Retrospective analysis of reduced energy switching and room switching times on throughput efficiency of a multi-room proton therapy center.
A 4-room center treating ~90 patients/day, treating for ~7 years underwent a software upgrade which reduced room and energy switching times from ~30 to~20 sec and ~4 sec to ~0.5 sec respectively, this study by ProCure NJ and MSKCC compared patient volumes in two 4 month periods before and after the software change.
This study found that for bilateral head and neck and prostate patients, the beam waiting time was reduced by nearly a factor of 3 and the beam delivery times were reduced by nearly a factor of 2.5, and the gantry capacity has increased from approximately 30 patients to 40-45 patients in a 16 h daily operation.
