Image Detector Temperature Control During Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems in the medical field face challenges in maintaining high-quality image output due to noise introduced by temperature regulation controls during the reading process, which can degrade the quality of radiation images.
Innovation Solution
An image detecting device with a temperature regulation control unit that halts or relaxes temperature regulation operations based on image information output detection signals, preventing noise from being added to the radiation image information during image reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature regulation control operation is performed continuously on the image detector, then the image detector maintains predetermined temperature to prevent dew condensation, but noise is added to the radiation image during reading
Solution Approach 1:
The temperature regulation control operation is performed periodically rather than continuously. The control unit activates temperature regulation only during periods when image reading is not occurring, and suspends it during image reading periods. This periodic operation maintains temperature control effectiveness while eliminating noise interference with the radiation image quality.
2Stability of the object's composition
If temperature regulating means is energized during image reading, then temperature control is maintained, but drive signal is added to image information reducing quality
Solution Approach 1:
The temperature regulation system dynamically adjusts its operation based on the reading state of the image detector. The control unit monitors whether the image detector is in a reading state and accordingly activates or suspends temperature regulation. This dynamic control allows the system to maintain temperature stability during non-reading periods while preventing drive signal interference during reading periods, thereby preserving image quality.
3Object-affected harmful factors
If temperature regulation control operation is suspended during reading, then noise is prevented from being added to the radiation image, but temperature control is not maintained
Solution Approach 1:
The temperature regulation control operation is activated in advance before image reading begins. By detecting the upcoming reading period and suspending temperature regulation beforehand, the system prevents noise from being added to the radiation image. The temperature control is then reactivated after reading completes, ensuring temperature stability is maintained during non-reading periods while preventing interference during reading.
