When ____________________ in performance is observed, and corrective action is taken, it is important to verify that performance has returned to normal levels.

____ analysis is a time-honored method for assessing and improving quality of imaging operations.

____________________ in DR causes an increase in quantum mottle and a loss of contrast in dense features.

A simple ____________________ error in selecting the wrong patient or wrong examination from the worklist creates a condition that may be more difficult to detect than a typographical error.
