Background: Intensity Modulated Radiotherapy (IMRT) can improve radiotherapy (RT) results by improving healthy tissue sparing. Additionally, IMRT provides more consistent dose deliveries and suppresses secondary tumor formation. RT is a principal treatment in breast cancer (BC). Aim: To evaluate the outcome of the Radiotherapy Plans (RTP) that use IMRT technique to left breast and other organs,...

Intensity Modulated Radiation Therapy (IMRT) is an innovative, three-dimensional conformal radiation treatment that can deliver highly focused and precisely shaped radiation to a tumor site through the use of the Multi-Leaf Collimators (MLC). A crucial step in IMRT procedure is the verification of MLC positioning to assure the accuracy of radiation treatment delivery. In this paper, we have dev...

Introduction: Whole breast radiotherapy after breast-conserving surgery decrease the risk of local recurrence. this study investigates the dosimetric aspects of intensity modulated radiotherapy (IMRT) compared to conventional tangential wedge-based beams techniques (CTT) of the whole breast in early stages breast cancer patients.   Materials and Methods: Co...

An overview of Intensity Modulated Radiation Therapy (IMRT), a true revolution in the field of radiation oncology in that it provides the unprecedented means of conforming to the shape of the target tissues in 3-dimensions, reducing the risk of complications thereby improving the quality of life of irradiated patients. Moreover, IMRT provides the means to deliver higher than conventional doses ...

INTRODUCTION Inverse-planned intensity modulated radiation therapy (IP-IMRT) has potential benefits over other techniques for tangential intact breast radiotherapy. Possible benefits include increased homogeneity, faster planning time, less inter-planner variability and lower doses to organs at risk (OAR). We therefore conducted a pilot study of previously treated intact breast patients to comp...

The additional intensity modulated radiation therapy (IMRT) and total body irradiation (TBI) to conventional treatment clinical treatment procedures can significantly increase the contribution of accelerator head leakage radiation. Previously recommended procedures by the National Council on Radiation Protection and Measurements (NCRP) for vault design, specifically calculations of primary and ...

Objective: To carry out dosimetric comparison between volumetric modulated arc therapy (VMAT) and intensity-modulated radiation (IMRT) in cervical cancer. Methods: 50 postoperative cancer patients were included this study. The admitted for treatment from January 2021 to 2022. VMAT IMRT plans designed each patient analyze the dose distribution target area of two techniques. Results: Comparing mo...

This paper considers the problem of radiation therapy treatment planning for cancer patients. During radiation therapy, beams of radiation pass through a patient. This radiation kills both cancerous and normal cells, so the radiation therapy must be carefully planned to deliver a clinically prescribed dose to certain targets while sparing nearby organs and tissues. Currently, a technique called...
