Table 2.

Comparison of the results between dose distributions from original PBC‐ and AAA‐based plans, which were recalculated with the AXB algorithm. All DVH parameter results represent the difference values between the original AAA‐calculated plan and the AXB‐recalculated AAA plan or the original PBC‐calculated plan and AXB‐recalculated PBC plan. Absolute dose values for various DVH parameters from different plans are normalized to the prescribed dose values
