Figure 1.
The arc arrangement and the example of the beam's eye view (BEV) for the dynamic conformal arc plans. Frontal views of the three-arc plan (a) and five-arc plan (b) reveal the table position, and the superior view of the five-arc plan (c) denotes the arc length. The BEV (d) from the arc with a table position of 90° in the plan for planning target volume of 15.66 cm3 demonstrated the aperture of the micro-multileaf collimator that changed for each 10° interval along with the altered projection of the orientation figures displayed at the left lower corners.
