X-ray Digital Radiography Applications
Digital radiography (DR) offers advantages over traditional film-based techniques, allowing for faster image acquisition, enhanced image manipulation, and easier storage and sharing of inspection results. In digital radiography, X-ray radiation passes through the object being inspected and is captured by a digital detector. These detectors can be either flat-panel detectors (FPDs) or computed radiography (CR) plates. FPDs directly convert X-rays into electrical signals, while CR plates store the X-ray image as a latent image that is later processed digitally.
Digital radiography systems allow for immediate image processing, including enhancement, zooming, and analysis, which can help in identifying defects more accurately and efficiently. Faster image acquisition than traditional film-based radiography improves workflow efficiency and reduces inspection time, leading to cost savings and increased productivity.
Computed Radiography systems consist of three main components: an X-ray source, a phosphor imaging plate, and a reader/scanner. When the X-ray source emits radiation, it passes through the object being inspected and interacts with the imaging plate. The phosphor material in the imaging plate absorbs X-ray energy and stores it as a latent image.
After exposure, the imaging plate is removed from the cassette and inserted into the reader/scanner. Inside the scanner, a laser beam scans the imaging plate, stimulating the release of stored energy as visible light. This emitted light is captured by a photomultiplier tube or solid-state detector, converted into electrical signals, and digitized to create a digital radiographic image.
Computer Radiography Applications
CR is a versatile and effective digital imaging technique for industrial non-destructive testing applications, offering numerous advantages such as digital workflow, flexibility, and image enhancement capabilities. With ongoing technological advancements and integration with AI-driven solutions, CR continues to play a vital role in ensuring the integrity and safety of industrial components and structures.
