Nanodosimetry-Based Plan Optimization for Particle Therapy
Figure 7
Nanodsimetric quantities calculated for the optimized two-field proton plans as a function of the voxel depth. Results of the uniform optimization and uniform cluster yield optimization are shown in the left and right columns, respectively. (a), (b) Composite . (c), (d) Composite (squares) and (triangles). (e) Frequency of small clusters (squares) and large clusters, (triangles) relative to the total yield . (f) composite .
