Dosimetric study reveals full three-dimensional modulation maintains target coverage with fewer beam angles in an example case, highlighting its value for complex proton radiotherapy delivery.

Key Points

To describe four proton intensity modulation techniques implemented in a treatment planning system and evaluate their dosimetric efficacy across diverse field combinations.
Implemented four distinct intensity modulation methods into an existing proton treatment planning system.
Applied each technique to an example clinical case using various field numbers and beam configurations.
Evaluated target dose homogeneity and adjacent critical structure sparing via dose-volume histogram analysis.
When using large numbers of beam fields, all four techniques yielded favorable target homogeneity and normal tissue sparing with minimal observable differences.
As the number of beam fields decreased, only full 3D modulation of individual Bragg peaks preserved target coverage while maintaining critical structure sparing.
