Radiography System Switch Element Control for Standby Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiography systems fail to shorten standby time between shooting actions without degrading video quality when serial radiography is followed by another serial radiography, as they do not effectively manage the transition between different imaging modes.
Innovation Solution
A radiography system that includes an image former for serial radiography, a determiner to identify subsequent test actions, and an operation controller that maintains the switch element's state similar to previous serial radiography, allowing for immediate transition to the next radiography without prolonged standby times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device is driven for a predetermined time before actual radiation to obtain accurate offset data, then the offset data accuracy is improved, but the standby time between shooting actions increases
Solution Approach 1:
The patent applies preliminary action by performing the switch element driving operation during the radiation exposure period itself, rather than requiring a separate preliminary driving period. The offset data acquisition is integrated into the radiation shooting process, allowing the system to prepare offset data concurrently with image acquisition, thus eliminating the need for extended standby time while maintaining offset data accuracy.
Solution Approach 2:
The patent ensures continuity of useful action by making the image former begin turning the switch element on/off in the same manner as in the previous serial radiography, right before the start of the next test action. This continuous operation allows the system to maintain readiness for offset data acquisition without interrupting the radiography workflow, thereby reducing standby time while preserving measurement precision.
2Reliability
If the time intervals are controlled to prevent device life shortening and detection characteristic changes, then device reliability is improved, but the standby time between shooting actions increases
Solution Approach 1:
The patent applies dynamics by making the operation mode of the image former adaptive based on the type of test action. The system dynamically adjusts its operation: for serial radiography, it maintains continuous switch element driving to reduce standby time, while for other test actions, it can extend the driving period to ensure reliability. This dynamic adjustment allows the system to optimize between reliability and time efficiency based on operational context.
Solution Approach 2:
The patent changes the operational parameters of the image former based on the determined test action type. When serial radiography is detected, the system changes the parameter of switch element driving frequency and timing to match the rapid succession requirements, thereby reducing standby time while maintaining device reliability through controlled parameter adjustment rather than extended idle periods.
3Manufacturing precision
If the system performs full initialization drive before still image shooting, then the imaging quality is improved, but the transition time from video shooting increases
Solution Approach 1:
The patent applies preliminary action by maintaining the switch element driving operation continuously during video shooting, so that when transition to still image shooting is needed, the preliminary initialization work has already been performed. This eliminates the need for additional full initialization drive, reducing transition time while preserving imaging quality through the ongoing preparatory operations.
Solution Approach 2:
The patent uses periodic action by continuing the periodic switching of the switch element during video shooting at the same frequency and pattern. This periodic operation serves dual purposes: it maintains the imaging workflow and simultaneously performs the initialization function needed for high-quality still image shooting, thereby reducing transition time without compromising imaging quality.

AI summary
A radiography system includes an image former, a first determiner, and an operation controller. The image former performs serial radiography of repeatedly generating a frame that constitutes a video. The first determiner determines whether a next test action is the serial radiography. The operation controller makes the image former begin turning a switch element on/off in a same manner as a manner in the serial radiography before start of the next test action in a case where the first determiner determines that the next test action is the serial radiography.
