3D, three-dimensional; PTV, planning target volume; HI, homogeneity index ((D2%-D98%)/D50%); CI, conformity index; PRV, planning organs at risk volume.
*Dmin, minimum dose of the target volume; Dmax, maximum dose of the target volume; Dmean, mean dose of the target volume; D95%, the dose that covers 95% of the target volume.
