3D Cross-Section Positioning for Left Atrial Appendage Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for measuring the shape of the left atrial appendage entrance part and surrounding site using two-dimensional ultrasound images are labor-intensive and lack precision, necessitating manual operation and potentially inaccurate measurements.
Innovation Solution
A medical image diagnosis apparatus that generates a three-dimensional model of the target site using three-dimensional data, calculates positions of recommended cross-sections based on the model, and displays these positions to facilitate precise and automated cross-section setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to set cross-sections for shape measurement, then the operator can control the measurement process, but the workload becomes large and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically generating a three-dimensional model from ultrasound images before the measurement process. The cross-sections are pre-identified and positioned based on the three-dimensional model, eliminating the need for manual setting during the measurement process and significantly reducing operator workload and time consumption
Solution Approach 2:
The measurement system performs self-service by automatically identifying and positioning cross-sections without requiring manual intervention. The three-dimensional model generation and cross-section identification processes are executed autonomously by the system, allowing the measurement to be performed with minimal operator involvement
2Measurement precision
If two-dimensional ultrasound images are used for shape measurement, then the measurement process can be performed with existing equipment, but the precision level is insufficient
Solution Approach 1:
The system transitions from two-dimensional ultrasound images to three-dimensional modeling by generating a three-dimensional model of the left atrial appendage. This dimensional change enables precise measurement of complex three-dimensional structures while maintaining compatibility with existing two-dimensional ultrasound equipment, thus improving measurement precision without requiring entirely new hardware
Solution Approach 2:
The three-dimensional model serves as an intermediary that bridges the gap between two-dimensional ultrasound images and the required precise measurements. It processes the two-dimensional image data into a three-dimensional representation that can be accurately measured, thereby improving precision without directly requiring complex three-dimensional imaging equipment
