Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ultrasound systems display three-dimensional medical images from predetermined cross-sections only, then the system complexity is reduced, but the measurement precision and diagnostic accuracy deteriorate due to limited viewing angles
Solution Approach 1:
The patent implements dynamic rendering capabilities that allow the display system to adaptively generate three-dimensional medical images from multiple predetermined directions based on user interaction. The rendering apparatus dynamically adjusts the display content according to viewer tools and selection areas, transforming a static display system into a dynamic one that provides precise observation from various angles without requiring complete system redesign
Solution Approach 2:
The patent segments the volume data into multiple predetermined cross-sections and renders each from specific directions (e.g., first direction and second direction perpendicular to each other). This segmentation allows the system to manage complexity by processing data in manageable sections while providing comprehensive viewing capabilities through multiple predetermined rendering directions
2Adaptability or versatility
If the ultrasound system generates and displays only three-dimensional ultrasound images of predetermined cross-sections, then the ease of operation is maintained, but the adaptability deteriorates as users cannot observe desired portions at various angles
Solution Approach 1:
The patent pre-divides the volume data into multiple predetermined cross-sections and prepares rendering configurations for multiple directions in advance. When users interact with the display, the system retrieves and displays pre-prepared rendering results from appropriate directions, eliminating the need for real-time complex calculations while maintaining operational simplicity and providing versatile viewing angles
Solution Approach 2:
The patent creates virtual copies of the volume data organized into multiple predetermined cross-sections, each ready for rendering from specific directions. Users can switch between different viewing perspectives by selecting appropriate cross-sections and rendering directions, effectively copying the data structure to enable multiple viewing angles without adding computational complexity during interaction

AI summary
A method of displaying a medical image includes displaying a first image that is generated by rendering volume data of an object in a first direction, displaying on the first image a viewer tool for generating a second image, wherein the viewer tool indicates a section of the object, generating the second image by rendering sub-volume data included in the volume data in a second direction which is different from the first direction and indicated by the viewer tool, and displaying at least a part of the second image.
