Radiography Control with Timed Data for Scattered Radiation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiography control apparatuses face issues with inaccurate scattered radiation correction and delayed image processing due to changes in irradiation conditions and variable times for receiving irradiation information, leading to operator inconvenience and prolonged image display times.
Innovation Solution
A radiography control apparatus that obtains irradiation information before a specific timing to perform image processing using either the received information or stored fixed information, ensuring timely and accurate scattered radiation correction without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radiography control apparatus waits to receive irradiation information from the irradiation apparatus before performing scattered radiation correction, then the accuracy of scattered radiation correction is improved, but the time required to display the image is increased
Solution Approach 1:
The radiography control apparatus performs scattered radiation correction using fixed irradiation information stored in advance, before receiving the actual irradiation information from the irradiation apparatus. This preliminary correction allows the image to be displayed without delay, while the accuracy is subsequently improved when the actual irradiation information is received and processing is repeated if necessary.
2Productivity
If fixed information is used for scattered radiation correction, then the image processing speed is improved, but the accuracy of correction deteriorates when irradiation conditions change
Solution Approach 1:
The system dynamically adjusts the scattered radiation correction process in two stages: first using fixed information for rapid processing, then potentially repeating the process with actual irradiation information when received. This dynamic approach balances processing speed with accuracy based on the availability of real-time data.
Solution Approach 2:
The system changes the parameter source from fixed stored information to actual real-time irradiation information received from the irradiation apparatus. By switching between these different parameter sources based on timing and availability, the system optimizes both processing speed and correction accuracy.
3Measurement precision
If the radiography control apparatus always waits for irradiation information before performing image processing, then the accuracy of image processing is improved, but operator convenience deteriorates due to reprocessing requirements
Solution Approach 1:
The system performs preliminary scattered radiation correction using fixed information stored in advance, before the operator completes inputting irradiation information or before the irradiation apparatus sends the data. This eliminates the need for operator-initiated reprocessing and automatically provides accurate correction when the actual irradiation information is available.
Data Source
AI summary
A radiography control apparatus includes a storage; a communicator that obtains irradiation information from an irradiation apparatus; and a hardware processor that: upon determining that the communicator obtains the irradiation information before a specific timing, executes image processing based on the irradiation information obtained from the communicator; and upon determining that the communicator does not obtain the irradiation information before the specific timing, executes the image processing based on information stored in advance in the storage.
