Multivariate log file analysis for multi-leaf collimator failure prediction in radiotherapy delivery
Publikováno v:
Physics and Imaging in Radiation Oncology, Vol 15, Iss , Pp 72-76 (2020)
Background and Purpose: Motor failure in multi-leaf collimators (MLC) is a common reason for unscheduled accelerator maintenance, disrupting the workflow of a radiotherapy treatment centre. Predicting MLC replacement needs ahead of time would allow f
