TABLE V.

Average AUC for each device, irrespective of analysis method. The thick line indicates where the devices were grouped into significantly better and worse performing groups based on AUC. The AUC listed in this table is an average of the AUCs from all three gamma analyses (2%/2 mm, 3%/3 mm, and 5%/3 mm) for the planar/array dosimeters, as well as both snc and DoseLab software packages for the MapCheck measurements.

Cc04 ion chamber	0.94
AP composite MapCheck	0.85
ArcCheck	0.84
EDR2 film	0.82
AP field-by-field MapCheck	0.66
Planned angle MapCheck	0.65
