Figure 7: Homogeneity Index as a function of planning target volume size. (a) for nondetached treatment plans (b) detached treatment plans (c) for pancreas treatment plans (d) intracranial treatment plans. Points that are below the solid line (homogeneity index = 2.0) are defined as being within the radiation therapy oncology group protocol. Triangles mark the Monte Carlo homogeneity indexes; dots mark the finite size pencil beam homogeneity indexes
