Table 3 Target volume characteristics

From: Integrated-boost IMRT or 3-D-CRT using FET-PET based auto-contoured target volume delineation for glioblastoma multiforme - a dosimetric comparison

Target volumes PTV1 (= CTV1 *) 12.1 ± 18.6 ccm
  PTV2 175.2 ± 54.4 ccm
PTV1 subvolume number   patient number
