Pre-treatment 2D Scout Verification Tolerances and Dosimetry Effects on OARs for the Cylinder High Dose Rate Brachytherapy Treatment of Vaginal Cuff Cancer
Purposes: to statistically find out the achievable and practical pre-treatment verification tolerances for HDR (high dose rate) cylinder treatment using scout AP (anterior and posterior) /LAT (lateral) images and the corresponding organs at risk dosimetry effects. Materials and Methods: Five previously treated vaginal cuff cancer patients were randomly selected. All of the patients had prescrip...
متن کاملEffects of vaginal cylinder position on dose distribution in patients with endometrial carcinoma in treatment of vaginal cuff brachytherapy
PURPOSE To investigate the impact of different cylinder positions on dosimetry of critical structures in patients with endometrial carcinoma undergoing three-dimensional image-based vaginal cuff brachytherapy (VCB). MATERIAL AND METHODS We delivered VCB at a dose of 4 Gy to a depth of 5 mm in the vaginal cuff of 15 patients using three different cylinder positions (neutral [N], parallel [P], ...
متن کاملVaginal cuff brachytherapy in endometrial cancer – a technically easy treatment?
Endometrial cancer (EC) is one of the most common gynecological cancers among women in the developed countries. Vaginal cuff is the main location of relapses after a curative surgical procedure and postoperative radiation therapy have proven to diminish it. Nevertheless, these results have not translated into better survival results. The preeminent place of vaginal cuff brachytherapy (VCB) in t...
متن کاملinvestigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Single versus multichannel applicator in high-dose-rate vaginal brachytherapy optimized by inverse treatment planning
PURPOSE To retrospectively compare the potential dosimetric advantages of a multichannel vaginal applicator vs. a single channel one in intracavitary vaginal high-dose-rate (HDR) brachytherapy after hysterectomy, and evaluate the dosimetric advantage of fractional re-planning. MATERIAL AND METHODS We randomly selected 12 patients with endometrial carcinoma, who received adjuvant vaginal cuff ...
