Computed Radiography with Storage Phosphorus Imaging Plates
Computed radiography with storage foils uses flexible X-ray storage foils as detectors. After exposure, the foils are read out using a laser beam and digitized.
Physicochemical Mechanism of Action
Computed radiography with storage foils uses flexible X-ray storage foils, which undergo a specific chemical change when exposed to X-rays. This change is read out by a laser beam and converted into an electronic signal, which is then digitized.
Metallurgical Relevance & Risks in Welding
This technique allows precise visualization of the internal structure of workpieces. It is especially useful for controlling weld quality and detecting internal defects or porosity. Incorrect laser settings or radiation intensity can lead to inaccurate results, which impairs diagnosis.
Workshop Practice & Instructions
To perform accurate computed radiography, the X-ray storage foils must be correctly positioned, and the radiation intensity as well as the laser beam must be precisely adjusted. The exposure time should be long enough to capture sufficient information but not too long to overexpose the material. Results should be regularly reviewed and calibrated to ensure image quality.
