X-ray phosphors for medical

X-ray imagers consist of a phosphor in direct contact with the surface of an array of a-Si H photodiodes. The device is a matrix-addressed array, in which each imaging pixel consists of a photodiode and a TFT [647-649]. These X-ray imagers are very suitable for static and dynamic imaging in medical diagnosis. 

For medical (X-ray) and military (infrared) uses, X-ray and IR fluorescence and image intensifiers were developed. An input phosphor converts X-ray (or IR) photons to electrons, which are electronically intensified and...

Some uses of the lanthanides, such as in certain steel alloys or as cigarette lighter flints, require no separation of the metals as obtained from certain ores. In other applications, such as phosphors for television screens, medical immunoassays, X-ray photography, and, of course, the study of their chemistry, the individual elements must be separated.7...
