The course is designed to provide the necessary practical and theoretical background in medical physics. The first course of the series covers the radiotherapy physics service of image guided and intensity modulated radiotherapy (IG-IMRT) focusing on the quality assurance aspect. The sessions include practical aspects on quality assurance practice for IM-IGRT including IGRT image quality and IMRT dosimetry verification. The course is aimed primarily at radiotherapy physicists, but should also benefit postgraduate students, researchers, engineers, radiographers, manufacturer’s representative and anyone interested to update their knowledge and understanding of IG-IMRT.
