Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current X-ray imaging apparatuses lack the ability to intuitively provide users with information about the actual dose of X-rays, including the filter effect, making it difficult for users to select proper X-ray irradiation conditions that minimize radiation exposure while maintaining image quality.
Innovation Solution
An X-ray imaging apparatus and control method that includes an X-ray source, a display, and a controller to provide users with a graphic user interface for selecting X-ray irradiation conditions, calculating and displaying the actual dose of radiation, including the filter's influence, by storing relationships between dose and tube current, and adjusting parameters based on filter usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filter is used to reduce radiation dose, then radiation exposure is reduced, but user cannot intuitively recognize actual dose
Solution Approach 1:
The controller acts as an intermediary that calculates the actual radiation dose by considering filter attenuation effects, then presents this processed information to the user through the display. The display serves as a visual intermediary, converting complex dose calculations into intuitive graphical representations that users can easily understand.
Solution Approach 2:
The system changes the parameter representation from standard tube current (mAs) to an equivalent tube current that reflects the actual dose after filter attenuation. This parameter transformation allows users to intuitively compare different imaging conditions while accounting for filter effects.
2Device complexity
If filter attenuation is not considered in dose calculation, then calculation is simpler, but dose information is inaccurate
Solution Approach 1:
The system performs preliminary calculations of filter attenuation effects and stores correction values in advance. When a user selects imaging conditions, the controller retrieves pre-calculated correction values based on the selected filter and tube voltage, avoiding complex real-time calculations while ensuring accurate dose representation.
3Ease of operation
If detailed dose information is provided, then user can select proper dose, but information presentation becomes complex
Solution Approach 1:
The display uses color-coded visual representations to indicate different dose levels and filter effects. This allows users to quickly grasp dose information without interpreting complex numerical data, maintaining ease of operation while providing comprehensive dose details.
Solution Approach 2:
The system presents dose information in multiple dimensions - showing both the equivalent tube current and the actual dose values, allowing users to view the same information from different perspectives to facilitate informed decision-making without overwhelming complexity.
