Solution Overview
Problem
X-ray devices with portable detectors and wireless interfaces face ambiguities in operation, leading to potential incorrect radiation exposure due to uncertainties in detector registration, location, and transmission quality, which can result in increased radiation doses for subjects and staff.
Innovation Solution
A method for controlling x-ray devices that involves obtaining and storing status information about each detector in a database, allowing for reliable registration and deregistration processes, and ensuring accurate operation by using a combination of wireless interfaces with different ranges for data transfer and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless interface is used for data transmission between x-ray detectors and base station, then flexibility and ease of operation are improved, but reliability of data transmission deteriorates
Solution Approach 1:
The system continuously monitors transmission quality parameters (signal strength, packet loss, interference levels) and provides feedback to the base station. The base station uses this feedback to dynamically adjust transmission parameters, select optimal communication channels, or trigger retransmission protocols when quality degrades, thereby maintaining reliable data transmission over the wireless interface.
Solution Approach 2:
The system performs preliminary checks of transmission quality before initiating critical data transfers. Buffer memory is allocated in advance to store data packets, and error correction codes are pre-applied to transmitted data. These preparatory measures cushion against potential transmission failures and ensure data integrity even when wireless conditions are suboptimal.
2Adaptability or versatility
If multiple x-ray detectors are registered to a base station for flexible operation, then adaptability is improved, but operational ambiguities and errors increase
Solution Approach 1:
The base station acts as an intermediary that manages all communications and assignments between multiple detectors and the control system. It maintains a registration database that tracks which detectors are available, their operational status, and current assignments. This central mediation eliminates ambiguities by providing a single source of truth for detector availability and usage, enabling flexible interchangeability without operational errors.
Solution Approach 2:
Each x-ray detector is equipped with unique identification and status reporting capabilities that allow it to self-announce its availability and operational state to the base station. The detector automatically provides information about its readiness, current assignments, and transmission quality, enabling the system to manage multiple detectors autonomously without manual intervention, thus maintaining reliability while enhancing adaptability.
3Reliability
If real-time status monitoring of all detectors is implemented, then operational reliability is improved, but device complexity and data management burden increase
Solution Approach 1:
The base station is designed as a multi-functional system that simultaneously performs data acquisition from multiple detectors, real-time status monitoring, transmission quality assessment, automatic assignment management, and error detection. By consolidating these diverse functions into a single integrated platform, the system achieves comprehensive reliability without proportionally increasing complexity, as the base station handles all tasks through unified software modules and data structures.
Solution Approach 2:
The system monitors key parameters (transmission quality, detector status, assignment state) and automatically adjusts operational parameters based on predefined thresholds and algorithms. When parameters indicate potential issues, the system dynamically changes transmission rates, reassigns detectors, or triggers alerts, thereby maintaining reliability through automated parameter management rather than complex manual oversight.
Data Source
AI summary
A method controls an X-ray apparatus which contains a base station and at least one X-ray detector, wherein status information about the at least one X-ray detector is obtained. The status information is deposited in a database of the base station and the X-ray apparatus is controlled on the basis of the status information from the database.
