Projection Radiography

computed radiography (CR) digital systemsThe CR cassette is a direct swapout for screen film cassettes in ahospital, and thus transition to CRfrom screen film is straightforwardlogistically . CR imaging is alsousable in the portable x-rayenvironment, which can reduceretake films and save cost.Computed radiography (CR) makes use of an imaging plate, which iscomprised of a photo-stimulable phosphor, typically BaFBr (barium fluorobromide).The latent image is recorded onto the imaging plate by x-rayexposure, and is read-out using a laser scanning system called a CR reader.19
