Monte Carlo evaluation of the effect of inhomogeneities on dose calculation for low energy photons intra-operative radiation therapy in pelvic area

• Dosimetric impact of inhomogeneities for IORT in pelvic area was evaluated. • Water non-equivalence of soft tissue was not significant for IORT in pelvis area. • The lack of backscatter due to air in the surgical cavity had a low and localized impact. • Maximal impact of inhomogeneities on dose wa...

• Dosimetric impact of inhomogeneities for IORT in pelvic area was evaluated. • Water non-equivalence of soft tissue was not significant for IORT in pelvis area. • The lack of backscatter due to air in the surgical cavity had a low and localized impact. • Maximal impact of inhomogeneities on dose was obtained in bone tissues (375%). • Bone surface cells were the most exposed part of the bone.
