AI Technical Summary

Technical Problem

Conventional ultrasound imaging systems for transcatheter procedures, such as TEE, require significant vigilance and constant monitoring by multiple specialists due to the difficulty in visualizing anatomical features, leading to cognitive burden and stress during procedures like mitral valve replacement, as these features are often shadowed or cropped out of view.

Method used

A 3D model is generated based on ultrasound data to track markers and instrument position, allowing for real-time updating and display of critical anatomical features and instrument position, with notifications generated based on distance and alignment thresholds to ensure safe navigation.

Benefits of technology

Reduces cognitive burden and enhances procedural safety by providing real-time visual aids and alerts, enabling precise instrument placement and avoiding anatomical hazards during transcatheter procedures.

Abstract

An example method includes receiving ultrasound (US) data from an echocardiogram probe for a region of interest for of the intracardiac transcatheter procedure. The method also includes constructing a three-dimensional (3D) model of the region of interest based on the US data. The 3D model tracks a set of markers, and a marker of the set of markers has a position on the 3D model. The method additionally includes displaying an output image. The output image comprises an output US image of a portion of the region of interest, overlaid with a portion of the 3D model corresponding to the portion of the region of interest. The portion of the 3D model comprises the marker. In some examples, the marker tracks a stationary position such as a rapid pacing position associated with a feature, including while the feature is in motion.
