The charge of TG116, as approved by the Science Council of
AAPM, was to identify a method of providing feedback, in
the form of a standard index, to operators of digital radiographic
DR systems, which reflects the adequacy of the
exposure that has reached the detector after every exposure
event. This report is the answer to that charge and will cover
all digital radiographic image detector systems leaving digital
fluorography or fluoroscopy radioscopy for future consideration.
