Solution Overview
Problem
Existing medical-use image processing techniques fail to provide satisfactory verification of the spatial position of arbitrary cross sections in three-dimensional medical image data, limiting accurate diagnosis.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only the intended cross section and rough position in three-dimensional space are referenced, then the device complexity is reduced, but the measurement precision of spatial position verification deteriorates
Solution Approach 1:
The patent divides the verification task into multiple independent components: basic cross-sectional image, auxiliary cross-sectional images from different orientations (sagittal, coronal, axial), and positional relationship information. Each component serves a specific verification function, allowing precise spatial position confirmation without requiring a completely complex integrated system.
Solution Approach 2:
The patent introduces auxiliary cross-sectional images as intermediary elements that mediate between the basic cross-sectional image and the three-dimensional spatial position. These auxiliary images from different orientations serve as reference markers that facilitate accurate verification of the basic cross-section's spatial location without directly displaying the entire three-dimensional space.
2Measurement precision
If auxiliary cross sections and positional relationship information are added, then the measurement precision of spatial position verification is improved, but the device complexity increases
Solution Approach 1:
The patent makes the image processing apparatus multi-functional by enabling it to generate not only the basic cross-sectional image but also auxiliary cross-sectional images from multiple orientations (sagittal, coronal, axial) and positional relationship information. This universal capability allows a single apparatus to perform comprehensive spatial verification without requiring multiple separate devices.
Solution Approach 2:
The patent transitions from two-dimensional basic cross-sectional images to three-dimensional spatial verification by adding auxiliary cross-sectional images from different orientations (sagittal, coronal, axial planes). This dimensional expansion enables precise spatial position verification by viewing the same anatomical structure from multiple spatial dimensions simultaneously.
3Ease of operation
If multiple cross-sectional images and positional information are displayed, then the ease of operation for verifying spatial position is improved, but the loss of information increases
Solution Approach 1:
The patent applies local quality by displaying different types of information (basic cross-sectional image, auxiliary cross-sectional images, positional relationship information) in distinct, organized regions of the display. Each region serves a specific verification function, allowing users to process information locally without being overwhelmed by a uniform display of all data simultaneously.
Solution Approach 2:
The patent segments the displayed information into distinct components: basic cross-sectional image area, auxiliary cross-sectional image areas from different orientations, and positional relationship information areas. This segmentation organizes the potentially overwhelming information into manageable, functionally distinct sections that can be processed systematically by the user.
