Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-dimensional transesophageal echocardiography (TEE) and intracardiac echocardiography (ICE) images lack spatial information, making it challenging to accurately locate the target puncture point and track the catheter tip during percutaneous interventions.
Innovation Solution
A method and system utilizing intracardiac echocardiography (ICE) image analysis to detect target puncture areas, simulate geometric changes, and generate a planning scheme for interventional surgery, including three-dimensional anatomical modeling and real-time tracking.

Engineering Contradiction Analysis
1Object-affected harmful factors
If two-dimensional TEE or ICE images are used for guidance, then real-time monitoring without X-ray exposure is achieved, but spatial information is lost making accurate puncture point localization difficult
Solution Approach 1:
The patent transforms two-dimensional echocardiography images into three-dimensional anatomical models, adding the spatial dimension to restore depth information. This allows accurate localization of puncture points on the interatrial septum while maintaining the advantage of avoiding X-ray exposure.
Solution Approach 2:
The patent creates a virtual three-dimensional copy of the cardiac anatomy from multiple two-dimensional echocardiography images. This digital twin provides spatial context and anatomical relationships, enabling precise puncture point identification without requiring direct three-dimensional imaging or X-ray exposure.
2Measurement precision
If traditional X-ray guidance is used for septal punctures, then accurate puncture site localization is achieved, but exposure to X-rays occurs
Solution Approach 1:
The patent introduces three-dimensional echocardiography-based anatomical models as an intermediary between the operator and the actual puncture procedure. This intermediary provides accurate spatial information and anatomical guidance, replacing the need for X-ray fluoroscopy while maintaining puncture accuracy.
Solution Approach 2:
The patent replaces the mechanical/radiological system (X-ray fluoroscopy) with an acoustic-based system (echocardiography with three-dimensional reconstruction). This substitution eliminates ionizing radiation exposure while providing equivalent or superior anatomical guidance through ultrasound imaging.
3Speed
If two-dimensional images are used for catheter tracking, then real-time monitoring is achieved, but accurate catheter tip tracking is difficult
Solution Approach 1:
The patent enhances catheter tracking by adding three-dimensional spatial context to the monitoring system. By overlaying catheter position data onto three-dimensional anatomical models, the system maintains real-time monitoring capability while dramatically improving the accuracy of catheter tip localization and orientation.

AI summary
Methods and systems for guiding interventional surgery are provided. The method includes receiving a plurality of intracardiac echocardiography (ICE) images of a target object acquired during a preset period, analyzing of the plurality of ICE images to obtain image analysis results, and generating an interventional surgical plan based on the image analysis results to guide the interventional surgery. This method conducts image analysis on ICE image before puncture to plan the interventional surgery, thus identifying the optimal puncture angle, depth, and timing for the interventional surgery. The method can help conduct real-time detection and tracking of the puncture process, identifying and mitigating potential risks during the surgical process to improve the success rate of the surgery. Furthermore, continuous assessment and management of possible complications can be carried out through postoperative evaluation to comprehensively reduce the risk of the interventional surgery and enhance its effectiveness and safety.
