  1. Five measurement volumes in the water phantom were compared for the patients with prostate, H&N, esophageal, or rectal cancer, whereas the IC point dose in the cork phantom was compared for the patients with lung cancer. For the use of a 0.6-mL ionization chamber, the standard deviation (SD) of the dose inside the chamber evaluated by Pinnacle is indicated in the last column.
