Digital radiography flat-panel detectors are key equipment for modern medical imaging diagnosis, with high resolution and low radiation dose. In order to ensure its high-precision performance and reliability, accurate calibration and maintenance are indispensable.
Calibration is the process of adjusting and confirming the accuracy of detector measurements by comparison with known reference standards. The process involves adjustments to the sensor’s sensitivity by photographing a series of test objects with known radiation doses and accuracy for comparison. The energy of the X-rays also needs to be measured, since flat-panel detectors may respond differently to X-rays of different energies. The linear response of the flat panel detector should also be ensured, ensuring that its output signal is proportional to the input signal at different radiation doses.
In order to maintain the performance of digital radiography flat-panel detectors, regular maintenance is also necessary. Frequently used detector surfaces may accumulate dust, fingerprints, or other contaminants, which can reduce the effectiveness of the detector. Regular cleaning of the detector surface is one of the important aspects of maintenance. Appropriate cleaning agents and soft cloths should be used to avoid scratching or damaging the flat panel detector. It is also necessary to check whether the connections of the flat-panel detector are worn, broken or loose to ensure the reliability of signal transmission.
During maintenance, you also need to pay attention to the replacement and repair of components. If the flat-panel detector fails or is damaged, it should be repaired or defective parts should be replaced in time to ensure the normal operation of the equipment. It is also very important to conduct various functional tests regularly, such as testing of control systems, display systems, image quality, etc. Through these tests, potential problems can be detected early and measures can be taken promptly.
The calibration and maintenance of digital radiography flat-panel detectors are crucial to ensuring their accuracy and stability. Only through correct calibration and regular maintenance and repair can the detector exert its best effect in medical imaging diagnosis and provide patients with more accurate and reliable diagnostic results.
