Ultrasound Imaging Controller ROI Selection for Cardiac Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasound imaging apparatuses face challenges in efficiently and quickly recognizing cardiac structures, particularly in displaying and analyzing cardiac long and short axis cross sections and three-dimensional images for accurate diagnosis.
Innovation Solution
The ultrasound imaging apparatus includes a controller that allows for the selection and display of region of interest (ROI) images, enabling the user to focus on specific cardiac cross sections and three-dimensional views, with a touch panel interface for inputting commands and displaying preset ROI images, facilitating efficient recognition of cardiac structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cardiac images (long axis, short axis, 3D) are displayed simultaneously, then diagnostic accuracy is improved, but device complexity increases
Solution Approach 1:
The display screen is segmented into multiple regions, with each region showing a different cardiac image (long axis cross section, short axis cross section, and 3D image). This allows simultaneous display of multiple images without requiring a single complex display system, as each segment can be independently controlled and optimized.
Solution Approach 2:
The patent transitions from displaying images sequentially or in separate views to displaying them simultaneously in a multi-region spatial arrangement. By utilizing the two-dimensional screen space more efficiently through dimensional division, the system presents multiple cardiac views without increasing physical device complexity.
2Ease of operation
If ROI selection interface is provided, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The ROI selection interface is merged with the cardiac image display regions. Users can directly interact with the displayed images to select ROIs, combining the imaging function and interaction interface into a unified system. This eliminates the need for separate control interfaces while maintaining ease of operation.
Solution Approach 2:
The system provides self-service functionality by allowing users to directly select ROIs on the displayed images through the touch panel. The interface automatically processes user selections and updates the display accordingly, eliminating the need for complex manual configuration or separate control procedures.
3Ease of operation
If touch panel interface is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The touch panel serves as an intermediary between the user and the image processing system. It provides a natural, intuitive interface for selecting ROIs and controlling image display, while the controller mediates between touch inputs and image processing operations. This intermediary layer simplifies user interaction without requiring complex internal system changes.
