Abstract

In this study, the quality assurance of the linear accelerator available at the Baghdad Center for Radiation Therapy and Nuclear Medicine was verified using Star Track and Perspex. The study was established from August to December 2018. This study showed that there was an acceptable variation in the dose output of the linear accelerator. This variation was ±2% and it was within the permissible range according to the recommendations of the manufacturer of the accelerator (Elkta).

Highlights

The principle of radiation therapy depends on using high energy ionizing radiations in the patient’s treatment especially those have had malignant tumors
The external dose was measured from the linear accelerator for 6MV and 10MV
The results shows that the dose measured by star Track and Perspex is agree between the device, where we note that the dose out of the Star Track real and effective and stable readings rate change within the range of ±2 [8]

Summary

Introduction

The principle of radiation therapy depends on using high energy ionizing radiations in the patient’s treatment especially those have had malignant tumors. Main object of radiation therapy is to give a sufficiently high absorbed dose to define the target volume in order to eradicate the tumor with minimum dose as possible to the healthy tissues [1]. For this reason, it is necessary to highly conform the treatment beam to the target treatment and to minimize the radiation dose to the normal tissues surrounding the tumor [2, 3]. The aim of this study is to check the quality assurance of the linear accelerator in Baghdad Center for Radiation Therapy and Nuclear Medicine using Star Track and Perspex.
