Embodiment approach

[0118] The systems and methods described herein, provide diagnostic information to support imaging needs before and after interventions that are similar to VFR for bifurcations, BVS, for other complex conditions (e.g. tandem lesions / diffuse disease) relevant to specific clinical applications. Implementations include the following features:

Abstract

In part, the invention relates to an intravascular data acquisition system and software-based visualization and display of intravascular data relating to detected side branches and detected stent struts. A user interface, such as a slider, a switch key, a button, a domain, or other interface, may be used to define a level of stent adherence failure to specify how indicia are displayed relative tothe detected stent strut. Furthermore, the present invention relates to a method of automatically providing a two-dimensional or three-dimensional visualization adapted to evaluate the location of a side branch and / or guidewire during a stent implantation procedure. The method may use one or more calculated side branch positions, branch retrieval angles, one or more stent strut positions, and oneor more lumen profiles.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 196,997, filed July 25, 2015. technical field [0003] The present invention generally relates to intravascular measurement and feature detection and related diagnostic methods and devices. Background technique [0004] Coronary artery disease is one of the leading causes of death worldwide. Better ability to diagnose, monitor and treat coronary artery disease could have important implications for saving lives. Intravascular optical coherence tomography (OCT) is a catheter-based imaging modality that uses light to peer into the walls of coronary arteries and generate images for study. Using coherent light, interferometry, and micro-optics, OCT provides high-frequency in vivo tomography with micron-scale resolution within diseased vessels. Observation of subsurface structures at high resolution using fiber optic probes makes OCT particularly usefu...
