In 1895, Wilhelm Roentgen unintentionally discovered x-rays and
produced the first x-ray image, which was of his wife’s hand. Thomas Edison then took Roentgen’s discovery of
the x-ray a step further and introduced conventional fluoroscopy the following year of
1896. Unlike traditional radiography,
fluoroscopy is real-time, dynamic x-ray imaging allowing the radiologist to watch moving
structures and functions within the human body by use of x-rays penetrating the
body and the images being displayed on a hi-definition digital monitor
providing an x-ray “movie” experience. Interested

“Take 2, 3, 4, etc.” and reveal the greatness of Fluoro.
The fluoroscope unit is similar to that of a general x-ray unit; however there is one key difference-- it's flipped flopped. On a regular x-ray unit, the tube is positioned above the patient table and the image receptor is underneath the patient. On the other hand, the fluoro x-ray tube is located underneath the patient table and the image receptor above. Here is a simple description of each of the components of the fluoroscopy unit: 1. Generator : This is important for converting the alternating current (AC) to direct current (DC) which then allows for the adjustment of mAs and kVp as well as to select pulsed fluoroscopy (ASRT, 2010). 2. X-Ray Tube : This is contained within a glass or metal tube to help prevent leakage and scatter radiation. DC will flow from cathode to anode; and once the electrons reach the anode, x-rays are produced. 3. Collimator: Blades that allow for modification of shape/size of x-ray fie...
