Figure 5.

Percent depth dose measurements for uniform $10\times 10\hspace{0.17em}{\text{cm}}^2$ field delivery techniques (6 MV photons, 90 cm SSD). Open field defined by MLC; 3.5 cm, 3.0 cm, 3.5 cm strips; 2.0 cm strips; 1.0 cm strips; 1.1 cm dynamic. Measurements were performed with the Attix parallel plate chamber in Solid Water with $14\times 10\hspace{0.17em}{\text{cm}}^2$ jaw settings and are normalized to 10 cm depth. Solid curve is a fit to the open field measurements.
