PRESIDENT'S FOREWORD
FOR THE YEAR ENDED 31 DECEMBER 2023
IPEM'S mlssion is to improve health through physics and en8ineering in medicine. As an organisation our aim is to
facilitate members as a community of professionals and volunteer5. Their work through IPEM shapes professlonal
development and practice development, delivering value directly to the public in the form of professionalism, knowledge
and innovation.
IPEM'S Story in 2023 15 about growth and focus. Over the year, decisions taken by successive Boards of Trustees since
2020, to focus on hi8h value artivities closely aligned to core purpose. begin io influence IPEM'S income. The Strategy set
out in "IPEM 2025"
which was adopted in 2021 with the primary alm of reducing our dependence on income from
journals. concentrated staff activity on three areas - professional development. community and leadership. These were
supported by six operational plans and stretchin8 targets for 2023 were agreed. The capacity and capability of the staff
body was improved through recruitment and by Ihe final quarter of ihe year it became evldent that IPEM'S customer base
and income were showing signs of improvement.
Professional development Wa5 key to our growth. A5 well as three new tralnlng courses, the new Cllnlcal Scientist Guided
Trainin8 Scheme was launched in 2023 and 5ucce55fully enrolled two cohort5 of students. The arcreditation committee
had an exceptionally busy year with new Msc and short courses approved. IPEM hosted 18 events in 2023, five more than
the previous year, wlth the number of delegates Sncreasin8 from lust under Iofyj to more than 1300,
Although IPEM'S membershlp fell mar8inally in 2023, the year saw renewed efforts to speed the growth on the Fellowship
8rade. though improved communicatlon and streamllned processes, wlth 9 new Fellows created.
IPEM continued to develop our approach to diversity and inclusion. In 2023 we changed the emphasis from equality to
equity. in Ilne with Sclence Council's recommendations. We continued to work wSth, Share Ideas and learn from a ran8e of
stakeholders in this important area of our development as an or8anisation.
IPEM'S leadershlp flourlshed. We spent more tlme focuslng on public pollcy and advocacy, which Is an area our members
said Should be among our top priorities. IPEM'S 'Science Leadership strate￿ work grew in the year, lead by Jen Cannon.
A volunteer day wès held In September, in which the grand challenge5 and emer8ing trend5 that are shaping the future
operatin8 environment for IPEM members were further developed. The subjects that make up the strategy are
Increasingly the focus of our resources and guldance, along with the ideas that our members generate in other areas of
science and en8ineerin8.
2023 wa5 an incredibly busy year for our volunteer5. especially for th05e involved in course accredltation and a55e55ment.
which grew considerably. Across the organisation, volunteers donate their time and best efforts to support the profession.
Without this considerable resource, IPEM'S strategy would face impossible limitations. Althou8h I have served as
volunteer for manv vears myself. I have been surprised and impressed at every turn by quite how much IPEM'S volunteers
have achieved in my first 12 months as President.
IPEM's Staff group grew in the year, with new roles added. It was sad to see the retirement of Marie Goodall. after 37
year5.

PRESIDENT'S FOREWORD {CONTINUED)
FOR ThfE YEAR ENDED 31 DECEMBER 2023
Ovefall, 2023 was an important year for IPEM. The growth in our income of £230,000, which was delivered by growth in
resources and expenditure. provided proof of concept that with a focused strategy, driven by risk and performance, there
are opportunities for IPEM to grow towaid5 a mole sustainable lon8.term financial p051tion. Thls Is particularly true in
profe55i0nal development, and our plans include considerable further investment in this area. Members told they wanted
IPEM to provide advocacy, resources and traininE, and I believe we made advantes in each of these in 2023. IPEM 2025.
our strategy* has given us direction based on professional development, community and leadership. Towards the end of
2023. 1 am very pleased to say that the Board agreed to long.term plans which wlll See us build on and extend this
approach towards 2030. These plans will be published In 2024 and I look forward to workln8 Wlth members and
volunteers to bring them about.

the trustees were not entltled to prepare the flnancial statements in accordance with the small companles, regime
and take advantage of the small companies, exemptions in preparing the directors, report and from the requirement

ResponsibllhSes of trustees
As explalned more fully in the trustees. responsibilities Statement. the trustees Iwho are also the dlrectors of the parent
charitable company for the purposes of company lawl are responsible for the preparation of the financial statements and
for bein8 satisfied that they 8ive a true and fair view, and for such internal control as the trustees determine is nece55ary
to enable the preparation of financial statements that are free from material misstatement. whether due to fraud or

considered material if, individually or in the aggregate, they could reasonably be experted to influence the economic
decisbons of users taken on the basls of these flnanclal statements.
Irregularities. including fraud. are instances of non-compliance with laws and regulations. We design procedures in line
with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The
extent to which our procedure5 are capable of detectin8 irre8ularitie5, includin8 Iraud is detailed below..
Our approach to identifying and assessing the rlsks of materSal mi5Statement in respect of irre8sJlarities. includin8 fraud
and non-compliance wlth laws and regulations, was as follows:
we Identified the laws and regulations applicable to the group through discussions Wlth management, and from
our commercial knowledge and experience of the sector,.
• we focused on specific laws and regulatSons which we considered may have a direct material effect on the
account5 or the operation5 of the 8roup, includin8 the Charities Acl 2011;
we a55es5ed the extent ol compliance with the laws and re8ulations Identified above through rnakin8 enquiries 01
management and inspectin8 correspondence; and
• identified laws and regulations were communicated within the audlt team and the team remalned alert to
instances of non-compliance throu8hout the audit.
We assessed the susceptlbility of the charivs accounts to material misstatement, including obtaining an understanding of
how fraud might occur, by:
making enquiries of management a5 to where they considered there wa5 Susceptibility to fr¥ud, their knowledge
of actual, suspected and alleged fraud,. and
conslderin8 the internal controls in place to miti8ate risks of fraud and non.complSance with laws and
re8ulations.
To addre55 the risk of fraud through management bias alld override of controls. we:
• performed analytical procedures to identify any unusual or unexpected relatlonships,.
• tested journal entrie5 to identify unusual transactiori5,'
• a55essed whether judgement5 and assumptions made in determining the accounting estimates set out in the
accountin8 policies were indicative of potential bias,. and
• investl8ated the rationale behind si8niflcant or unusual transactlons.
In response to the risk of irregularlties and non-compliance with laws and regulations, we designed procedures which
Sncluded, but were not limited to..
agreeing financial statement disclosures to underlying supporting documentatlon.
reading minutes of meetings of those charged with governance,. and
enquirin8 of management as to actual and potential litigation and claim5.
Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those
leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the
more that compliance with a law or regulation is removed from the events and transactions reflected in the financial
Statements, as we will be less likely to become aware of instances of non.compliance. The risk Is also greater regardin8
irregularities occurring dLte to fraud rather than error, as fraud involves intentional concealment. forgery, collusion,
omission or misrepresentation.

PrSor year adjustments
The prlor year adjustment has been Included to remove the share of an associate's net assets which the group is
not in fact entitled to. The charitable company 15 one of three members of Radiology and Oncolo8y Con8fess
I"ROC"l. upon review the Tru5tee5 consider that it doe5 not show a true and fair view of the charitable group to
Include the share of the associaie's assets. The articles of ROC preclude the distribution of assets to members on
dissolution and no effective control exists, therefore the charltable group has no beneficial interest. The impact of
the adjustment on the con501idated Statement of financial activities was to reduce other income in the year to 31
December 2022 by £59,834. The impact on the consolidated balance sheet was to reduce restricted funds brought
forward by £111.575, reduce restricted fund5 a5 at 31 December 2022 by £171,409 and reduce fixed asset
investments at 31 December 2022 by £171,409. There was no impact to the charitable company balance sheet a5
at 31 Decernber 2022.
There has also been a prior year adjustment to reallocate £274,327 of membership subscriptions income from
donations Income to charitable activities income as this is a more appropriate allocation and reflects the nature of
the funding.
