The number of quality assurance computed tomographic scans, the clinical target volumes (CTV) volume and the PTV volume for each patient are also listed. The mean and standard deviation (STD) are calculated for the nominal plan doses.
Bold indicates maximum dose values greater than 110.0%
Abbreviations: Dmax = maximum point dose; NT = normal tissue; pPTV = proton planning target volume; QACT = quality assurance computed tomographic scans.
