iFR Co-registration

Angiography alone is not enough to identify lesion location. Only Philips co-registers iFR1,2,3 values directly onto the angiogram giving you advanced physiologic guidance to help you see precisely which parts of a vessel are causing ischemia and determine your treatment strategy.

Final CEE consent

Decide not just whether to treat, but where to treat

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


  • Plan your procedure with physiologic guidance
  • Better discern focal, serial, or diffuse disease
  • Determine precise lesion severity and location
  • Make length measurements without a cumbersome pullback device
  • Estimate the physiologic impact of a virtual stent

Case example: iFR Co-registration workflow

  • Quickly review pressure drops and precise ischemia locations so you can plan your treatment strategy more accurately and easily 
  • Automatically co-register values in seconds onto the angiogram to give you a complete picture
  • Easily assess treatment strategy decisions with virtual stenting to ensure you achieve maximize physiologic gain and reduce guesswork

Improving PCI with iFR Co-registration

Dr. Justin Davies explains how iFR
Co-registration can identify disease location and the likely impact of PCI before you stent.

Why is iFR Co-registration unique? 
Dr. Morton Kern explains how iFR Co-registration helps him better plan his treatment strategy by combining physiology and angiography. 

Improving your treatment strategy with iFR Co-registation

Dr. Mathews reviews an ostial LCX case in which he used iFR Co-registration to plan his treatment strategy.

Transforming how we do PCI with
iFR Co-registration

Dr. Allen Jeremias explains the need to understand not just whether there is ischemia, but where it is when planning for PCI.

How are experts using iFR Co-registration in their interventions?

Quickly and easily understand lesion-specific physiology


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

Focal disease

Diffuse disease

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.

“Click and drag” length measurements help with procedural planning 

iFR and IVUS Tri-registration

Obtain easy length measurements that combine IVUS and iFR information with the angiogram to help determine if a stent will meet the procedural objectives.
