ΔWET guided plan design. Three PSPT plans (A‐C) were redesigned using field angles that improved upon the ΔWET metrics are compared to the original plan (Original). Between the T0 and T50 dose clouds for both plans, the root mean square deviation (RMSD) was calculated. For both the original and ΔWET plan, the T50 and T0 DVH curves were compared for each plan using ΔAUC analysis
