Materials
A lightweight, portable and water filled phantom was developed in STUK for radiotherapy site vis-its to verify the dose from imaging to delivery, especially for VMAT and IMRT beams, but suits for conventional beams as well. The phantom has been manufactured in STUK mechanical work-shop from PMMA and it is light to transport when empty and easy to fill and set up in hospital....

As a part of an authority control of radiation therapy the doses calculated by hospital dose planning systems for small static fields in...
Introduction
The International Atomic Energy Agency (IAEA) together with the World Health Organization (WHO) have been providing dosimetry audits for radiotherapy facilities primarily in low- and middle-income countries around the world for over 50 years. Until recently, the regular audit service was limited to checking of absorbed dose to water in high energy photon beams in...
Introduction
The practice of radiotherapy includes medical physics activities prior to patient treatments (acceptance and commissioning of medical devices), during the care of each patient (dosimetry planning) and concomitantly with clinical activity (quality control). These activities, which guarantee the quality and effectiveness of the treatment delivered to each patient, are partly or...
