(1) Basic principles of digital radiography addressing digital image characteristics, types of digital receptors in cassette-less systems and cassette-based systems, comparison of detector properties and evaluative criteria, and dynamic range versus latitude;

(2) Image acquisition addressing raw data acquisition, and image extraction and exposure indicators in cassette-less and cassette-based systems;

(3) Image acquisition errors addressing exposure field recognition, histogram analysis error, low intensity radiation response, scatter control such as coning and use of optimal exposures, and grid use including Moiré effect;

(4) Software (default) image processing addressing automatic rescaling, final image processing, effects of excessive processing, and recognition of image processing errors that affect image clarity;

(5) Fundamental principles of exposure addressing optimal receptor exposure, receptor response and detective quantum efficiency, selection of exposure factors, exposure myths associated with digital imaging systems, controlling patient exposure, monitoring patient exposure;

(6) Image evaluation addressing evidence of appropriate exposure level and exposure recognition failure or histogram analysis error, contrast, recorded detail, and artifacts;

(7) Quality assurance and maintenance issues addressing initial acceptance testing, cassette-based system reader preventive maintenance, plate maintenance, uniformity of default processing codes, and reject analysis; and

(8) Image display issues to include types of viewing monitors as compared to film/screen, picture archiving and communication systems, teleradiology, and operator responsibilities such as image annotation and manipulation, and patient confidentiality.
