Fluoroscopy's origins and radiography's origins can both be traced back to 8 November 1895, when Wilhelm Röntgen, or in English script Roentgen, noticed a barium platinocyanide screen fluorescing as a result of being exposed to what he would later call X-rays (algebraic x variable signifying "unknown"). Within months of this discovery, the ...
In 1999, Time placed Shoe-Store X Rays on a list of the 100 worst ideas of the 20th century. [29] [30] A shoe-fitting fluoroscope appeared on a 2011 episode of the History series American Restoration. [31] Its radionuclide source was found to be so dangerous that it was removed and replaced with a static X-ray. [32]
William Lawrence Bragg proposed a model in which the incoming X-rays are scattered specularly (mirror-like) from each plane; from that assumption, X-rays scattered from adjacent planes will combine constructively (constructive interference) when the angle θ between the plane and the X-ray results in a path-length difference that is an integer ...
An X-ray image intensifier (XRII) is an image intensifier that converts X-rays into visible light at higher intensity than the more traditional fluorescent screens can. Such intensifiers are used in X-ray imaging systems (such as fluoroscopes) to allow low-intensity X-rays to be converted to a conveniently bright visible light output. The ...
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
Flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. They are used in both projectional radiography and as an alternative to x-ray image intensifiers (IIs) in fluoroscopy equipment.
The coronary angiography is performed under local anaesthesia. The patient is awake during the procedure. An incision is made in the groin, wrist, or arm, and a catheter is inserted into the artery through it. An X-ray is used to guide the catheter to the area of blockage. A dye is inserted through the catheter to make the places of blockage ...
