The dependency of beam‐on‐time efficiency on respiration period and layer switching time for respiratory gating proton therapy of liver cancer
This study presents two key strategies for reducing total treatment time: (1) for the proton therapy machine with very short T<sub>LS</sub>, BoT efficiency is less of a concern; and (2) for machines with a T<sub>LS</sub> of around 2 s, optimal BoT efficiency is achieved with a respiration period between 2.5 and 3 s. It is important to note that the exact optimal value may vary depending on patient-specific factors such as target size.
