In response to the increasing use of digital radiography to assess the structural integrity of engineered assets, TWI is launching a new course: ‘An Appreciation of Advanced Radiography'.
Digital radiography is an advanced technology based on digital detector systems in which the x-ray image is displayed directly on a computer screen. It removes the need to use traditional photographic film or intermediate scanning and there is no development of chemicals.
Digital radiography is applied to non-destructive testing (NDT) in order to assist in the accurate location, characterisation and sizing of flaws that can be found in structural components such as pipeline, pressure vessels and printed circuit boards.
Advantages of using digital radiography rather than traditional radiography techniques include shorter set-up times, automated inspection and faster generation of X-ray images.
Comprising a balance of theory and practical elements, TWI’s new course has been designed to meet the needs of radiographic testing operators qualified to at least level 1 CSWIP/PCN, who are engaged in radiographic testing and interpretation, and would like to enhance their knowledge by incorporating digital radiography into their skills set. It is also ideal for personnel engaged in the supervision, control and interpretation of radiographic images who would like to expand their capabilities to include digital radiography.
The four-day course includes insights into:
- computerised radiography (CR), a process that uses photostimulable phosphors imaging plates (PSPs) to capture latent radiographic images which can subsequently be digitised
- digital radiography using digital flat panel detector technology, and;
- computed tomography (CT), a related evaluation technique outputting 2D and 3D cross-sectional images of an object from flat x-ray images, which provides an ideal examination tool when the primary goal is to locate and size, planar and volumetric detail in three dimensions.
