Management of a Multi-Room Downtime Event in a Multi-System Environment: A Case Report in Proton Therapy Operations.

ABSTRACT:

Purpose

To describe the management of a 5-day downtime event of a multi-room ProteusPLUS (P-PLUS) proton therapy (PT) system, including the triage and treatment of patients on a single-room ProteusONE (P-ONE) system and 2 linear accelerators.

Methods and materials

Following the failure of a radiofrequency (RF) coupler, patients were triaged for PT on the P-ONE according to medical necessity and available capacity, aiming to minimize the complexity of the P-ONE workload while ensuring each patient received at least 4 fractions of radiotherapy that week. Replanning was required across non-beam matched systems (P-ONE, TrueBeam, and Synergy) and rapidly accomplished primarily via remote planning. Treatment adaptations included extending PT availability from 12 to 19 hours, the s
