Synchronized 3D Model Clipping for Surgical Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical procedures lack efficient methods for detailed pre-surgery planning, as 3D CT and MRI images provide limited benefits when used alone, and existing techniques for studying patient-specific anatomy can be invasive.
Innovation Solution
A synchronized 3D model clipping system that allows for dynamic clipping of a 3D model of patient anatomy along a vector, with parameters automatically regenerated to reflect movement within a frame of reference, enabling enhanced visualization and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If 3D CT and MRI images are used for pre-surgery planning, then visualization capability is improved, but the benefit is limited and existing techniques may be invasive to the patient
Solution Approach 1:
The patent creates a virtual 3D model that is a digital copy of the patient's anatomy from CT/MRI scans, allowing detailed pre-surgery planning and rehearsal without any additional invasive procedures. The virtual model replicates the anatomical structures enabling comprehensive study before surgery.
Solution Approach 2:
The patent segments the 3D model into different anatomical structures and allows selective clipping and visualization of specific regions. This enables focused examination of particular areas of interest while maintaining the ability to reveal or hide different anatomical layers and structures.
2Adaptability or versatility
If dynamic clipping parameters are automatically regenerated to reflect movement, then flexibility and control in visualizing 3D models is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic clipping where the clipping parameters are automatically regenerated in sync with user movement within the frame of reference. The clipping plane and parameters adjust in real-time as the user moves, providing adaptive visualization that responds to user actions without requiring manual reconfiguration.
Solution Approach 2:
The system provides feedback by automatically regenerating clipping parameters based on detected user movement. The system monitors user position and movement within the frame of reference, then adjusts the clipping parameters accordingly, creating a closed-loop system that adapts to user actions.
Data Source
AI summary
A method, including the steps of a modeling computer: receiving data indicative of a frame of reference with respect to a vector; generating data indicative of first parameters, based on the frame of reference, for clipping a 3D model of a patient anatomy along the vector; clipping the 3D model based on the first parameters, thereby generating a first clipped portion; communicating the first clipped portion to a display; receiving data indicative of movement within the frame of reference; automatically regenerating second parameters, based on and in sync with the data indicative of the movement, for clipping the 3D model; clipping the 3D model based on the second parameters, thereby generating a second clipped portion; and communicating the second clipped portion to the display.
