Verification of delivered dose to the Lips carcinoma tumors with HDR brachytherapy sources: 192Ir and 60CO in an exclusive plexiglass Phantom.
Introduction: Brachytherapy, especially using manually after loaded Iridium-192 and Cobalt-60, can be applied as a sole treatment, as a treatment complementary to surgery, and as a local boost in combination with EBRT. The use of HDR brachytherapy catheters incorporated in removable dental molds allows repeated, highly reproducible, fractionated outpatient brachytherapy of supe...
متن کاملQuality assurance prusedore in high dose rate bracythrapy
Introduction: Quality assurance is essential for obtaining the best achievable tumor control, avoiding unnecessary side effects, accuracy and safety during performing High Dose Rate (HDR) Brachytherapy (BT). Quality assurance is extremely important because HDR BT procedures are performed quickly, with high doses given in a short time period, with little opportunity for correcti...
متن کاملIndependent assessment of source transit time for the BEBIG SagiNova® high dose rate brachytherapy afterloader
Introduction: The dwell time and transit time components contribute to the overall delivered dose to patients in high dose rate (HDR) brachytherapy treatments. The transit time results from source entry and exit as well as source movements between dwell positions. It depends on various parameters such as the source speed profile, source indexer distance to dwell position, and ...
متن کاملConsideration of accurate dose distribution for Contura balloon catheter in breast brachytherapy with MCNP5 simulation
Introduction: Contura is a balloon applicator that used to deliver intra cavity radiation for Partial Breast Irradiation (PBI) treatments. Contura with 4 peripheral lumens surrounding the central, for loading HDR sources from an after loader system can provide an asymmetric dose distribution and gives a more flexible shape of dose than earlier balloon applicators such as Mammo...
متن کاملEvaluation of dose distribution and dose gradient in brachytherapy cylindrical applicators using a dedicated Phantom for Iridium-192 and Cobalt-60 HDR sources
Introduction: A study was performed to evaluate radiation dose distribution and dose gradient around cylindrical applicators for high-dose-rate (HDR) brachytherapy systems with 192Ir, 60Co brachytherapy source applied for rectal and vaginal cancers treatments. Materials and Methods: Two additional computed tomography (CT) based plans were generated using a ...
