Is it acceptable for a technique chart to simply state that the facility is using the unit in its fully automatic AEC mode (e.g., BACE, OPDOSE, AUTO FILTER, AOP, or similar modes) for all routine examinations?
Yes. However, if such a technique chart is the only one available, the facility may not use the unit if the automatic AEC mode listed on the technique chart fails during medical physicist testing. For this reason, FDA strongly recommends that the facility develop, and have available, a technique chart that includes other AEC modes (such as fixed kVp mode) and/or manual techniques. The technique chart could then be used as a guide for the radiologic technologist in the event that the fully automatic AEC mode failed or was not suitable for use with a specific patient.
