Taking an X-ray image with early Crookes tube apparatus, late 1800s.. For the first three decades of medical imaging's existence (1897 to the 1930s), there was no standardized differentiation between the roles that we now differentiate as radiologic technologist (a technician in an allied health profession who obtains the images) versus radiologist (a physician who interprets them).

This process was formalized in 1929 with the debut of the society's journal, The X-Ray Technician. In 1930, the organization was renamed to the American Society of Radiographers. [2] By 1932, when the association changed its name to the American Society of X-Ray Technicians, membership had reached nearly 400.
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
In X-ray radiography and radiotherapy, it is radiographers who will carry out the imaging or treatment, while technologists may be involved in equipment testing and radiation protection activities. [1] [10] In nuclear medicine however, those with technologist or radiographer training largely have the same responsibilities. [11]

The certification of the CTX-5000 followed nine years of development. During that time the FAA invested $90 million in explosives detection and nearly $8.6 million in the specific technology. From 1995 to 1997, the CTX-5000 was tested to solve the challenges involved in integrating an explosives detection system into a baggage system and to ...
In 1974, after studies of surveillance programs for coal miners revealed unacceptable degrees of reader variability, [1] NIOSH began the "B" reader program (so named because of the Black lung or Coal Workers' X-ray Surveillance Program), with the intent to train and certify physicians in the ILO Classification system [2] (for classifying radiographs for the presence of pneumoconiosis), so as ...
