TABLE II.
Information on the complexity of the 24 IMRT plans investigated. The number of segments per field (average and range across all fields in the plan), whether the plan involved a carriage split, and the total number of fields are shown. Additionally, the last column shows how the plans were sorted based on the gold standard.
