Front end technology and equipment is the same as used for conventional radiography, the difference is in recording the image and the use of phosphor screens. When exposed to X or gamma ray electrons phosphor crystals are excited and trapped in a semi-stable higher energy state. The radiation exposed flexible phosphor plate is then processed through a laser scanner, delivering the image onto a high-resolution monitor. This digital image can be enhanced and analysed whilst the phosphor screen is automatically erased for immediate reuse. The image can then be interpreted, reported and digitally stored for future retrieval or analysis.
