Comparison of mean target dose coverage between the original plan on 5 daily fraction magnetic resonance imaging scans (predicted) and after reoptimization (reoptimized). (a) Planning target volume (PTV) V95%, (b) optimized PTV (PTVopt) V95%, (c) PTVopt D99%, (d) frequency of PTV V95% >90%, (e) frequency of PTVopt V95% >90%, and (f) frequency of PTVopt D99% >20 Gy. Red line denotes the median, and the edges of the box are the 25th and 75th percentiles; the whiskers extend over mean ± 2.7 × standard deviation, and open circles denote each of the 20 oligometastases cases analyzed.
