Solution Overview

Problem

The large amount of original image data in medical imaging, particularly in multi-planar reformation (MPR) of oral cavity CT scans, leads to inefficiencies in data storage, transmission, and operation, resulting in low doctor observation efficiency and inconvenient operations.

Innovation Solution

A method involving image compression to generate a target file based on oral cavity three-dimensional model data, reducing data storage and transmission volume, and performing multi-planar reformation using this compressed data to improve efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If original image data is used for multi-planar reformation, then complete tissue and organ information is preserved, but data storage and transmission volume is large

Engineering Contradiction:
Improvetissue and organ informationVSAvoiddata storage and transmission volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary tissue and organ information from the original image data to create a simplified data structure. This allows complete preservation of diagnostically relevant information while removing redundant data, thereby reducing storage and transmission volume without losing essential medical information.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the image data by identifying and separating tissue and organ information from other elements. This segmentation enables selective retention of medically relevant data while discarding unnecessary information, achieving both information preservation and volume reduction simultaneously.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If original image data is used for multi-planar reformation, then complete diagnostic information is available, but data transmission efficiency is low

Engineering Contradiction:
Improvediagnostic informationVSAvoiddata transmission efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The patent extracts only the diagnostically essential information from the original image data, creating a compact representation that retains all necessary diagnostic details. This extracted data structure transmits much faster while preserving complete diagnostic capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the data representation parameters by transforming the original image data into a simplified structure that maintains diagnostic information. This parameter transformation reduces data size and improves transmission efficiency without compromising diagnostic quality.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If original image data is used for multi-planar reformation, then complete image quality is maintained, but operation convenience is poor

Engineering Contradiction:

Solution Approach 1:

The patent extracts the essential image quality characteristics while removing redundant data elements. This creates a streamlined data structure that maintains complete image quality for diagnostic purposes while significantly improving operational convenience through faster loading and manipulation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary processing to extract and organize only the necessary image data before the actual multi-planar reformation operation. This preliminary action prepares the data in an optimized format that maintains complete image quality while making subsequent operations more convenient and efficient.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If original image data is used for multi-planar reformation, then complete data fidelity is preserved, but MPR efficiency is low

Engineering Contradiction:
Improvedata fidelityVSAvoidMPR efficiency
Core Design Contradiction:

Solution Approach 1:

The patent extracts only the data elements essential for maintaining fidelity in multi-planar reformation operations. By removing redundant information while preserving all data needed for accurate MPR, the system achieves complete data fidelity with significantly improved processing efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the original image data into essential and non-essential components, retaining only those segments necessary for maintaining data fidelity during MPR. This segmentation approach preserves complete reliability while enabling faster processing and higher MPR efficiency.

Inventive Principle:
Principle #1Segmentation
