Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional two-dimensional medical imaging is used, then device complexity is reduced, but three-dimensional spatial relationships and surgical navigation precision are compromised
Solution Approach 1:
The patent transforms two-dimensional medical images into three-dimensional stereoscopic visualizations by adding a depth dimension. The system renders stereoscopic images from multi-planar reconstruction data, allowing surgeons to view anatomical structures in 3D space while maintaining the ability to manipulate and navigate through the volumetric data interactively.
2Adaptability or versatility
If fixed viewing angles are used in medical imaging, then device complexity is reduced, but adaptability to different surgical perspectives is limited
Solution Approach 1:
The patent implements dynamic viewing capabilities where the stereoscopic image can be rotated, tilted, and viewed from multiple angles during surgical navigation. The system allows real-time adjustment of viewing perspectives without requiring physical repositioning of imaging equipment, providing adaptability to different surgical approaches and anatomical orientations.
3Measurement precision
If detailed three-dimensional rendering is implemented, then surgical navigation precision is improved, but image processing time and computational complexity increase
Solution Approach 1:
The patent performs preliminary processing of medical imaging data to create pre-computed three-dimensional volumetric representations before surgery. These pre-rendered stereoscopic images and multi-planar reconstructions are prepared in advance, allowing detailed anatomical visualization during surgery without real-time processing delays, thus reducing intraoperative waiting time while maintaining high precision.

AI summary
A computer-implemented method for adjustable three-dimensional (3D) rendering of locations in a subject includes a step of receiving image data having a discrete spatial resolution for white matter tracts in a subject where the image data is generated by magnetic diffusion imaging. A first stereoscopic image is rendered on a display from the image data. The first stereoscopic image includes image parallax, which allows three-dimensional viewing. An input is received from a pointing device or a hand gesture that enables manipulation of the first stereoscopic image while maintaining proper three-dimensional spatial relationships. The pointing device interacts with the first stereoscopic image in three-dimensional space with six degrees of freedom.
