Direction of Radiographic Education
Although many of the methods and techniques developed
over a century ago remain in use, computers are slowly becoming
a part of radiographic inspection. The future of radiography will
likely see many changes. As noted earlier, companies are performing
many inspections without the aid of film.
Radiographers of the future will capture images in digitized
form and e-mail them to the customer when the inspection has been
completed. Film evaluation will likely be left to computers. Inspectors
may capture a digitized image, feed them into a computer and wait
for a printout of the image with an accept/reject report. Systems
will be able to scan a part and present a three-dimensional image
to the radiographer, helping him or her to locate the defect within
Inspectors in the future will be able to peal away layer after
layer of a part to evaluate the material in much greater detail.
Color images, much like computer generated ultrasonic C-scans
of today, will make interpretation of indications much more reliable
and less time consuming.
techniques and materials will need to be revised and updated to
keep pace with technology and meet the requirements of industry.
These needs may well be met with computers. Computer programs
can simulate radiographic inspections using a computer aided design
(CAD) model of a part to produce physically accurate simulated
x-ray radiographic images. Programs allow the operator to select
different parts to inspect, adjust the placement and orientation
of the part to obtain the proper equipment/part relationships,
and adjust all the usual x-ray generator settings to arrive at
the desired radiographic film exposure.
Computer simulation will likely have its greatest impact in the
classroom, allowing the student to see results in almost real-time.
Simulators and computers may well become the primary tool
for instructors as well as students in the technical classroom.
