In parallel with textbook length reports and codes of practice, IPEM has launched a complementary series of short topical reports to be published in its Journal Physics in Medicine and Biology (PMB). These aim to address a specific area of current or developing practice, with rapid production times, to benefit the clinical physicist or engineer 'at the coalface'. The first topical report was published in PMB in November 2016 and covers the use of flattening-filter free (FFF) beams in radiotherapy.
PMB welcomes the opportunity to publish IPEM codes of practice and topical reports, subject to the usual rigorous peer-review process and given the global reach of the journal, the requirement that the international context is addressed. We believe these publications will be of broad benefit to medical physics and bioengineering practitioners who strive to deliver the highest quality healthcare to patients.

IPEM Topical Report An international IPEM survey of MRI use for external beam radiotherapy treatment planning
Despite growing interest in magnetic resonance imaging (MRI), integration in external beam radiotherapy (EBRT) treatment planning uptake varies globally. In order to understand the current international landscape of MRI in EBRT a survey has been performed in 11 countries. This work reports on differences and common themes identified.
IPEM Topical Report Guidance on the use of MRI for external beam radiotherapy treatment planning
This document gives guidance for multidisciplinary teams within institutions setting up and using an MRI-guided radiotherapy (RT) treatment planning service. Next, practical guidance is given on the following, in the context of RT planning: training and education for all staff working in and around an MR scanner; RT patient set-up on an MR scanner; MRI sequence optimisation for RT purposes; commissioning and quality assurance (QA) to be performed on an MR scanner; and MRI to CT registration, including commissioning and QA.

IPEM Topical Report Current molecular radiotherapy service provision and guidance on the implications of setting up a dosimetry service
The aims of this report were to assess the main reasons why centres are not performing MRT dosimetry and provide advice on the resources required to set-up such a service. A survey based in the United Kingdom was developed to establish how many centres provide an MRT dosimetry service and the main reasons why it is not commonly performed.

IPEM Topical Report An evidence and risk assessment based analysis of the efficacy of quality assurance tests on fluoroscopy units—part II; image quality
This work aims to assess the efficacy of x-ray quality assurance tests undertaken on fluoroscopy units in the UK. Information was gathered on the results of image quality tests recommended by the reports of the Institute of Physics and Engineering in Medicine, and those additionally undertaken by medical physics departments.

IPEM Code of Practice for high-energy photon therapy dosimetry based on the NPL absorbed dose calibration service
This updated COP recommends the irradiation geometries, the choice of ionisation chambers, appropriate correction factors and the derivation of absorbed dose to water calibration coefficients, for carrying out reference dosimetry measurements on MV external beam radiotherapy machines. It also includes worked examples of application to different conditions.

IPEM Topical Report A 2018 IPEM survey of MRI use for external beam radiotherapy treatment planning in the UK
With a view to developing consensus guidelines for the use of MRI in external beam radiotherapy (EBRT) treatment planning in the UK, a survey was undertaken by an IPEM working-party to assess the current landscape of MRI use in EBRT in the UK.

IPEM Topical Report Personal dose monitoring requirement in healthcare
There are two major challenges for personal dosimetry in healthcare. The implications for interventional clinicians of the reduction in eye dose limit in the European Basic Safety Standards and UK regulations, and the large dose gradients across the hands of nuclear medicine staff who manipulate radionuclides. Guidelines on personal dosimetry have been prepared to address these and other issues.

IPEM Topical Report An evidence and risk assessment based analysis of the efficacy of tube and generator quality assurance tests on general x-ray units
This work aims to assess the efficacy of current x-ray quality assurance (QA) testing regimes on tube and generator systems for general radiographic usage in the UK.

IPEM Topical Report Guidance on implementing flattening filter free (FFF) radiotherapy
Flattening filter free (FFF) beams are now commonly available with new standard linear accelerators. The purpose of this report is to provide practical implementation advice and references for centres implementing FFF beams clinically. In particular UK-specific guidance is given for reference dosimetry and radiation protection.
