Pt. = patient, No. = number; PTV = planning target volume; Vol. = Volume (cc); Dmin = minimum dose; EQD2 = biologically equivalent dose for 2Gy fractionation; D1cc = Dose (Gy) to 1 cc oft the organ wall(bladder, rectum, sigmoid); D2cc = Dose (Gy) to 2 cc of the organ wall; Vref. = volume (cc, of a organ at risk) covered by the reference dose (30 Gy); COIN = Conformal Index.
