RADIATION IMAGING APPARATUS, RADIATION IMAGING SYSTEM AND CONTROL METHOD OF RADIATION IMAGING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17873501 titled 'RADIATION IMAGING APPARATUS, RADIATION IMAGING SYSTEM AND CONTROL METHOD OF RADIATION IMAGING APPARATUS
Simplified Explanation
The radiation imaging apparatus described in the patent application includes:
- A radiation detector with a pixel array capable of detecting radiation as electric signals.
- An AEC sensor used for automatic exposure control of radiation from a radiation generating apparatus.
- A notifying unit that alerts the radiation generating apparatus when the dose value of radiation incident on the pixel array reaches a threshold value.
- A threshold value setting unit that sets the threshold value for second radiation imaging, based on pixel values detected by the pixels in the first radiation imaging.
Potential applications of this technology:
- Medical imaging: The radiation imaging apparatus can be used in medical imaging devices such as X-ray machines to provide accurate and controlled exposure to radiation for diagnostic purposes.
- Industrial inspection: This technology can be applied in industrial settings for non-destructive testing and inspection, where radiation imaging is used to detect flaws or defects in materials or products.
- Security screening: The apparatus can be utilized in security systems for screening baggage or cargo, where radiation imaging helps identify potential threats or contraband items.
Problems solved by this technology:
- Automatic exposure control: The AEC sensor and threshold value setting unit ensure that the radiation exposure is controlled and optimized, preventing overexposure or underexposure in both medical and industrial imaging applications.
- Dose monitoring: The pixel array and threshold value reached notification system allow for real-time monitoring of the radiation dose incident on the detector, ensuring safety and preventing excessive radiation exposure.
Benefits of this technology:
- Improved image quality: By performing automatic exposure control based on pixel values, the radiation imaging apparatus can produce high-quality images with optimal contrast and resolution.
- Radiation dose optimization: The threshold value setting unit helps in optimizing the radiation dose delivered to the patient or the inspected object, minimizing unnecessary exposure while maintaining image quality.
- Enhanced safety: The dose monitoring capability and threshold value reached notification system ensure that radiation exposure remains within safe limits, reducing the risk of radiation-related health issues for both patients and operators.
Original Abstract Submitted
