Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dynamic radiographing systems set a constant target image quality regardless of the presence or absence of dynamic analysis, leading to issues such as low image quality and high patient dose during certain dynamic analysis items.
Innovation Solution
A radiographing control apparatus that determines first and second radiographing conditions based on information about the presence or absence of dynamic analysis and the specific dynamic analysis item, thereby adjusting the target image quality and optimizing the radiographing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a constant target image quality is set for all dynamic radiographing cases, then the device operation is simplified, but the image quality becomes insufficient for certain dynamic analysis items and the patient dose becomes unnecessarily high
Solution Approach 1:
The patent applies dynamics by making the target image quality adjustable based on the type of dynamic analysis being performed. The system transitions from a fixed constant quality setting to a dynamic quality setting that adapts to different analysis requirements (e.g., motion analysis vs. positional analysis), thereby optimizing both image quality and patient dose for each specific application
Solution Approach 2:
The patent changes the parameter of target image quality from a constant value to a variable value that depends on the dynamic analysis type. By linking the quality parameter to the analysis item selection, the system can optimize radiographing conditions to achieve sufficient image quality for each analysis purpose while minimizing unnecessary radiation exposure
2Manufacturing precision
If a high target image quality is set to ensure sufficient image quality for all analysis items, then the image quality is sufficient, but the patient dose becomes unnecessarily high
Solution Approach 1:
The patent optimizes the target image quality parameter by setting it according to the specific dynamic analysis item. For analysis items requiring high quality (e.g., positional analysis), higher quality settings are applied, while for items tolerating lower quality (e.g., motion analysis), lower quality settings are used, thereby reducing patient dose while maintaining sufficient image quality
Solution Approach 2:
The patent applies partial action by setting the target image quality to the minimum necessary level for each specific analysis item rather than using a uniformly high quality setting for all cases. This ensures sufficient image quality for the intended analysis while avoiding excessive radiation exposure
3Object-affected harmful factors
If a low target image quality is set to reduce patient dose, then the patient dose is reduced, but the image quality becomes insufficient for certain dynamic analysis items
Solution Approach 1:
The patent adjusts the target image quality parameter dynamically based on the analysis item selection. The system ensures that for each analysis type, the quality parameter is set to an appropriate level that provides sufficient image quality for that specific analysis while minimizing patient dose, rather than using a uniformly low quality setting
4Manufacturing precision
If radiographing conditions are optimized for specific dynamic analysis items, then the image quality and dose are optimized, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by creating a unified control system that handles multiple dynamic analysis items through a single mechanism. The radiographing control apparatus integrates the functionality to select analysis items, determine appropriate target image qualities, and optimize radiographing conditions within one system, avoiding the need for separate specialized systems for each analysis type

AI summary
A radiographing control apparatus emits radiation to an object and obtains a plurality of frame images to control dynamic radiographing that radiographs dynamics of the object. The radiographing control apparatus includes a hardware processor. The hardware processor obtains first order information that includes at least one of information on presence or absence of dynamic analysis executed for a dynamic image obtained by the dynamic radiographing, and information on a dynamic analysis item, determines a first radiographing condition and a target image quality, based on the obtained first order information, and determines a second radiographing condition for achieving the determined target image quality.
