-"In many ways, radiography has changed little from the early days of its use."

-"We still capture a shadow image on film using similar procedures and processes technicians were using in the late 1800's."

-"Today, however, we are able to generate images of higher quality and greater sensitivity through the use of higher quality films with a larger variety of film grain sizes."

- "Film processing has evolved to an automated state, producing more consistent film quality by removing manual processing variables."

-"Electronics and computers allow technicians to now capture images digitally."

-"The use of "filmless radiography" provides a means of capturing an image, digitally enhancing, sending the image anywhere in the world, and archiving an image that will not deteriorate with time."

-"Technological advances have provided industry with smaller, lighter, and very portable equipment that produce high quality X-rays."

-"The use of linear accelerators provide a means of generating extremely short wavelength, highly penetrating radiation, a concept dreamed of only a few short years ago."

-"While the process has changed little, technology has evolved allowing radiography to  be widely used in numerous areas of inspection."

-"Radiography has seen expanded usage in industry to inspect not only welds and castings, but to radio graphically inspect items such as airbags and canned food products."

-"Radiography has found use in metallurgical material identification and security systems at airports and other facilities."

-"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 the part."

-"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"
