Is there a recommended timeframe for completing a precision assessment?
The intent of a precision assessment is to determine the precision of the technologist on a particular machine without introducing uncontrolled variables. Therefore, there is no recommended timeframe that each technologist must complete their collection of duplicate or triplicate subjects, providing their technique for scanning is not changing. Some have recommended completing the scans within a 30 day period to minimize the possibility that equipment failure (which can happen gradually over several months before being detected) will influence data. If an equipment failure and subsequent major repair occurs during the collection of data for a precision assessment, pre-failure data may need to be discarded and then reacquired depending on the nature of the failure.
