Solution Overview

Problem

Current visualization methods for coronary circulation simulations cannot accurately display microcirculatory systems in three-dimensional structures, as they are defined only in two-dimensional flat structures, leading to an inability to observe simulation results on a three-dimensional model.

Innovation Solution

A visualization apparatus that transforms a two-dimensional vascular network model into a three-dimensional structure by locating blood vessels on a cylindrical surface, allowing for the display of simulation results on a three-dimensional model, enabling easier observation of blood flow and physical quantity distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a two-dimensional flat structure is used to define the vascular network of the microcirculatory system, then the processing load of the computer is reduced and simulation can be performed efficiently, but the simulation result cannot be observed on a three-dimensional structure

Engineering Contradiction:
Improvesimulation processing efficiencyVSAvoidobservability of simulation result
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent transforms the two-dimensional vascular network model into a three-dimensional structure by mapping blood vessels onto a cylindrical surface. This dimensionality change allows the simulation results to be visualized in three dimensions while maintaining the computational efficiency of the original two-dimensional model, as the transformation is performed only for visualization purposes rather than simulation computation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a three-dimensional model of the microcirculatory system is created, then the simulation result can be observed on a three-dimensional structure, but the processing load of the computer becomes very large

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent creates a three-dimensional visualization structure by mapping the two-dimensional vascular network onto a cylinder, enabling three-dimensional observation without creating a full three-dimensional model of the microcirculatory system. This approach maintains computational efficiency while achieving the desired three-dimensional visualization.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent creates a visual representation copy of the vascular network on a cylindrical surface rather than modeling the actual three-dimensional microcirculatory system. This copy serves the purpose of visualization while avoiding the computational burden of a complete three-dimensional model.

Inventive Principle:
Principle #26Copying

3Device complexity

If the vascular network is defined on a two-dimensional plane, then the model structure is simple and processing is efficient, but the three-dimensional structure of the microcirculatory system is not reproduced

Solution Approach 1:

The patent maps the two-dimensional vascular network onto a three-dimensional cylindrical surface, adding spatial dimensionality to the visualization. This transformation preserves the simplicity of the two-dimensional model structure while reproducing the three-dimensional anatomical arrangement of blood vessels in the microcirculatory system.

AI summary

A visualization apparatus includes a memory unit and a computing unit. The memory unit stores a circulation model in which a vascular network, of an organ, having a diameter equal to or smaller than a predetermined value is defined on a two-dimensional plane, and a simulation result of a blood flow in the vascular network of the circulation model. The computing unit transforms the circulation model into a three-dimensional structure including the vascular network located on a cylindrical surface of a cylinder, and displays the simulation result on the three-dimensional structure.
