For standard TG43 dose calculation, applicators were manually digitized on the planning images, while for AcurosBV calculations, solid renderings of Titanium Fletcher Suite Delclos (FSD) applicators included in BrachyVision were matched to those used clinically and Ti needles were manually digitized. The dose was recalculated using Varian's AcurosBV 13.5 and dose\u2010to\u2010medium\u2010in\u2010medium (D<jats:sub>m,m<\/jats:sub>) was reported. EQD2 values for targets and organs at risk were compared between dose calculation formalisms. D<jats:sub>90%<\/jats:sub> and D<jats:sub>98%<\/jats:sub> values were reported for the high and intermediate\u2010risk CTVs, and  values were reported for OARs including bladder, rectum, sigmoid, bowel, and vagina. Due to variability within the patient cohort, the dosimetric impact of AcurosBV was investigated corresponding to planning image modality (CT vs. CBCT), presence of Ti needles, and contrast within vaginal balloons used to stabilize implants. AcurosBV showed lower dosimetric values for all plans compared to TG43.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average\u00a0\u00b1\u00a0standard deviation of dosimetric reduction in D<jats:sub>90%<\/jats:sub> was 4.33\u00a0\u00b1\u00a00.09% for CTV<jats:sub>HR<\/jats:sub> and 4.12\u00a0\u00b1\u00a00.09% for CTV<jats:sub>IR<\/jats:sub>.
