Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems face challenges in accurately identifying the positions of receptor fields during automatic exposure control when the imaging apparatus is detached from a stand, leading to potential failures in exposure control and inappropriate radiation image density.
Innovation Solution
The system includes a detector with a built-in automatic exposure control function and a mark for orientation identification, along with a control apparatus that displays icons on a display unit to help operators identify the correct receptor field positions, and allows for rotation adjustments based on acquired detector orientation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation imaging apparatus is detached from the stand to enable portable imaging, then the adaptability and versatility of the imaging system is improved, but the ease of operation deteriorates due to difficulty in identifying the positions of receptor fields
Solution Approach 1:
The patent applies visual display of icon orientations on the display unit to indicate receptor field positions. By changing the visual representation (icon orientation) based on detector orientation, the system provides intuitive visual feedback that helps operators easily identify receptor field positions during portable imaging, resolving the contradiction between portability and ease of operation
Solution Approach 2:
The patent creates a visual copy or representation of the detector's physical orientation through icons displayed on the display unit. This graphical representation mirrors the actual detector orientation, allowing operators to understand receptor field positions without physically referencing the detector, thus improving ease of operation while maintaining portable imaging capability
2Adaptability or versatility
If the radiation imaging apparatus is rotated with respect to the subject to achieve different imaging angles, then the adaptability of the imaging system is improved, but the measurement precision of receptor field positions deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the control apparatus continuously updates the icon orientation on the display unit based on the detector's current orientation. This real-time feedback allows operators to accurately understand receptor field positions regardless of detector rotation, maintaining measurement precision while enabling imaging angle flexibility
Solution Approach 2:
The patent makes the visual representation dynamic by automatically adjusting icon orientation to match detector orientation. This dynamic adaptation ensures that the displayed information always reflects the current physical state, allowing precise receptor field identification even when the detector is rotated to different angles
