ESTRO 35 2016 _____________________________________________________________________________________________________ original GTV when contouring the GTV on the anatomy of the second CT scan.SIB created two plans. One is 1st CT / 1st Plan and the other is SIB sum (25 fractions (deformed CT) and 5 fractions ( 2nd CT )) . A deformed CT (dCT) with structures was created by deforming the 1st CT to the 2nd CT. We summed up dose used in 1st Plan and 2nd Plan using a commercially software ( MIM Maestro 6.3 ). The two types of plans were compared with respect to DVHs for other dosimetric parameters of the PTVboost, PTVel, brainstem, spinal cord and parotid gland.

Introduction: Presence of dental filling material (DFM) such as amalgam in treatment patient with nasopharyngeal cancer (NPC) is common. Streaking artifact Arising from this high density material in computed tomography (scan), may lead to perturbation in dose calculation and dose delivery. Widespread performance of intensity-modulated radiotherapy (IMRT) for NPC using anterior...
متن کاملThe Relationship between the Different Prostate Intensity Modulated Radiation Therapy Techniques and Patient’s Anatomical Parameters
Introduction: Intensity Modulated Radiotherapy (IMRT) is a common method for treating prostate cancers. Different IMRT methods can apply for irradiating the prostate, but there is not clear that which of these methods can provide better dose distribution for each patient individually. Therefore, the aim of this study was to evaluate the relationship between the different prosta...

PURPOSE Intensity-modulated radiation therapy (IMRT) is the most common treatment technique for nasopharyngeal carcinoma (NPC). Physical quantities such as dose/dose-volume parameters are used conventionally for IMRT optimization. The use of biological related models has been proposed and can be a new trend. This work was to assess the performance of the biologically based IMRT optimization mod...
متن کاملActual Anatomical and Dosimetric Changes of Parotid Glands in Nasopharyngeal Carcinoma Patients during Intensity Modulated Radiation Therapy
The goal of this study was to evaluate the actual anatomical and dosimetric changes of parotid glands in nasopharyngeal carcinoma patients during intensity modulated radiation therapy. With helical tomotherapy, its planning system, and adaptive software, weekly anatomical and dosimetric changes of parotid glands in 35 NPC patients were evaluated. Interweekly parotid volume varied significantly ...
