Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems in the medical field face issues with energy wastage due to continuous temperature regulation, which degrades image quality by adding noise to the radiation images.
Innovation Solution
An image detecting device with a temperature regulation controller that stops or relaxes temperature regulation during image reading and resumes it after a preset time, preventing noise from being added to the image information and conserving energy by minimizing unnecessary temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If temperature regulation control is continuously performed on the image detector, then the image detector temperature is maintained at a predetermined level, but noise is added to the image information degrading image quality
Solution Approach 1:
The temperature regulation controller operates periodically rather than continuously. It performs temperature regulation control during periods when image information is not being read, and stops or relaxes control during image reading periods. This periodic operation eliminates noise contamination while maintaining temperature stability through timed cycles of regulation and relaxation.
2Reliability
If temperature regulation control is continuously performed on the image detector, then the desired performance of the image detector is achieved, but energy is wastefully consumed
Solution Approach 1:
The system implements periodic temperature regulation by timing the control operations to occur only during non-imaging periods. The controller alternates between active temperature regulation and relaxed control states, ensuring detector performance is maintained when needed while eliminating wasteful energy consumption during image acquisition and reading phases.
Solution Approach 2:
The temperature regulation controller automatically adjusts its operation based on the reading status of the image detector. It detects when image information is being read and autonomously stops or relaxes temperature control without external intervention, then resumes control after a preset time period,实现ing self-managed energy optimization.
3Object-affected harmful factors
If temperature regulation control is stopped during image reading, then noise is prevented from being added to the image, but the image detector temperature may deviate from the predetermined temperature
Solution Approach 1:
The temperature regulation controller is configured to perform temperature regulation in advance during periods when the image detector is not reading image information. By pre-regulating the temperature before the imaging phase begins, the system ensures the detector is properly conditioned while avoiding temperature control interference during actual image acquisition.
Solution Approach 2:
The system temporarily skips temperature regulation control during the critical image reading phase, accepting short-term temperature deviation to prevent noise contamination. After image reading completes and a preset time has elapsed, the controller resumes regulation to restore proper temperature conditions for the next imaging cycle.

AI summary
An image detecting device includes an image detector, a temperature regulation controller, an image information output detector, and a timer, wherein the temperature regulation controller stops or relaxes the temperature regulation control operation on the image detector based on the image information output detection signal input thereto from the image information output detector, and resumes or stops relaxing the temperature regulation control operation on the image detector when the timer has measured a preset period of time after the temperature regulation control operation has been stopped or relaxed.
