X-ray Imaging Apparatus Automatic Person Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging apparatuses increase the burden on examiners by requiring them to manually check the examination room for individuals other than the subject before emitting X-rays, which can lead to unnecessary exposure if someone is present and difficult to confirm through windows.
Innovation Solution
An X-ray imaging apparatus with an X-ray source and detector in the examination room, an imaging unit, an operation unit outside, and a control unit that generates images and issues caution notifications when a person other than the subject is detected, allowing for alerting the examiner without direct room checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the examiner manually checks the examination room before emitting X-rays, then the safety of persons in the examination room is improved, but the burden and time required for the examiner increases
Solution Approach 1:
The system performs self-detection of persons in the examination room using the imaging unit and control unit, eliminating the need for manual checking by the examiner. The apparatus automatically monitors the room and issues notifications, allowing the examiner to focus on medical tasks without time-consuming safety checks.
Solution Approach 2:
The system provides real-time feedback to the examiner through notification units that alert when persons are detected in the examination room. This continuous feedback loop ensures safety while allowing the examiner to operate without constant manual verification, reducing time loss while maintaining reliability.
2Measurement precision
If the examiner enters the examination room to check for persons, then detection accuracy is improved, but the complexity of the operation and time burden increases
Solution Approach 1:
The mechanical action of the examiner physically entering and visually scanning the room is replaced by an automated imaging system with image processing capabilities. The imaging unit captures images and the control unit analyzes them to detect persons, providing accurate detection without requiring the examiner to leave the control room or perform manual checks.
Solution Approach 2:
The imaging unit and control unit serve as intermediaries between the examination room and the examiner. Instead of direct observation by the examiner, the system uses captured images as an intermediary to convey information about persons in the room, simplifying the examiner's task while maintaining detection accuracy.
3Ease of operation
If the examiner relies solely on window observation, then the ease of operation is improved, but the detection capability for persons in blind spots deteriorates
Solution Approach 1:
The system transitions from two-dimensional visual observation through a window to comprehensive multi-angle imaging coverage. The imaging unit is positioned to capture the entire examination room including areas not visible through the window, adding spatial dimensions to detection capability and eliminating blind spots while maintaining ease of operation.
Solution Approach 2:
The imaging unit serves multiple functions: it monitors areas visible through the window and simultaneously detects persons in previously invisible blind spots. This multi-functional capability ensures comprehensive detection coverage without requiring additional manual verification methods, maintaining operational convenience while improving detection precision.

Data Source
AI summary
An X-ray imaging apparatus includes an X-ray source, a detector for detecting X-rays, an imaging unit, an operation unit, a notification unit, and a control unit. The control unit generates an image of an inside of an examination room. Further, when detecting that a person other than a subject is present in the examination room based on the image of the inside of the examination room, the control unit performs control to issue caution information indicating that a person other than a subject is present in the examination room.
