Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If 3D/4D contrast-enhanced imaging is performed with high imaging velocity, then real-time observation capability is improved, but the amount of data processing required increases beyond system capabilities
Solution Approach 1:
The patent segments the imaging process into multiple adjustable parameters including number of transmissions, line density, and region of interest (ROI) settings. By dividing the overall imaging task into controllable components, the system can process data at high velocities without overwhelming the computing system, as each parameter can be independently optimized to balance speed and processing load.
Solution Approach 2:
The patent implements dynamic adjustment of imaging parameters based on real-time system performance and clinical needs. The imaging velocity and related parameters (transmissions, line density, ROI) are made dynamically configurable, allowing the system to adapt processing demands to match both the imaging speed requirements and the actual data processing capabilities of the system.
2Speed
If imaging parameters are adjusted to increase imaging velocity, then real-time observation is improved, but image quality or data completeness may deteriorate
Solution Approach 1:
The patent systematically varies multiple imaging parameters (number of transmissions, line density, ROI range) to achieve different imaging velocities while maintaining acceptable image quality. By changing these parameters in coordinated ways, the system can select optimal settings that balance imaging speed with the completeness and quality of the acquired data for reliable diagnosis.
3Manufacturing precision
If the number of transmissions and line density are increased to improve image quality, then data processing load increases, but imaging velocity decreases
Solution Approach 1:
The patent applies partial action by allowing users to select ROI (region of interest) that focuses processing resources on only the necessary portions of the imaging volume. Instead of processing entire volumes at maximum detail, the system processes only the relevant regions with appropriate transmission and line density settings, thereby maintaining image quality in critical areas while reducing overall processing load and improving effective imaging velocity.

AI summary
Disclosed are 3D/4D contrast-enhanced ultrasound imaging (CEUS) apparatus, 3D/4D CEUS imaging methods and media. The method comprises: receiving an input for selecting a 3D/4D contrast-enhanced imaging mode; receiving an input for setting an imaging velocity including a first imaging velocity and a higher second imaging velocity; controlling the apparatus with an imaging parameter associated with the selected imaging mode and the set imaging velocity to achieve imaging with the selected imaging mode in the set imaging velocity, wherein an association between the imaging parameter and the imaging velocity allows that an amount of data required to generate images per volume using the first imaging velocity is greater than that using the second imaging velocity. In this way, a desired imaging mode and imaging velocity can be chosen freely and an imaging parameter can be selected pointedly, meeting real-time observation needed by doctors with limited data processing capability and various probes.
