Engineering Contradiction Analysis
1Loss of information
If multi-modality and multi-source data are combined into the same 3D representation, then information completeness is improved, but clarity and interpretability deteriorate due to information overload
Solution Approach 1:
The patent segments multi-modality data into distinct volumetric datasets, each processed independently with its own optical properties. This allows comprehensive information retention while enabling selective visualization through transfer function assignments, preventing information overload by organizing data into manageable, independently controllable segments.
Solution Approach 2:
The patent applies local quality by assigning different optical properties (absorption, scattering, fluorescence) to different volumetric datasets within the same visualization. This enables specific regions or data types to be highlighted or suppressed locally through transfer function adjustments, improving clarity without losing underlying information.
2Manufacturing precision
If advanced rendering techniques (surface rendering, volume rendering) are used to visualize 3D data, then visualization quality is improved, but computational cost increases
Solution Approach 1:
The patent replaces complex geometric rendering mechanics (surface modeling, ray-tracing) with a volumetric transfer function approach. Instead of computing intermediate geometric representations, the system directly renders volumetric data by applying optical properties and transfer functions, significantly reducing computational overhead while maintaining visualization quality.
Solution Approach 2:
The patent changes the rendering parameters from geometric operations to optical property assignments. By defining absorption, scattering, and fluorescence coefficients for each volumetric dataset and using transfer functions to map data values to optical properties, the system achieves high-quality visualization with lower computational cost compared to traditional surface or volume rendering.
3Loss of information
If multiple volumetric datasets from different modalities are rendered simultaneously, then information completeness is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary action by pre-defining optical properties (absorption, scattering, fluorescence) and transfer functions for each volumetric dataset before rendering. This preparation allows multiple datasets to be rendered simultaneously with optimized performance, as the computational parameters are established in advance rather than calculated during the rendering process.
