The Second Edition of QUATRO guidelines on “Comprehensive Audits of Radiotherapy Practices: A Tool for Quality Improvement” is now available on the IAEA website. This edition provides revisions of the QUATRO guidelines published in 2007, by incorporating new procedures relevant to newer technologies and modalities that have become routinely used in radiotherapy centres in the interim period. The guidelines are endorsed by the European Federation of Organisations for Medical Physics (EFOMP), the European Society for Radiotherapy and Oncology (ESTRO), and the International Organization for Medical Physics (IOMP).
