Comprehensive beam delivery latency evaluation for gated proton therapy system using customized multi-channel signal acquisition platform

CONCLUSION: With the developed multi-channel signal acquisition platform, it was able to investigate the gating lags happened in both the respiratory gating system and the proton treatment system. The resolution of the platform is enough to distinguish the delays at the millisecond time level. Both the respiratory gating system and the proton treatment system made contributions to gating latency. Both systems contributed nearly equally to the total beam ON latency, with approximately 100 ms. In contrast, the respiratory gating system was the dominant contributor to the total beam OFF latency.PMID:38551392 | DOI:10.1002/acm2.14349
