Physics - Dose calculation algorithms

ESTRO 2024

With respect to the target and OAR dose comparisons, in every case the differences in dose metrics were significantly different (P-values <0.001-0.28) between AAA/MC and AXB/MC with AXB having the superior agreement with MC. The mean differences and specific p-values between MC for both algorithms were lower in each case for AXB, and this data can be found in Table 1.

Conclusion:

In this study we evaluated the accuracy of two common dose calculation algorithms in SBRT for ventricular tachycardia through comparison with Monte Carlo simulation. By every metric evaluated, including target dose coverage, OAR dose endpoints, and 3D gamma dose evaluation, AXB is the more accurate and appropriate dose calculation algorithm to use in this setting.
