|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
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
- 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.
‘An Appreciation of Advanced Radiography’ is taking place at TWI’s state-of-the-art
engineering inspection and validation facility; TWI Technology Centre Wales, in Port Talbot
commencing on 27 November 2017. Book the course online by visiting TWI’s Training
