Subject/question	Answer options
If the dose analysis for a beam (measured vs. planned) does NOT pass your standard criteria for passing, how do you respond? (You can select more than one.)	I do nothing.
	I do the following: Examine the field(s) and TPS calculated dose to search for known limitations in the IMRT dose algorithm.
	Change the plan if necessary.
	Examine the delivery records or devices (e.g. machine parameters, log files, physical devices, etc.) for errors.
	Change the criteria to get a higher passing rate and record the justification.
	Change the criteria to get a higher passing rate without recording any justification.
	Examine the other beams in the plan to determine if the magnitude of the error might be significant.
	Not applicable, because my analyses always pass the criteria.
	I do something else.
