Single versus multichannel applicator in high-dose-rate vaginal brachytherapy optimized by inverse treatment planning.
Yasir A. Bahadur,C. Constantinescu,Ashraf H. Hassouna,Maha M. Eltaher,Noor M. Ghassal,Nesreen A. Awad +5 more
TL;DR: Vaginal HDR brachytherapy using a multichannel vaginal applicator and inverse planning provides dosimetric advantages over single channel cylinder, by reducing the dose to organs at risk without compromising the target volume coverage, but at the expense of an increased vaginal mucosa dose.

Three-dimension anatomy-based planning optimization for high dose rate vaginal vault brachytherapy.
Yasir A. Bahadur,Ashraf H. Hassouna,C. Constantinescu,Adly F. Naga,Noor M. Ghasal,Mohamed E El-Sayed +5 more
TL;DR: Three-dimension inverse planning provides the ability to balance the target dose coverage against the sparing of organs at risk in vaginal vault high-dose-rate brachytherapy, and is retrospective compared with conventional planning methods.

Independent assessment of source transit time for the BEBIG SagiNova® cobalt-60 high dose rate brachytherapy afterloader.
TL;DR: The results show that currently SagiNova® afterloader does not apply transit time compensation and suggest a 0.2–0.5 s compensation for each arrival and departure DP from/to the afterloader, depending on position in an 11 cm active length.

Design and Development of In-House Multichannel Applicator for HDR Vaginal Brachytherapy and Dosimetric Comparision with Single Channel Applicator.
TL;DR: In house multichannel applicator with 3D inverse treatment planning techniques improves the dosimetric advantage over single channel applicators for endometrial cancer patients.

Incorporating Treatment Time into Butterfly Optimization to Reduce Total Treatment Time for Vaginal Cylinder Brachytherapy
TL;DR: Dose optimizations based on the BOA algorithm yield closer dose conformity in vaginal HDR treatment than AVOA, and incorporating total treatment time into the optimization algorithm reduces the delivery time while having only a small effect on dose conformity.

Impact of "optimized" treatment planning for tandem and ring, and tandem and ovoids, using high dose rate brachytherapy for cervical cancer.

TL;DR: Doses given in high dose rate intracavitary brachytherapy border on tissue tolerance, and Optimization of a tandem and ovoids best ensures that the doses are not diminished at the treatment sites, and that the potential for overdose is reduced.

Optimized Dose Distribution of a High Dose Rate Vaginal Cylinder
TL;DR: Dose calculation models available in a computer treatment-planning system must be evaluated carefully to ensure their correct application when optimized dose distribution at a distance from the cylinder surface is calculated using an accurate dose calculation model, the vaginal mucosa dose becomes significantly higher, and therefore should be carefully monitored.
Journal ArticleDOI
Comparison of high dose-rate and low dose-rate dose distributions for vaginal cylinders.
TL;DR: The comparison between traditional low dose- rate distributions and high dose-rate distributions shows that, unlike the low doses, a relatively uniform high doses distribution can be obtained independent of cylinder diameter.

Optimization in high dose rate brachytherapy for utero-vaginal applications
TL;DR: Modern brachytherapy techniques enable the individualization of treatments by optimization procedures by changing some parameters of the treatment by modifying dwell times and dwell positions of the uterine and vaginal sources.

Comparison of traditional low-dose-rate to optimized and nonoptimized high-dose-rate tandem and ovoid dosimetry
TL;DR: Optimize HDR allows specification of dose to points of interest, can approximate LDR dosimetry, and appears superior to nonoptimized HDR treatment planning, at least at the tandem tip.
