Table 2.

Percentage deviation of the various dosimetric parameters describing primary and secondary PTV coverage in homogeneous and bulk density treatment plans from the heterogeneous dose distribution. The dosimetric parameters differing by 2% or more from heterogeneous calculations are shaded in blue.
