Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging technologies face challenges in producing clear, three-dimensional images from volumetric data, as clinicians often find it overwhelming to integrate multiple two-dimensional data slices to visualize complex organs or tissues effectively, leading to a need for improved image processing methods that enhance clarity and understanding.
Innovation Solution
An improved multiple-dimensional imaging system comprising a memory-storage unit, an image processor, and an image-rendering device that converts three-dimensional data into a two-dimensional representation aligned with an operator-identified view axis, allowing for a composite view generation that includes information associated with a structure-of-interest, thereby enhancing image clarity and enabling real-time observation of tissue movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If volume rendering is used to display three-dimensional images, then comprehensive information about all data elements is contained, but image clarity and distinguishability of structures are reduced
Solution Approach 1:
The patent segments the volume rendering process into multiple components: extracting specific structures of interest from the volumetric data, rendering them separately with enhanced clarity, and combining them with background information. This allows different parts of the image to have different rendering qualities - detailed structures are clearly depicted while maintaining overall information completeness.
Solution Approach 2:
The patent applies local quality by selectively enhancing specific regions of interest within the volume rendering. Structures of interest are rendered with high detail and clarity, while other areas maintain appropriate level of detail. This localized enhancement resolves the contradiction by providing clear images where needed without sacrificing overall information completeness.
2Loss of information
If multiple two-dimensional data slices are integrated to visualize three-dimensional structures, then comprehensive anatomical information is obtained, but visual system strain increases
Solution Approach 1:
The patent transforms the viewing experience from multiple two-dimensional slices to a three-dimensional volume rendering that can be interactively viewed from any angle. This dimensional change allows the brain to process spatial relationships more efficiently, reducing the cognitive and visual strain associated with mentally reconstructing three-dimensional structures from multiple two-dimensional images while maintaining complete anatomical information.
3Measurement precision
If maximum-intensity projection is used to display volumetric data, then key structures are visible, but subtle details and tissue movement are lost
Solution Approach 1:
The patent incorporates dynamic elements by enabling real-time observation of tissue movement through the volume rendering. The system allows interactive manipulation and real-time display of moving structures, transforming static projections into dynamic visualizations that preserve tissue movement information while maintaining structure visibility through selective rendering of moving elements.

AI summary
An improved imaging system includes a memory-storage unit, a multiple-dimensional image processor configured to convert information within a multiple-dimensional data set to a two-dimensional representation in a plane orthogonal to an operator-identified view axis, and an image-rendering device configured to display the two-dimensional representation of a volume-of-interest contained within the three-dimensional data set, wherein the two-dimensional representation is responsive to pixel values associated with a faceplate orthogonal to the view axis. A method for viewing information includes identifying a view axis that intersects a multiple-dimensional data set, modifying the multiple-dimensional data set to align the multiple-dimension data set responsive to the view axis, locating a portion of a structure-of-interest along a vector parallel to view axis, associating a set of pixels with a faceplate, and generating a composite view in accordance with the faceplate.
