Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging systems face instability in wireless communication between the imaging device and control device, leading to delayed or missed instructions for X-ray irradiation, resulting in wasted radiation and increased patient exposure.
Innovation Solution
The system employs a radiographic imaging device that transmits imaging start instructions multiple times via wireless communication during a response wait period, and a control device that irradiates radiation only upon receiving these instructions multiple times, ensuring stable image capture even in unstable communication conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic cassette transmits imaging start instruction information only once to the console, then the communication protocol is simple, but the radiographic image capture becomes unstable when wireless communication is used
Solution Approach 1:
The electronic cassette transmits the imaging start instruction information in advance multiple times before the actual imaging begins. This preliminary repeated transmission ensures that the console receives the instruction even if some transmissions are lost due to wireless communication instability, thereby improving reliability without requiring complex retransmission protocols.
Solution Approach 2:
The imaging start instruction information is transmitted periodically at predetermined intervals during a specified period before imaging starts. This periodic transmission pattern allows the system to maintain simplicity while ensuring at least one transmission succeeds in unstable wireless conditions, resolving the contradiction between reliability and complexity.
2Productivity
If the electronic cassette transitions to charge accumulating state immediately upon sensing X-ray start during resetting operation, then imaging speed improves, but radiation waste increases
Solution Approach 1:
The electronic cassette performs preliminary resetting operations and prepares the charge accumulating sections in advance before X-ray irradiation begins. By completing the resetting operation just before imaging starts (guided by the multiple transmitted instructions), the system achieves fast imaging readiness without wasting radiation during the transition phase.
Solution Approach 2:
The system uses feedback from the multiple transmitted imaging start instructions to coordinate the timing of the resetting operation completion and charge accumulating state transition. This feedback mechanism ensures the electronic cassette transitions to the charge accumulating state at the optimal moment when X-ray irradiation is confirmed to have started, balancing speed and radiation efficiency.

AI summary
There is provided a radiographic imaging system including: a radiographic imaging device including a generating section that captures a radiographic image expressed by irradiated radiation and generates image information expressing the captured radiographic image, and a first communication section that transmits, plural times and by wireless communication and even during a response wait time period, imaging start instructing information that instructs starting of imaging when preparations for capturing a radiographic image by the generating section have been completed; and a control device having a second communication section that can communicate by wireless communication with the first communication section, and a control section that controls a radiation irradiating section such that radiation is irradiated with respect to the radiographic imaging device in a case in which the second communication section receives any of the imaging start instructing information that are transmitted plural times from the first communication section.
