Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional two-dimensional medical imaging is used, then the system complexity is low, but the surgical planning precision and spatial understanding are insufficient
Solution Approach 1:
The patent transforms traditional two-dimensional medical images into three-dimensional stereoscopic visualizations, adding a spatial dimension to enhance surgical planning precision. The system renders 3D anatomical structures from 2D imaging data, allowing surgeons to view and manipulate anatomical models from multiple angles while maintaining accurate spatial relationships.
Solution Approach 2:
The patent introduces an immersive display system as an intermediary between the surgeon and medical imaging data. This intermediary component (VR/AR headset or immersive display) translates complex 3D medical data into intuitive visual representations, bridging the gap between raw imaging data and surgical decision-making without requiring complex manual manipulation of traditional 2D images.
2Ease of operation
If six degrees of freedom interaction is implemented, then the ease of operation for 3D manipulation is improved, but the device complexity increases
Solution Approach 1:
The patent employs a universal control interface that can detect and respond to multiple types of user inputs (hand gestures, controller movements, eye tracking) through a single system. This multi-functional input device can perform various manipulation tasks (rotation, zooming, panning, selection) without requiring separate specialized devices for each function, thereby improving ease of operation while limiting the increase in overall system complexity.
3Productivity
If real-time stereoscopic image rendering is performed, then the productivity for surgical planning is improved, but the use of energy and computational resources increases
Solution Approach 1:
The patent performs preliminary processing of medical imaging data to create optimized 3D models and pre-computes rendering parameters before the actual surgical planning session. By preparing anatomical models, segmentation data, and rendering configurations in advance, the system reduces real-time computational requirements, enabling faster and more energy-efficient stereoscopic image rendering during surgical planning.
Data Source
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.
