Conclusions: PBC calculates hot spot dose-volume less accurate than AAA in HT tissues.Therefore hot spot information is not precise in PBC plans than AAA plans and max dose constrains could be above than intended.Additionally, PBC could calculate OAR doses less than actual, which might cause over doses and morbidity in some OARs, such as spinal cord.Consequently AAA should be preferred to PBC for target including HT such as lung.
