Radiography Master Mind
Wilhelm Conrad Roentgen

X-rays History

 

X-rays weren't developed, they were discovered, and quite accidentally. throughout the 1890s and 1880s, several university physics laboratories were investigating the conduction of cathode rays, or electrons, through an oversized, partly evacuated glass tube referred to as Crookes tube.


Effect of X-Ray on Radiology 

 

For seven decades when Roentgen’s discovery of x-rays in 1895, diagnostic radiology remained a comparatively stable field of study and practice. A very great changes throughout that point can be counted on one hand. The Crookes tube, the radiographic grid, radiographic intensifying screens and image intensification.
However, many more innovative types of medical imaging have inherit routine use in medical imaging: like these expensive machines in radiology: Computed Tomography, Computed Radiography (X-ray Machines), Digital Radiography, Fuoroscopy, and Multislice spiral computed axial tomography,  are actually spectacular advances in computer technology, x-ray tubes and image receptor design have created these innovations possible, and continue to develop the diagnostic imaging sciences.

Crookes Tube

 

Sir Sir William Crookes was an English man from a rather humble background who was a self-taught genius.
The tube that bears his name was the forerunner of recent fluorescent lamps and x-ray tubes. there have been many different kinds of crookes tube. Most of them were capable of producing x-rays. Wilhelm Roentgen was experimenting with a kind of Crookes tube when he discovered x-rays.
On november 8, 1895, Roentgen was busy working in his physics laboratory at wurzburg University in Germany. He had darkened his laboratory and fully enclosed his Crookes tube with black photographic paper in order that he could better view the results of the cathode rays within the tube. Accidentally a plate coated with barium platinocyanide, it’s a fluorescent material, happen to be lying on a bench top many feet from the Crookes tube. No visible light exits from the Crookes tube because of the black paper wrapping it, however Roentgen noted that the barium platinocyanide glowed no matter its distance from the Crookes tube. The intensity of the glow as the plate was brought nearer to the tube, consequently, there was a very little doubt regarding the origin of the stimulus of the glow. This glow is call called fluorescence.
Roentgen’s immediate approach to investigating this “x-light” as he referred to as it 1st, was to interpose various material like wood, aluminum and his own hand, between the Crookes tube and the fluorescing plate. The letter ”X” was for unknown. He feverishly continued these investigations for many weeks.

The First Radiographic Image

 

Roentgen’s initial investigations were extraordinarily thorough and he was able to report his expirimetal results to the scientific community before the end of 1895. For this work, in 1910 he received the Novel Prize in physics. Roentgen recognized the value of his discovery to medicine. He created and published the first medical x-ray in early 1896. it had been an image of his wife’s hand.  ----  On image a photograph of what's reported  to be the first x-ray examination in U.S., conducted in early february, 1896 in physics laboratory at Darthmouth college.


Advantage of X-ray After Discovery

 

There are several wonderful features regarding the discovery of x-rays that cause it to rank high within the events of human history. First, the discovery was unexpectedly and accidentally. Second, in all probability no fewer than a dozen contemporaries of Roentgen had previously observed x-radiation, however none of those other physicists had recognized its significance or investigated it. And thirdly, He followed his discovery with such scientific vigor that at intervals described quite a month he had represented x-radiation or x-rays with nearly all the properties we have a tendency to acknowledge recognize these days
