    “…Parameters of implant quality analyzed included ability to insert tandem, ratio of needles loaded to the number of needles inserted, and incidence of uterine or organ at risk (OARs) perforation. Dosimetric parameters evaluated were dose to point A*, TRAK, D(90) high-risk clinical target volume (HR-CTV), and D(2cc) to OARs (bladder, rectum, and sigmoid). …”

    “…The D2cc parameter allowed the evaluation of the dose received by the OARs. For the rectum, a dose reduction of 9.67% (range 0.29–32.86) was obtained with the second geometry of implantation compared to 10.14% (range 1.43–28.33) with the third geometry. …”

    “…The Tukey test and one-way analysis of variance were used to compare the target coverage and doses to organs at risk (OARs) of the three techniques. RESULTS: For target coverage, the VMAT-only and modified hybrid plans showed comparable target coverage in terms of D(mean) (50.33 Gy vs. 50.53 Gy, p = 0.106). …”

    “…PURPOSE: Fast and accurate outlining of the organs at risk (OARs) and high-risk clinical tumor volume (HRCTV) is especially important in high-dose-rate brachytherapy due to the highly time-intensive online treatment planning process and the high dose gradient around the HRCTV. …”
