title = "Dosimetric errors of TPS calculations without correction for heterogeneity - A study using CIRS thorax phantom",
abstract = "The magnitude of the error in dose calculation using a commercial treatment planning system (TPS) without correction for tissue heterogeneity was assessed. A CIRS Thorax anthropomorphic phantom was used for the study. The phantom was CT scanned, treatment planned and treated with 10 MV photon beams. Dose at points of interested in the phantom was measured and compared with TPS calculation. Significant discrepancies of up to 8% between calculated and measured doses were observed. The results of our experiment indicate that treatment planning with TPS without correction for tissue heterogeneity should be avoided.",
