In the plan above, there are three treatment fields: AP, PA, and right lateral. The target volume (GTV) is in red. With just this equally weighted three beam arrangement, a likely wedge arrangement will be:

a) Wedges in the AP & PA, thick end to the lateral side
b) Wedges in the AP & PA, thick end to the medial side
c) Wedge in the lateral, thick end to the anterior
d) Wedge in the lateral, thick end to the posterior
