Rx – prescribed dose, Pt – point, HR-CTV – high-risk clinical target volume, D90 – minimum dose to the hottest 90% of the target volume, OAR – organ-at-risk, ICRU Pt – point recommended by ICRU report #38 [1], D0.1cc/D2cc – minimum dose to the hottest 0.1 cc or 2 cc of the OAR volume, DICRU – dose to an ICRU Point.
