Reason for recall
If the beam model has a highly asymmetric primary source, it is not correctly taken into account in the calculation of DMLC fields when the collimator is rotated. This could lead to potentially significant overdosage at delivery. The user must be aware of the issue to avoid incorrect dose calculations during treatment planning.
