適用范圍：This part of IEC 62494 specifies definitions and requirements for the EXPOSURE INDEX ofimages acquired with DIGITAL X-RAY IMAGING SYSTEMS.This standard is applicable to DIGITAL X-RAY IMAGING SYSTEMS used in general radiography forproducing PROJECTION X-ray images for general applications, such as, but not exclusively:? computed radiography (CR) systems based on stimulable phosphors;? flat-panel detector based systems;? charge-coupled device (CCD) based systems.Image intensifier based systems and systems for mammographic or dental application are notcovered in this first edition.This standard defines the EXPOSURE INDEX only for images generated with a singleIRRADIATION event. Images generated from multiple IRRADIATIONS (e.g., tomosynthetic or dualenergyimages, multiple views on a single CR plate) are not covered.
