PTV ratio versus DSC score. Considering a PTV ratio acceptance window of ±10% with respect to the 10 phase benchmark, the FB-Aug scheme meets this criterion for 82% of clinical cases (DSC = 0.774-0.995), as compared to 65% for MIP (DSC = 0.690-0.909), and 41% for AIP (DSC = 0.743–0.913). The FB method faired the least at 34% (DSC = 0.470-0.860). As recommended in previous literature, “good overlap” occurs when DSC > 0.700 [13]
