Abstract
The dose rate of voxels within a particle beam (e.g., proton beam) treatment field delivered using pencil beam scanning (PBS) is calculated, and a representative dose rate for the particle beam treatment field is reported. The calculations account for a dose accumulation in a local region or a sub-volume (e.g., a voxel) as a function of time.
