Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation image capturing apparatuses require lengthy setup processes for long-length image capturing, especially when changing image capturing positions or numbers of images, which increases the time and burden on both operators and subjects, particularly in capturing curved spinal or lower limb images.
Innovation Solution
A radiation image capturing apparatus with a control unit that maintains previous image capturing position data unless changes are detected, allowing for efficient long-length image capturing by omitting unnecessary settings and prompting necessary input operations through a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image capturing position data is reset for each long-length image capturing operation, then accurate positioning can be achieved, but the setting time and operational burden increase significantly
Solution Approach 1:
The control unit stores image capturing position data from previous operations and automatically retrieves it for subsequent operations. This preliminary action of storing and reusing position data eliminates the need for repeated manual setting, reducing setting time while maintaining positioning accuracy through automatic inheritance of valid position information
Solution Approach 2:
The system automatically manages image capturing position data by storing, retrieving, and applying position information without requiring manual intervention for each operation. The control unit serves itself by maintaining a memory of position data and autonomously selecting appropriate positions based on operation history, thereby reducing operational burden while ensuring accurate positioning
2Manufacturing precision
If image capturing conditions are customized for each specific examination type, then optimal imaging quality is achieved, but the complexity of operation increases
Solution Approach 1:
The control unit is designed to handle multiple types of long-length image capturing operations (spinal imaging, lower limb imaging, etc.) using a unified data management system. By creating a universal platform that stores and manages position data applicable across different examination types, the system maintains optimal imaging quality for each specific application while simplifying operation through consistent data inheritance mechanisms
Solution Approach 2:
The system dynamically adjusts image capturing parameters including position data based on the specific examination type while maintaining a standardized data structure. By allowing parameters like position, number of images, and capturing range to be automatically selected from stored data based on examination type, the system achieves optimal imaging quality for each application without increasing operational complexity
3Reliability
If the number of images to be captured is increased to ensure complete coverage, then diagnostic completeness improves, but the exposure dose and examination time increase
Solution Approach 1:
The system uses stored position data from previous operations as feedback to automatically determine the appropriate number of images and capturing range for subsequent operations. By analyzing historical data about subject anatomy and optimal coverage, the control unit can accurately calculate the minimum necessary number of images required for complete diagnostic coverage, thereby reducing unnecessary exposure while maintaining diagnostic completeness

AI summary
A radiation image capturing apparatus maintains previous image capturing position data stored in an image capturing position data storage unit 15 of a control unit 13 when a setting of a reference position of a long-length imaging region and the number of images to be captured are not changed. On the other hand, the radiation image capturing apparatus clears the previous image capturing position data stored in the image capturing position data storage unit 15 of the control unit 13 when either a setting of a reference position of a long-length imaging region or the number of images to be captured is changed. Then, the control unit 13 temporarily prohibits X-ray image capturing, and a warning display unit 16 causes a display unit 11 to display a display prompting input of image capturing position data for subsequent long-length image capturing. This display is kept displayed until an operator inputs image capturing position data for subsequent long-length image capturing. When an operator inputs image capturing position data for the subsequent long-length image capturing and the data is stored in the image capturing position data storage unit 15 of the control unit 13, the control unit 13 releases the prohibition of image capturing.
