QCA can be extended with research functionality. QCA research has specific additional functionality for both single vessel and bifurcation analysis. Drug Eluting Stent (DES) analysis enables the user to evaluate restenosis and edge effects in pre-, post- and follow-up studies. With User Defined Subsegments (UDS), the vessel of interest can be divided in multiple subsegments and the curvature of these subsegments can be determined. UDS can for example be used in studies with biodegradable stents.
With the Bifurcation 6- and 11-Segment Model (BSM) implanted bifurcation stents can be quickly compared in pre-, post- and follow-up studies.
