Should IMRT patient QC be done field-by-field or for the composite plan?
❑ Assume a 5 field plan each beam contributes with 1/5 to the target
❑ Each beam are delivered within 3 % of calculation ❑ Except for one that is 15% off. ❑ This plan will not pass field-by-field QC ❑ For a composite plan you will not detect this, the plan is within 3%!!!
