Solution Overview
Problem
Current X-ray sources for static CT systems face challenges in manufacturing large-diameter integral ring anodes and achieving sufficient X-ray strength with modularized focal points, leading to suboptimal scanning performance.
Innovation Solution
An arc-shaped multi-focal point fixed anode gate controlled X-ray source is designed with uniformly distributed focal points on a common distribution circle, utilizing an arc-shaped housing, ray tube bracket, and gate controlled switches to create a simple and cost-effective structure that can be assembled into an integral ring, allowing for controlled X-ray emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reflected raying is adopted with an integral ring of fixed anodes, then a full circle of ray sources can be formed, but the large diameter makes the anodes difficult to manufacture
Solution Approach 1:
The patent divides the integral ring anode into multiple separate fixed anode reflected ray tubes distributed along an arc-shaped housing. Each ray tube contains its own anode, eliminating the need to manufacture a single large-diameter integral ring anode. The ray tubes are positioned with their focal points on a distribution circle, achieving the full circle ray source capability through segmentation of the anode structure into manageable modular units.
2Ease of manufacture
If transmission type raying with modularized focal points is adopted, then manufacturing is simplified, but the ray strength becomes insufficient for practical detection
Solution Approach 1:
The patent employs fixed anode reflected ray tubes instead of transmission type ray tubes. The fixed anode design with reflective geometry provides superior X-ray generation capability compared to modularized transmission focal points. Each ray tube is equipped with a gate controlled switch for precise emission control, and the reflected anode geometry optimizes X-ray output strength to meet practical detection requirements while maintaining modular manufacturability.
3Adaptability or versatility
If multiple focal points are distributed circumferentially, then scanning coverage is improved, but the structure becomes more complex
Solution Approach 1:
The patent uses identical fixed anode reflected ray tube modules distributed along a common arc-shaped housing. Each module is a universal, standardized unit containing an anode, cathode, and gate controlled switch. This modular universality allows multiple focal points to be distributed circumferentially with their points on a distribution circle, achieving comprehensive scanning coverage while simplifying the overall structure through repetition of standardized components rather than custom-designed complex arrangements.
