Figure 1: (A) The Vero SBRT platform. (B) Right anterior beameye-view of right lower lobe lung SBRT. CTVpet targets (magenta)are shown. Multileaf collimation (green outline) accounts for targetmotion during quiet breathing. Normal tissue contours for theheart (light blue) and esophagus (orange) are depicted to aid beamorientation selection. (C) Axial, coronal, and sagittal projections ofsingle dynamic arc (tan) and six static treatment beams(green=active beam for [B] and blue=other treatment beams inradiation plan). (D) Axial projection of radiation dosimetry byMonte Carlo calculation. The prescription 40 Gy isodose contour isshown in gold, with accompanying isodose contours as labeled.
