: 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 energy into electronic signals that can be processed by a computer. : Digital Radiography: Physical Principles and Qu...

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

: 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). : : Images consist of a matrix of
