Objective: To study the dosimetric importance of Jaw tracking technique in reducing the doses to organs at risk (OAR) while achieving the optimal dose coverage for the target.
Methods: We retrospectively selected ten Glioblastoma cases and for each patient, two plans were created namely Static Jaw Technique Dynamic Intensity Modulated Radiotherapy plan and Jaw Tracking Technique D-IMRT plan with 6 MV for Varian Truebeam™ STx machine using Eclipse Treatment planning system. Both plans were analyzed and compared based on various dosimetric parameters for Planning Target Volume (PTV) and OARs.

Background: The purpose of this study is to show the dosimetric importance of using daily image guidance in radiotherapy treatment.
Methods: A sample of 30 patients with various head and neck cancers were retrospectively selected for the studies. The prescribed dose, 66 Gy/33 fractions was used for all patients who received 7 to 9 beams, 6 MV Intensity Modulated Radiation Therapy (IMRT) plan delivered by Varian Truebeam STx.
Purpose: The present study aims to compare different dosimetric parameters from field sizes defined by secondary and tertiary collimators. A comparison has been drawn between two types of Multi Leaf Collimator (MLC) designs.
Materials And Methods: The measurements were obtained using Millennium MLC (Mi-MLC) from Varian Unique™ linear accelerator (LINAC-1) and compared with measurements from Varian Truebeam™ linear accelerator (LINAC-2) using High Definition MLC (HD-MLC).
