Image quality and dose management in digital radiography: a new paradigm for optimisation

摘要: The advent of digital imaging in radiology, combined with the explosive growth technology, has dramatically improved techniques. This led to expansion diagnostic capabilities, both terms number procedures and their scope. Throughout world, film/screen radiography systems are being rapidly replaced systems. Many progressive medical institutions have acquired, or considering purchase computed strorage phosphor plates direct flat panel detectors. However, unknown some users, these devices offer a new paradigm opportunity challenges. Images can be obtained at lower dose owing higher detective quantum efficiency (DQE). These fundamental differences comparison conventional film/screens necessitate development strategies for quality optimisations. A set referral criteria based upon three levels is proposed.
