Digital Radiographic Detector Self-Calibration Workflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging systems face inconsistencies in exposure techniques and calibration across multiple systems, leading to increased imaging workflow time and the need for frequent recalibration, especially when detectors are moved between rooms or systems.
Innovation Solution
Implementing a digital radiographic detector with integrated calibration data storage and processing capabilities, allowing for automatic calibration corrections, image processing, and synchronization of technique information, enabling detectors to operate independently and maintain consistent image quality across different systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If calibration data is stored externally and transferred between systems, then system complexity is reduced, but imaging workflow time increases and recalibration frequency increases
Solution Approach 1:
The patent combines calibration data storage and processing capabilities directly into the portable detector unit. The detector includes an integrated processor and memory system that stores calibration data locally, eliminating the need for external calibration management systems. This merging of functions allows the detector to perform self-calibration and maintain consistent image quality across multiple imaging systems without requiring data transfer or external processing.
2Device complexity
If calibration data is stored externally, then detector design is simplified, but recalibration frequency increases when moving between systems
Solution Approach 1:
The portable detector is designed with self-service calibration capabilities. The detector's integrated processor automatically retrieves calibration data from its own internal memory and applies it during image processing operations. This self-service approach ensures that calibration consistency is maintained regardless of which imaging system the detector is connected to, eliminating the need for frequent recalibration when moving between systems.
3Device complexity
If image processing is performed externally at the imaging system, then detector functionality is simplified, but workflow time increases
Solution Approach 1:
The patent merges image processing functionality directly into the portable detector unit. The detector includes an integrated processor that performs image processing operations using stored calibration data, eliminating the need for external processing at the imaging system. This integration allows presentation-ready images to be generated directly at the detector, reducing workflow time and improving productivity while maintaining consistent image quality across different imaging systems.
