: Captures images directly using fixed sensors. These systems can use direct conversion (converting X-rays to electrical charge via amorphous selenium) or indirect conversion (converting X-rays to light first using a scintillator like cesium iodide).

Digital radiography (DR) has revolutionized medical imaging by replacing traditional film-based systems with digital sensors that provide immediate image acquisition and high-speed processing. Understanding its physical principles and maintaining strict quality control (QC) is essential for maximizing diagnostic quality while minimizing patient radiation dose.

: Uses a photostimulable phosphor plate within a cassette. X-rays create a "latent image" that is later scanned by a laser to release light, which is then digitized. : Captures images directly using fixed sensors

QC programs ensure that equipment consistently adheres to performance standards and safety regulations. QC programs ensure that equipment consistently adheres to

: Images consist of a matrix of small squares called pixels . Smaller pixels and larger matrices generally improve spatial resolution , allowing for finer detail.
