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

VSEngineering 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

Engineering Contradiction:
Improvevisualization capabilityVSAvoidinvasiveness to patient
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #26Copying

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveflexibility and control in visualizingVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #23Feedback

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.
