Abstract

Dose distributions calculated with the fast dose calculator (FDC), a track repeating-algorithm for proton therapy, have been validated versus dose measurements inwater for scanning proton beams at the University of TexasMDAnderson Cancer Center Proton Therapy Center in Houston. The dose calculated with FDC, at the position of the measured points for depth and lateral profiles, was comparedtothe measurements withagamma-index analysis.Itwas found that 99.9% and 99.5% of the measured points hada gamma-index value smaller than unity for the 3%/3 mm and 2%/2 mm dose/distance agreement criteria, respectively.
