Figure 2: Example dose distributions for the clinical plan (CLP) and knowledge-based plans using the TrueBeam and Halcyon in open-loop validation (KBPopen-TB and KBPopen-Hal). Compared with the clinical plans, both the KBPopen-TB and KBPopen-Hal had more extended low-dose distribution but higher conformity to the planning target volume
