Computed Radiography with Storage Phosphorus Imaging Plates
Computed radiography with photostimulable storage foils stores X-ray images in flexible foils and reads them out via laser scanning to obtain digital inspection data.
Physicochemical Mechanism of Action
X-ray radiation is projected onto photostimulable storage foils. The foils store the radiation information in a chemical binding state. To read out, a laser is used to release the stored information and capture it as a digital image.
Metallurgical Relevance & Risks in Welding
This technique enables precise and low-loss digitization of X-ray images. It is particularly useful for inspecting weld quality because it provides detailed information about internal structures and potential defects. An error during readout or storage can lead to inaccurate images, which impairs diagnosis.
Workshop Practice & Instructions
Use high-quality photostimulable storage foils and make sure the laser device is correctly calibrated. Perform the readout in a dark environment to minimize interference. If needed, calibrate the system to ensure image accuracy.
