ESTRO’s Physics and Imaging in Radiation Oncology Journal approved for impact factor - PDF Version

Dear Physics Colleagues,

We would like to share with you a major update on the recent progress of the online Journal Physics and Imaging in Radiation Oncology (phiRO) which is published by the European SocieTy for Radiotherapy and Oncology (ESTRO). As you probably know, phiRO has become a well-established, open-access journal that is included in all relevant databases (e.g. PubMedCentral, Scopus and Embase). We have recently been informed that phiRO will receive its first impact factor for 2022 (to be released in June 2023). This achievement represents recognition of more than five years of work to build a high-quality physics and imaging journal that serves the needs of clinical and academic medical physicists in radiation oncology. The profile of phiRO is unique, as it is the only journal that covers physics and imaging research for radiation oncology specifically. 

If you want to know more about phiRO, please browse our recent volumes at either of our two platforms ( and As well as the regular journal, we publish special thematic issues and collections of the highlight papers from the ESTRO conferences. You are also invited to read the editorial from our January 2022 volume, which highlights our first five years of operation (

To submit your next paper to phiRO, please check out our submission system, which is explained at Original research articles in phiRO must be a maximum of 3,000 words in length and may contain up to six tables and/or figures; additional information can be enclosed as supplementary materials. More information on our article formats can be reviewed in our guide for authors:

The editors and editorial board members of phiRO, with our team of high-quality reviewers, are committed to continuing our work for the benefit of physicists and imaging scientists in our field. To strengthen the journal further, we need the support and input of all in our field: authors, whom we ask to submit their strongest papers to us; active scientists, whom we wish to recruit to review submissions critically for us; and readers, whom we hope will continue to use, discuss and cite our publications. We hope that you fall into one or more of these categories. We rely on you to help us so that we in return can help you by making phiRO the first publishing choice for physicists and imaging scientists in radiation oncology. 

Kind regards,
