Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray image obtaining methods using polychromatic X-rays result in decreased image contrast, leading to poor quality images, especially when attempting to capture images with multiple energy levels.
Innovation Solution
The use of a scintillator panel divided into pixel blocks with scintillator layers having differing layer characteristics, such as varying thickness and material types, to generate multiple X-ray images based on different energy levels, allowing for increased contrast by optimizing the scintillator layer characteristics for each X-ray energy level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If polychromatic X-rays are used to obtain X-ray images, then the imaging process can be performed with a single radiation source, but the image contrast decreases and image quality deteriorates
Solution Approach 1:
The scintillator panel is divided into multiple scintillator layers, each optimized for specific X-ray energy levels. This segmentation allows different energy components of polychromatic X-rays to be detected separately, maintaining imaging speed while improving contrast through energy-specific detection.
Solution Approach 2:
Each scintillator layer is designed with specific material composition and thickness optimized for particular X-ray energy ranges. This local optimization ensures that each layer efficiently detects its target energy range, resolving the contradiction between using polychromatic X-rays for speed and maintaining contrast.
2Measurement precision
If scintillator layers with different characteristics are used for different energy levels, then image contrast improves, but device complexity increases
Solution Approach 1:
The scintillator panel is segmented into multiple layers with different characteristics, allowing each layer to be optimized for specific energy levels. This segmentation achieves improved contrast while managing complexity through modular layer design.
Solution Approach 2:
The scintillator layers vary in material composition and thickness parameters to optimize detection for different X-ray energy levels. By changing these parameters across layers, the system achieves high contrast without requiring fundamentally different detection mechanisms.
