to better discern focal, serial or diffuse disease
    • Precise lesion severity, location and length assessment
    • Make length measurements without a cumbersome pull back device
    • Physiologic impact of a virtual stent
    • Plan your procedure with physiologic guidance

    Understand lesion-specific physiology

     

    iFR Co-registration graphically displays the iFR drop along the angiogram, highlighting which portion of the vessel is ischemic.

    Make length measurements without a cumbersome pull back device

     

    iFR Co-registration is calibrated for distance, so with a simple manual pullback you can make measurements on the angiogram and trend line.

    iFR and IVUS tri-registration

     

    After placing a stent in the mid-vessel, the physician is deciding if they needs to treat the proximal LAD. Tri-registration shows an iFR value of 0.98 and a cross section of 7.9 mm2 by IVUS. The physician decides this intervention is complete.
