The use of filmless laser scanner (FLS) for medical imaging can provide many benefits including improved diagnostic quality, better user interface and time and operating cost efficiency. From the beginning radiography has depended on silver-halide film for recording and displaying images. The use of phosphor as x-ray to light converter has intrigued scientists and engineers for many years and phosphors are used in many forms in a variety of applications. The acceptance of digital imaging in the medical field has triggered an increased interest in an improved and new imaging sensors for x-ray which generated new products. Phosphor plates and CCD are among the most popular sensors currently used commercially. This development is based on the use of phosphor plate which have been found to be far superior in performance and cost-effectiveness than competitive media. The laser scanner is integrated with a computerized workstation which provides image control, display and analysis as well as archiving and communication of x-ray images for the dental industry.
