[ 1 ] - A Specific Patient Quality Assurance (PSQA) procedure for a Co-60 source based High Dose Rate Brachytherapy
Introduction: In radiation therapy, accurate dose determination and precise dose delivery to the tumor are directly associated with better treatment outcomes in terms of higher tumor control and lower post radiation therapy complications. The current study aims the development and clinical application of the Patient Specific Quality Assurance (PSQA) procedures for nasopharyngea...
[ 2 ] - Localization of electron virtual SSD in a Siemens-Primus linear accelerator: Comparison of measurements with Monte Carlo simulation
Introduction: Because of importance of impact of the Source to Surface Distance (SSD) in determining of monitor unit for electron-therapy, it is essential to know the Virtual Source Position (VSP) for electron beam for a linear therapeutic accelerator for each energy and field size. , especially using the Khan method (photo distance squared method) And compare the results with...
[ 3 ] - Evaluating variation of Hot Spot Location in order to radiobiological calculation of Organ at Risk in High-dose- rate Brachytherapy of Cervical Cancer
Introduction: Gynecological malignancies present challenges in determining an appropriate volumetric dose due to the highly variable physiologic activity of the surrounding tissue. Because of the high doses used in brachytherapy, surrounding structures have the potential to move around in the dose region and receive unknown amounts of radiation. Calculating hotspot region from ...
[ 4 ] - 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...
