Solution Overview
Problem
Conventional X-ray detector management systems face challenges in easily checking inspection results across multiple locations, leading to potential use of defective detectors and unnecessary exposure during imaging.
Innovation Solution
A management system that includes an inspection unit and a validity period setting unit, allowing for remote inspection of X-ray detectors and preventing imaging if inspection results are invalid, with self-diagnosis units for routine and start-operation inspections, and a network for sharing inspection data across inspection rooms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If X-ray detectors are shared between multiple inspection rooms, then resource utilization is improved, but inspection result verification becomes difficult requiring technicians to physically visit other rooms
Solution Approach 1:
The system creates a digital copy of inspection results from the source inspection room and transmits it to the destination inspection room via network communication. This allows technicians to verify inspection results locally without physically visiting the detector's storage location, resolving the contradiction between detector sharing and ease of verification.
2Productivity
If inspection results are not verified before imaging, then imaging workflow is faster, but defective detectors may be used causing unnecessary exposure and poor image quality
Solution Approach 1:
The system performs inspection result verification as a preliminary action before allowing X-ray imaging to proceed. The determination unit checks validity flags and transmission timestamps to ensure detector quality is confirmed, preventing defective detectors from being used while maintaining workflow efficiency through automated validation.
Solution Approach 2:
The system implements a feedback mechanism where inspection results are transmitted back to the imaging location, and the determination unit uses this feedback to control whether imaging can proceed. The validity flag and timestamp provide continuous feedback on detector status, ensuring quality assurance without manual intervention.
3Reliability
If comprehensive inspection items are checked, then detector reliability is improved, but inspection time and complexity increase
Solution Approach 1:
The X-ray detector performs self-diagnosis by executing inspection routines internally and generating inspection results autonomously. The self-diagnosis unit checks multiple parameters including battery voltage, operating temperature, and detector performance, then transmits results to the management system. This self-service approach ensures comprehensive inspection without requiring external intervention for each check, maintaining reliability while reducing inspection time.

AI summary
The management system of the X-ray detectors according to the embodiments detects X-rays irradiated from the X-ray generator when X-ray imaging is carried out, and includes an inspection unit and a validity period setting unit. The inspection unit inspects at least one of performance, function, and operation of an actual operation state of the X-ray detector. The validity period setting unit sets a validity period which is a criterion for determining whether the inspection results inspected are valid or not. The system is configured that the X-ray imaging is not performed on a subject when the inspection results are determined to be invalid based on the validity period.
