Diagnostic Image Visualization Using Anatomical Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for visualizing three-dimensional anatomical objects in diagnostic imaging, such as the heart, suffer from inaccuracies and lack of reproducibility due to poorly defined geometric superposition of two-dimensional and three-dimensional views, leading to undesirable three-dimensional representations in medical diagnostics.
Innovation Solution
A method that records and processes multiple diagnostic image data records to create a precisely defined, two-dimensional representation by identifying anatomical features and projecting them onto a common display plane using an imaging specification adapted to the anatomy, eliminating the need for a three-dimensional view and ensuring standardized and reproducible visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional views are generated using rendering algorithms, then visualization of anatomical features is achieved, but geometric precision and reproducibility deteriorate
Solution Approach 1:
The patent extracts and eliminates the three-dimensional rendering step from the visualization process. Instead of generating 3D views through complex rendering algorithms, the method directly projects 3D image data onto 2D display planes using defined projection geometries, thereby removing the source of geometric imprecision while maintaining visualization capability
Solution Approach 2:
The patent inverts the conventional approach by not creating 3D views from 3D data, but rather by directly mapping 3D image data onto 2D display planes using projection transformations. This inversion eliminates the rendering complexity while achieving the desired visualization with improved geometric precision
2Reliability
If three-dimensional representations are used to visualize anatomical objects, then morphological information is displayed, but diagnostic reliability deteriorates due to geometric inaccuracies
Solution Approach 1:
The patent replaces the complex 3D rendering mechanism with a mathematical projection transformation system. By substituting the rendering algorithm with defined projection geometries and transformation matrices, the method achieves more reliable and accurate anatomical representation that can be consistently reproduced
Solution Approach 2:
The patent changes the fundamental parameters of the visualization approach by defining specific projection geometries and transformation parameters instead of relying on rendering algorithm parameters. This parameter change enables precise control over the projection process and ensures geometric accuracy in the 2D representations
3Adaptability or versatility
If multiple diagnostic image data records are combined in three-dimensional views, then comprehensive anatomical information is achieved, but standardization and reproducibility worsen
Solution Approach 1:
The patent creates a universal projection framework that can handle multiple types of diagnostic image data records (CT, MR, etc.) through a common mathematical transformation approach. This universal method ensures that regardless of the input data type, the projection process remains standardized and reproducible
Solution Approach 2:
The patent establishes fixed transformation parameters and projection geometries that remain consistent across different datasets. By defining these parameters upfront and maintaining them throughout the process, the method ensures high reproducibility when combining multiple diagnostic image data records
Data Source
AI summary
In a computer-assisted visualization of a three-dimensional anatomical object, two or more diagnostic image data records (1, 3, 4, 5) of the object are recorded. Thereafter, an imaging specification is defined for imaging the image data (1, 3, 4, 5) onto a two-dimensional display plane (8). In order to define the imaging specification, anatomical features (2) of the object are identified in at least one of the image data records (1). Finally, a combined two-dimensional representation is calculated by imaging the two or more image data records (1, 3, 4, 5) according to the previously defined imaging specification onto a common display plane (8).
