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.
Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures. It plays an important role in the science and technology needed ...
The field of radiologic technology (also known as x-ray technology) is projected to grow 17% and faster than the national average rate through 2018, to support America's aging population's health
The voltages used in diagnostic X-ray tubes range from roughly 20 kV to 150 kV and thus the highest energies of the X-ray photons range from roughly 20 keV to 150 keV. [ 88 ] Both of these X-ray production processes are inefficient, with only about one percent of the electrical energy used by the tube converted into X-rays, and thus most of the ...
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
X-ray detector. Acquisition of projectional radiography, with an X-ray generator and an imaging detector. X-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays. Detectors can be divided into two major categories: imaging detectors (such as photographic plates and X-ray film ...
The current Philippine military ranks are inspired partially by the first military insignia used by the military forces during the Philippine Revolution of 1896 and the Philippine–American War, and the insignia used by the Philippine Constabulary raised in 1902 during the final days of the Philippine–American War, which was basically the same style of insignia used by the United States ...
