Investigation of lung normal tissue doses in lung tumors radiation therapy using both gated and conventional radiotherapy
Introduction: In radiation therapy of lung tumors, respiratory motion causes target moving, so a larger margin is needed to cover the clinical target volume (CTV). With the margin increasing, a larger volume of normal tissue will be exposed to high-dose. In this study, dosimetric parameters of normal lung tissue were compared between gated and conventional radiotherapy (RT), u...
متن کاملEvaluation of Lung Density and Its Dosimetric Impact on Lung Cancer Radiotherapy: A Simulation Study
Background: The dosimetric parameters required in lung cancer radiation therapy are taken from a homogeneous water phantom; however, during treatment, the expected results are being affected because of its inhomogeneity. Therefore, it becomes necessary to quantify these deviations.Objective: The present study has been undertaken to find out inter- and intra- lung density variations and its dosi...
متن کاملOptimization of tangential fields arrangement in the breast cancer 3D conformal radiation therapy
Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...
متن کاملپیش بینی آسیب بافت ریه از طریق بررسی پارامترهای بالینی و دزیمتریکی در بیماران مبتلا به سرطان پستان
Background and purpose: Breast cancer is the most common type of cancer among women. In radiation therapy for breast cancer it is important to prevent damage to normal tissues particularly to lung tissue. In this study, we investigated the incidence of damage in patients with breast cancer by clinical and dosimetric parameters to identify the predictive factors. Materials and methods: An exp...
متن کاملDosimetric Comparison of 3D Tangential Radiotherapy of Post-Lumpectomy Breast at Two Different Energies
Introduction: Radiation therapy following breast conserving surgery is one of the most common procedures performed in any radiation oncology department. A tangential parallel-opposed pair is almost always the technique of choice for this purpose. This technique is often performed based on 3D treatment planning. The aim of this study was to compare 3D treatment planning for two different energie...
