Digital radiography is being rapidly adopted in the field of diagnostic radiology because of its distinctive advantages over film radiography, such as reduced radiation exposure, decreased working time, applicability of image enhancement, less space needed for storage, electronic transmission, chemical-free processing and so on. The use of digital radiography technology in orthodontics is also getting popular.
The current digital radiographic technologies available in orthodontics are broadly categorized into CR(Computed Radiography) which uses imaging plate as an alternative for film cassette, and DR(Digital Radiography) which can directly acquire images. Besides, there are film scanning and state-of-the-art technologies employing flat panel detectors. The most common method in current cephalometric DR is the one with CCD sensor complex and it is divided into one shot record and slit beam scan technique. These individual technologies have their own unique characteristics. To be helpful in selection and application of the digital radiographic equipment in orthodontics, the authors described the basic principle of the technologies and suggested the method of system integration.
