Figure 6.
The longitudinally averaged dose to points on the surface of the MCVC applicator for the air‐in‐grooves set‐up with the central channel loaded (a), the water‐in‐grooves set‐up with the central channel loaded (b), the air‐in‐grooves set‐up with the peripheral channels loaded (c), and the water‐in‐grooves set‐up with the peripheral channels loaded (d). The dose was calculated by TG‐43, sACE, and hACE using the same dwell times corresponding to a dose of 500 cGy (TG‐43) specified to the surface of the applicator. Data points at 0° and 180° are above the two outer grooves on the surface of the applicator. The red line indicates the specified dose of 500 cGy (Rx). The longitudinally averaged dose measured by radiochromic film on the surface of the MCVC applicator is also plotted.
