Intraluminal Imaging Landmark Detection for Lesion Assessment

Solution Overview

Problem

Current intraluminal imaging systems require manual selection and analysis of multiple frames to identify landmarks and assess lesions, which is time-consuming and prone to errors, leading to misjudgment of lesion extent.

Innovation Solution

An intraluminal imaging system that automatically identifies and measures landmarks, such as tissue borders and lesions, within a lumen, displaying these measurements alongside intraluminal images to facilitate accurate lesion assessment and stent placement recommendations.

AI summary

Systems, devices, and methods are provided to determine and visualize landmarks with an intraluminal imaging system for lesion assessment and treatment. An intraluminal imaging system may be configured to receive imaging data from an intraluminal imaging device, generate a set of image frames using received imaging data, and automatically calculate a luminal area associated with the body lumen for each of the image frames. The calculated luminal area and a longitudinal view of the body lumen may be displayed to a user on a display device.
