Separation of the nail from the distal nailbed in conjunction with sun exposure and simultaneous use of drugs such as antibiotics.  

In radiography, an electronic vacuum tube designed to convert light photons into electrical pulses. It is used to digitize incoming light photons prior to the creation of computerized images in nuclear medicine and other imaging modalities. An electron tube is employed to amplify the radiographic image of faint intensity that is visible on a fluorescent…

A device for measuring the intensity of light.  

The use of light to treat certain conditions.  

Dissolution or disintegration under stimulus of light rays.  

The power of an object to become luminescent when acted on by light.  

The characteristic of being destroyed or inactivated by light.  

Reacting with motion to stimulation by light.  

Photographing the images seen during fluoroscopic examination. The procedure involves capturing the radiographic image using a photographic technique. To illustrate, a stream of radiation passes through the chest and impinges upon a dedicated fluoroscopic screen located at the terminus of a light-tight enclosure. At the opposite end, a camera captures the projected fluoroscopic image onto…
