Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation image photographing systems, patients and others in the vicinity are unaware when radiation emission has finished, leading to stress and safety concerns due to the invisible nature of radiation and the need for continuous monitoring.
Innovation Solution
A radiation image photographing system that includes a radiation generator on a round visit cart or transportable generator, equipped with a calculation device to determine the remaining time for radiation image sequencing and a display device to visually indicate this time to patients and others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If radiation is emitted multiple times to perform videography, then radiation images can be acquired in sequence, but patients and others cannot recognize when emission has finished leading to stress and safety concerns
Solution Approach 1:
The patent applies visual indication through color-coded display lights to show radiation emission status. The display device changes color or illumination state to clearly indicate when radiation is being emitted versus when it has finished, making the invisible radiation status visible to patients and others in the vicinity.
Solution Approach 2:
The patent introduces a display device as an intermediary between the radiation generator and humans. This mediator translates the invisible radiation emission status into visible visual information, allowing patients and others to understand the radiation emission state without being directly exposed to or monitoring the radiation itself.
2Manufacturing precision
If radiation emission time is extended for proper imaging, then image quality improves, but patient stress increases due to prolonged invisible exposure
Solution Approach 1:
The display device provides clear visual feedback about radiation emission status and duration, allowing patients to understand how long they need to remain still. This reduces anxiety about invisible prolonged exposure while maintaining the necessary emission time for proper image quality.
Solution Approach 2:
The system provides real-time visual feedback to patients about the radiation emission status. This feedback loop allows patients to understand the current state and expected duration, reducing stress while ensuring the complete emission cycle is completed for quality imaging.
3Manufacturing precision
If photographer continuously monitors patient posture during emission, then image quality is maintained, but photographer stress increases due to constant attention required
Solution Approach 1:
The display device serves as an intermediary that communicates radiation status to all parties, reducing the photographer's burden of continuous monitoring. The visual indication system handles the communication of emission status, allowing the photographer to focus on technical aspects while patients and others self-monitor through the display.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables patients and others to precisely recognize when radiation emission has ceased, reducing stress and ensuring safety by providing a visible indication of the remaining time, thus minimizing unnecessary restrictions and tensions.
Implementation Method 1
a radiation generator (57) installed on a round visit cart (50) or a transportable radiation generator (57*)
Implementation Method 2
a flat panel detector (FPD) cassette... radiation that has passed through an object is converted, by each radiation detecting element 7, into image data D in accordance with its intensity
