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. 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. : Uses a photostimulable phosphor plate within a cassette

: 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.

: Digital detectors have a wide dynamic range , meaning they can capture a vast range of X-ray exposures. Detective Quantum Efficiency (DQE) measures how efficiently the system converts X-rays into a quality image; higher DQE results in excellent contrast at lower radiation doses.
