The patient-specific QA have been performed to verify accuracy of MLC movement of IMRT/VMAT technique prior to first day of treatment delivery. Nowadays, the SBRT in lung region is normally performed with VMAT plans especially with flattening filter free option to reduce beam-on time. The purpose of this study was to compare the dosimetric evaluation of lung SBRT plans in patient-specific QA...

**Introduction:** In some radiation therapy protocols, beam modifiers are used to modify the radiation spectrum. Among the most common modifiers are block, wedge filter, flattening filter, multi-leaf collimator and asymmetric jaws. Medical linear accelerators which produce photons with energies higher than 8 MV, impose an unwanted dose to patients due to neutron production. Neutron is...

Introduction: Stereotactic radiosurgery (SRS) is a technique for non-invasive destruction of intracranial tissues or lesion that may be inaccessible or unsuitable for open surgery using ionizing radiation. Initially stereotactic radiosurgery was started with gamma knife unit with Cobalt-60 sources and had circular apertures of 4, 8, 14 and 18 mm[. Subsequently linear accelerator (Linac)...

Purpose: Before a new calculation algorithm can be utilized clinically, a comprehensive evaluation is necessary. The accuracy of the dose calculated is very important for the quality and reliability of radiotherapy planning and delivery. The aim of the this study was to achieve an accurate calculation of dose for small fields(2x2,3x3) large field(7x7,10x10,20x20,25x25,30x30)...
232. Harambee: tuning african brain drain to gain in global radiation oncology using information and communication technology

1. Introduction: The 2014 World Health Organization (WHO) Cancer Report highlights major global cancer disparities, with over 60% of 14 million new cases and 70% of 8.2 million deaths per year occurring in low and middle-income countries (LMIC). These major disparities in cancer deaths are in part a reflection of poignant underlying disparities in Radiation Oncology services. For example,...
293. Africa radiation oncology network (AFRONET): an IAEA pilot telemedicine project for anglophone Africa
Rajiv Prasad (IAEA)
6/22/17, 3:55 PM
BACKGROUND AND CONTEXT In many low income countries, the number of existing radiotherapy centers is insufficient, equipment is often outdated, and there is a dearth of training opportunities for professionals. Many centers work in isolation with limited access to up-to-date published literature, international meetings, and expert opinion. Telemedicine can be used for closing this gap and...
