X-ray Irradiation Region Control via Camera and Touchscreen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray devices face challenges in accurately controlling the X-ray irradiation region due to abnormal placement of visible light sources and reflectors, leading to unnecessary exposure and wider imaging areas, which complicates precise radiography and increases patient exposure to unnecessary X-rays.
Innovation Solution
An X-ray device equipped with a camera and touchscreen display member that allows users to control the X-ray irradiation region through intuitive touch gestures, enabling precise selection and adjustment of the irradiation area, and providing real-time feedback on the amount of X-rays irradiated, using a combination of camera imaging, touchscreen interface, and input devices like remote controllers or motion recognition units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a visible light source and reflector are used to indicate the X-ray irradiation region, then the user can observe the irradiation region, but the structure becomes abnormally disposed and visible light is irradiated to a region different from the X-ray irradiation region
Solution Approach 1:
The patent uses a camera to capture an image of the object and displays it on a touchscreen, creating a visual copy of the irradiation region. This eliminates the need for physical visible light sources and reflectors, as the digital image accurately represents the X-ray irradiation area without requiring complex optical components.
Solution Approach 2:
The patent replaces the mechanical/optical system of visible light sources and reflectors with an electronic imaging system. The camera and touchscreen display substitute for the physical light indication mechanism, eliminating structural complexity while maintaining accurate irradiation region visualization.
2Loss of time
If imaging is performed in a wider region to avoid re-imaging, then re-imaging is avoided, but patients are exposed to unnecessary X-rays
Solution Approach 1:
The patent implements feedback by displaying the captured image on a touchscreen and allowing users to adjust the irradiation region based on visual feedback. Users can see the current irradiation area, make precise adjustments, and verify the changes before final imaging, eliminating the need for wider initial imaging and subsequent re-imaging.
Solution Approach 2:
The patent makes the irradiation region dynamic and adjustable. Instead of using a fixed wide region, the system allows real-time modification of the irradiation boundaries based on user input and visual feedback from the camera image, enabling precise control while minimizing unnecessary exposure.
3Illumination intensity
If the X-ray irradiation region controller uses a complex structure with visible light sources and reflectors, then the irradiation region can be observed, but the placement becomes abnormal and imaging accuracy decreases
Solution Approach 1:
The patent creates a digital copy of the irradiation region through camera imaging and displays it on a touchscreen. This visual copy provides clear visibility of the irradiation area without requiring physical light sources, and the digital representation maintains precise spatial correspondence with the actual X-ray irradiation region.
Solution Approach 2:
The patent replaces the mechanical light indication system with an electronic imaging and display system. The camera and touchscreen substitute for visible light sources and reflectors, providing superior visibility and precision while eliminating the structural complexity and misalignment issues of the mechanical system.
