AI Technical Summary

Technical Problem

Existing medical diagnostic systems struggle to accurately integrate physiological data, such as pressure data, with intravascular imaging data and X-ray data for efficient and precise vascular catheterization procedures, particularly in diagnosing and treating coronary artery disease.

Method used

A system for tri-registering physiological data, intravascular imaging data, and extraluminal images, co-registering pressure data and intravascular ultrasound data to an angiogram, allowing for superimposed display on a longitudinal view of the vessel.

Benefits of technology

Enables physicians to quickly and accurately determine the optimal treatment path and location for interventions like stent placement by correlating pressure and imaging data along the vessel, enhancing diagnostic precision.

Abstract

The system includes a processor circuit that receives intravascular imaging data from the intravascular imaging catheter, x-ray images from the x-ray imaging device, and intravascular pressure data from the intravascular pressure-sensing guidewire. The processor circuit correlates the intravascular imaging data and the intravascular pressure data with positions along the body lumen indicated in the x-ray images. The processor circuit generates a longitudinal view of the body lumen based on the intravascular imaging data and outputs a screen display including the longitudinal view of the body lumen with a superimposed graphical representation corresponding to the intravascular pressure measurements.
