Digital Radiography Detector Selection via Radiation Dose Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Digital Radiography (DR) systems face inefficiencies and increased manufacturing costs due to the need to select and match X-ray detectors with specific positions, often requiring physical labels, which complicates imaging processes and can result in unnecessary radiation exposure.
Innovation Solution
A method is implemented in the DR system where dose sensors detect radiation doses from multiple imaging detectors, directing only the necessary detectors to receive radiation for image generation, and using reference data to select the best image when multiple detectors are needed, eliminating the need for physical labels and improving system reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical labels are used to identify X-ray detector positions, then detector selection can be achieved, but manufacturing costs increase and system complexity increases
Solution Approach 1:
The patent replaces the mechanical/physical label-based detection system with an electronic image recognition system. The computing device captures images of the detectors and uses image processing to identify detector positions and selections, eliminating the need for physical labels and their associated mechanical reading mechanisms.
Solution Approach 2:
The patent creates a digital copy (image) of the physical detector setup and processes this copy to extract information about detector positions and selections. This allows the system to identify detectors through image analysis rather than through physical label reading, reducing system complexity.

3Adaptability or versatility
If multiple X-ray detectors are available for different positions, then imaging versatility is improved, but imaging efficiency decreases due to the need to select the correct detector
Solution Approach 1:
The patent implements a feedback mechanism where the system automatically detects which detector is positioned where through image recognition, and uses this information to control the imaging process. The computing device receives image data, identifies detector positions, and automatically directs the imaging process to the correct detector, eliminating manual selection delays.
Solution Approach 2:
The system performs self-identification of detector positions and self-direction of the imaging process. The computing device automatically captures images, processes them to identify detector locations, and autonomously directs the imaging process without requiring operator intervention to select the correct detector.
4Productivity
If the DR system automatically directs detectors based on radiation dose detection, then imaging efficiency is improved, but unnecessary radiation exposure may occur
Solution Approach 1:
The patent performs preliminary detection of radiation doses by dose sensors before directing the imaging process. The system measures the radiation dose at each detector position in advance, identifies which detectors are receiving adequate radiation, and then directs the imaging process only to those detectors, preventing unnecessary radiation exposure to areas that won't contribute to the image.
