3D Medical View Re-centering via Intermediate Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional visualization tools for medical vessel analysis are difficult to manipulate, as direct transitions between different views based on varying view parameters can be confusing and disorienting for users, making it hard to understand the interaction between object and view parameters.
Innovation Solution
A system that allows for sequential visualization of intermediate views between initial and final view parameter values, enabling users to smoothly transition between views by updating object and view parameters based on user input, using techniques like key frame interpolation to maintain a smooth animation and keep the object visible within the view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct transition between views based on varying view parameters is used, then view updating speed is improved, but user understanding and manipulation difficulty increases
Solution Approach 1:
The patent introduces intermediate views as a mediator between the initial and final views. When the alignment object moves to a new position, instead of directly jumping to the final view, the system generates and displays a sequence of intermediate views that gradually transition from the initial to the final view parameter values. This intermediary approach maintains fast view updating while improving user understanding by showing the transformation process step-by-step.
Solution Approach 2:
The system performs preliminary action by pre-calculating and preparing the sequence of intermediate view parameter values before displaying the transition. The intermediate views are computed in advance based on the initial and final view parameters, allowing the system to smoothly guide the user through the view transformation without real-time calculation delays, thus maintaining speed while improving comprehension.
2Loss of information
If sequential visualization of intermediate views is implemented, then user understanding is improved, but visualization time increases
Solution Approach 1:
The patent applies periodic action by displaying intermediate views in a systematic sequence at controlled intervals. The system generates multiple intermediate views with gradually changing parameter values and displays them in a predetermined sequence, allowing users to understand the transformation process while maintaining efficient visualization through structured, periodic presentation rather than continuous or random updates.
Solution Approach 2:
The system utilizes parameter changes by systematically varying the view parameters across the sequence of intermediate views. Each intermediate view has parameters that are progressively adjusted from the initial to the final values, creating a smooth transition that enhances user understanding. The parameter changes are calculated efficiently to minimize visualization time while maintaining clarity.
