Introduction: The functionality and quality of any treatment planning system (TPS) strongly depends on the type of Algorithm which is used by it. Obviously, the role of dose distribution algorithms in calculation of prescribed dose inside the tumor in modern radiotherapy techniques has more important than past to achieve the best clinical outcomes, especially in tumors which ar...

Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...

The Spray Treatment Planner is an intelligent decision support system for productivity and efficiency evaluation in an aerial spray treatment project. It can be used as a tool to plan the schedule for spraying pesticides aerially. STP schedules the spraying operation of selected blocks from selected airports using single or multiple aircraft(s). The scheduling is done to maximize the spray effi...

Introduction: Radiotherapy is an effective modality to treat esophageal carcinoma. Due to various inhomogenous tissues with a variety of physical and radiological properties which can cause uncertainty in accurate dose calculations in radiation therapy, accuracy of TPS is very important. The aim of this study was to quantify dose calculation accuracy of CoreplanTM TPS in an inh...

Background: We have validated the monitor unit calculations from a commercially available treatment planning system (TPS) for three intensity modulated radiotherapy (IMRT) planning techniques for tangential breast irradiation by using ionization chamber measurements. Materials and Methods: Treatment plans were generated for forty-two breast patients by a forward planned field in field ...
