Digital imaging relies on the conversion of X-ray energy into electronic signals that can be processed by a computer. :
: 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 Radiography: Physical Principles and Qu...
: 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. Quality Control (QC) Procedures Digital imaging relies on the conversion of X-ray
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. : Digital detectors have a wide dynamic range
: Images consist of a matrix of small squares called pixels . Smaller pixels and larger matrices generally improve spatial resolution , allowing for finer detail.
QC programs ensure that equipment consistently adheres to performance standards and safety regulations.
