Out-of-field dose calculation by a commercial treatment planning system and comparison by monte carlo simulation for varian TrueBeam & #174;

Conclusion: In this work, it was observed that the TPS underestimates doses beyond the edges of treatment fields for a clinical treatment executed on a TB machine. This indicates that the out-of-field dose from TPSs should only be used with a clear understanding of the inaccuracy of dose calculations beyond the edge of the field.
