Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single wired interface is used to exchange both AEC signals and other signals between the source controller and the electronic cassette, then device complexity is reduced, but signal interference occurs and reliability of radiation stopping deteriorates
Solution Approach 1:
The single wired interface is segmented into two separate interfaces: one dedicated to AEC signals (radiation stopping signals) and another for other signals. This segmentation prevents signal interference while maintaining system reliability, directly resolving the contradiction between device complexity and radiation stopping precision.
2Ease of operation
If signals are exchanged through a shared interface, then ease of operation is improved, but signal interference causes delays in radiation stopping
Solution Approach 1:
By dividing the shared interface into separate dedicated interfaces for AEC signals and other signals, the system eliminates signal interference that caused delays. The dedicated AEC interface ensures timely radiation stopping while the other interface handles additional communications, resolving the contradiction between operational simplicity and stopping time.
3Adaptability or versatility
If sensors from different manufacturers are integrated without separate interfaces, then adaptability is reduced, but device complexity remains low
Solution Approach 1:
The segmentation of interfaces allows each interface to be optimized for specific signal types, enabling better compatibility with different sensor systems from various manufacturers. The dedicated AEC interface standardizes critical signal exchange while the other interface accommodates manufacturer-specific variations, resolving the contradiction between adaptability and device complexity.
Data Source
AI summary
A source controller unit for controlling an x-ray source is provided with a detection signal interface for receiving detection signals from detective pixels of an electronic cassette or an integrated value of the detection signals only, or an interface for receiving a radiation stopping signal only. The source controller unit receives other radiation signals than the radiation stopping signal, such as a radiation admitting signal, through a radiation signal interface. The source controller unit uses the detection signals, the integrated value thereof, or the radiation stopping signal as exposure control signals for stopping radiation from the x-ray source. Since the exposure control signals are received on the specific interface therefor, the source controller unit does not need signal sorting operation nor receive different kinds of signals at the same time, improving the speed of radiation stopping procedure.
