Mobile X-Ray Detector With Integrated AEC Chamber Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional x-ray systems with automatic exposure control (AEC) components are limited to fixed locations, preventing their use in mobile applications where a single detector is moved between multiple locations, necessitating duplicate AEC chambers and grids at each location.
Innovation Solution
Integration of AEC sensors and chambers within a mobile detector, eliminating the need for separate AEC chambers and grids by incorporating them into the detector's housing, which includes a shield and circuitry to reduce noise and mechanical stress, allowing AEC functionality across various locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AEC components are mounted in a fixed location, then AEC functionality is provided at that location, but the system cannot be used in mobile applications and requires duplicate components at each location
Solution Approach 1:
The patent combines the AEC chamber and AEC sensors directly into the detector housing, merging previously separate components (detector and AEC system) into a single integrated unit. This eliminates the need for separate AEC chambers at multiple locations and enables mobile applications while reducing overall system complexity.
Solution Approach 2:
The integrated detector with built-in AEC functionality serves multiple purposes: it acts as both the imaging detector and the automatic exposure control system. This multi-functional design allows the same device to be used across different locations without requiring location-specific AEC installations.
2Reliability
If separate AEC chambers are installed at each location, then AEC functionality is available at each location, but costs and system complexity increase
Solution Approach 1:
By merging the AEC chamber and sensors into the detector housing, the system eliminates the need to manufacture and install separate AEC chambers at each location. This single integration reduces manufacturing costs while maintaining AEC availability through the portable detector.
3Measurement precision
If AEC sensors are separate from the detector, then AEC measurement is possible, but the system requires fixed installation and cannot be moved between locations
Solution Approach 1:
The patent integrates AEC sensors directly into the detector housing, combining the measurement function with the detector. This integration maintains exposure control accuracy while enabling the entire system to be moved between locations, providing both precision and flexibility.
