Figure 2. Lung. (a) CONV dose plot; (b) SB dose plot; (c) SB-TVL1 dose plot; (d) DVH for rectum; (e) plots of beam-eye view (BEV) dose slices; (f) BEV dose profiles. The dose plot window is [0%, 120%], with 80% isodose line (yellow) and targets (red) highlighted in dose plots.

Conclusion:

A novel SB method is proposed that can generate modulated spatial dose pattern in normal tissues to achieve UTD proton GRID. A treatment planning method with PVDR optimization capability via TVL1 regularization is developed that can jointly optimize PVDR and dose objectives for proton GRID.
