Solution Overview
Problem
Current stereoscopic biopsy devices face challenges in accurately targeting lesions, particularly in breast radiology, due to difficulties in distinguishing calcified portions in two-dimensional images, leading to prolonged procedures and decreased diagnostic efficiency.
Innovation Solution
A radiological image radiographing and displaying method and system that acquires images from different directions, displays stereoscopic images, and overlays position information as marks on two-dimensional images, allowing for precise targeting by designating positions in both stereoscopic and two-dimensional views, with optional features like abnormal shadow detection and biopsy needle path control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional images are displayed for targeting lesions, then the device complexity is reduced, but the measurement precision of lesion position deteriorates
Solution Approach 1:
The patent displays multiple two-dimensional radiological images from different radiographing directions simultaneously, enabling operators to identify the same lesion across different views. This multi-dimensional display approach maintains relative simplicity while improving positioning accuracy by allowing correlation of lesion positions across multiple planes.
2Device complexity
If manual targeting is performed in two-dimensional images, then the device complexity is reduced, but the productivity of biopsy procedure deteriorates
Solution Approach 1:
The system provides visual feedback by displaying marks at designated positions in two-dimensional images and showing corresponding three-dimensional position coordinates. This feedback mechanism allows operators to verify targeting accuracy and make rapid adjustments, improving procedure efficiency without requiring complex automated targeting systems.
3Measurement precision
If multiple radiological images are displayed to identify corresponding lesions, then the measurement precision of lesion identification is improved, but the loss of time in procedure increases
Solution Approach 1:
The patent merges multiple two-dimensional radiological images from different directions into a single display interface, allowing operators to view and correlate multiple views simultaneously. This combined display eliminates the need to switch between separate images, reducing procedure time while maintaining accurate lesion identification across multiple views.

AI summary
Targeting of a lesion which is performed by a stereoscopic biopsy device or the like is performed simply and highly accurately. Designation of a predetermined position in the stereoscopic image is received to acquire position information when a stereoscopic image is displayed, radiological images of radiographing directions are displayed as two-dimensional images, a mark based on the position information, which is designated in the stereoscopic image, is displayed in the two-dimensional images, designation of a predetermined position in the two-dimensional images is further received to acquire the position information after the mark is displayed.
