Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cassette imaging, achieving an appropriate positional relationship between the patient, tube, and imaging device is challenging, leading to potential imaging failures and the need for re-imaging due to manual adjustments, as conventional systems lack the ability to confirm if the distance and angle between the tube and imaging device are correctly set.
Innovation Solution
A radiographic imaging support apparatus and method that utilizes a hardware processor to obtain an optical image of a portable imaging device and subject, determine an imaging range based on examination information, and display alignment information to ensure the imaging device is positioned correctly relative to the radiation source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging device is not fixed to the imaging stand (cassette imaging), then flexibility and adaptability are improved, but the difficulty of detecting and measuring the positional relationship worsens
Solution Approach 1:
The system captures optical images of the imaging device and subject, calculates their positional relationships, and provides feedback through displayed images and numerical values. This allows operators to see the actual positional relationship and make adjustments until the relationship meets requirements, resolving the difficulty of detecting and measuring position in flexible cassette imaging.
Solution Approach 2:
The system introduces an intermediary computational process that uses optical image recognition to detect the positions of the imaging device and subject, then calculates and displays the positional relationship. This intermediary mechanism bridges the gap between flexible positioning and accurate measurement.
2Adaptability or versatility
If manual adjustment of the positional relationship is required, then adaptability is improved, but the loss of time increases
Solution Approach 1:
The system provides real-time feedback by displaying the current positional relationship and comparing it with the required relationship. This allows operators to make informed adjustments more quickly, reducing the time lost to trial-and-error positioning while maintaining manual adaptability.
Solution Approach 2:
The system calculates and displays the required positional relationship in advance based on examination information, allowing operators to know the target position before making adjustments, thereby reducing adjustment time while maintaining flexibility.
3Device complexity
If conventional display technology is used, then device complexity is reduced, but the loss of information occurs
Solution Approach 1:
The system transitions from displaying only numerical values to displaying visual images showing the positional relationship. This dimensional change from 1D numerical data to 2D visual representation provides comprehensive information about both distance and angle appropriateness without significantly increasing device complexity.
