Title: Imaging doses in radiotherapy: to know or neglect? 

Speaker: Prof Dr Tomas Kron

Tomas Kron was born and educated in Germany. After his PhD he migrated to Australia in 1989 where he commenced his career in radiotherapy physics. From 2001 to 2005 he moved to Canada where he worked at the London Regional Cancer Centre on the commissioning of one of the first tomotherapy units. In 2005, Tomas became principal research physicist at Peter MacCallum Cancer Centre in Melbourne, Australia where he now is Director of Physical Sciences. He holds academic appointments at Wollongong, RMIT and Melbourne Universities. Tomas has an interest in education of medical physicists, dosimetry of ionising radiation, image guidance and clinical trials demonstrated by 100 invited conference presentations and 330 papers in refereed journals. He has received many awards over the years including an Order of Australia Medal (2014), Fellowship of IOMP and IUPESM and Life Membership of the TransTasman Radiation Oncology Group (TROG) in 2020.


Radiotherapy is one of the main treatment modalities for cancer patient. It uses target doses in excess of 50 Gy to eradicate tumour cells. In the context of this high dose many people consider dose from imaging procedures that allow for treatment planning and delivery verification to be negligible, a position reflected in the lack of education about imaging dose optimisation for radiotherapy physicists and scant dose reduction methods available on commercial radiotherapy equipment. This presentation argues that this is a mistake not only because the framework of radiation protection urges us to justify and optimise all radiation doses. The number and complexity of imaging procedures is increasing and the volume of the patient irradiated and dose distribution in imaging is fundamentally different form the high dose region in therapy. As such a recently formed task group of ICRP is dealing with imaging dose in radiotherapy. This and experience of managing imaging dose in a large radiotherapy centre will be subject of the presentation.


Title: Radiation-induced Cancer Risk in Medical Imaging: To know or Neglect?  

Speaker: Prof Dr Anchali Krisanachinda

Anchali Krisanachinda graduated her B.Sc.(Hons) in Physics, M.Sc. (Radiation Physics) from University of London, UK, and Ph.D. (Medical Radiation Physics) from University of Health Science, North Chicago, Ill, USA. She was a Director of Medical Physics Graduate Program, Mahidol University, Bangkok, Thailand. She established Medical Imaging/Medical Physics, graduate programs, M.Sc. and Ph.D. at Chulalongkorn University and became Chairperson of both programs. She established Thai Medical Physicist Society (TMPS) in 2002, started the clinical training of medical physicists in 2007 and obtained Clinically Qualified Medical Physicist, CQMP, in radiation oncology, ROMP in 2009, DRMP in 2012 and NMMP in 2015. Then all 3 branches in medical physics clinical training were started at the same time using AMPLE (Advanced Medical Physics Learning Environment). Medical Physicists in South-East Asia join AMPLE sharing Thai Clinical Supervisors in ROMP and NMMP. The Ministry of Public Health of Thailand approved the medical physics national license in 2022, more than ten years after she requested. Hopefully, in 2023, there will be 300 Thai medical physicist with national license in medical physics. Continue Professional Development in medical physics will be later established. She has received many awards from her Faculty of Medicine and Chulalongkorn University, South-East Asian Federation of Organizations for Medical Physics (SEAFOMP), Asia-Oceania Federation of Organizations of Medical Physics (AFOMP), IOMP and IUPESM.


The risk model, the cancer sites, dose and dose rate effectiveness factor (DDREF) and mathematical models will be described presenting differences among the models. These models take into account parameters such as sex, age-at-exposure, attained age and time since exposure.

Medical Imaging

Patient dose from a chest X-rays is about 0.1 mSv, whole-body CT scan is about 10 mSv. The effective doses from diagnostic CT procedures may be associated with an increase in the possibility of fatal cancer of approximately 1 chance in 2000. This increase in the possibility of a fatal cancer from radiation can be compared to the natural incidence of fatal cancer in the U.S. population, about 1 chance in 5 (400 chances in 2000). In other words, for any one person the risk of radiation-induced cancer is much smaller than the natural risk of cancer. If the natural risk of a fatal cancer is combined to the estimated risk from a 10 mSv CT scan, the total risk may increase from 400 chances in 2000 to 401 chances in 2000. Nevertheless, this small increase in radiation-associated cancer risk for an individual can become a public health concern if large numbers of people undergo increased numbers of CT screening procedures of uncertain benefit.

Moderator: M. Mahesh (Scientific Committee Chair of the IOMP)
Speakers: Kevin W Eliceiri, Heather Whitney, Robert Finnegan

Title: Open Source Computational Imaging of Cellular Microenvironments

Speaker: Kevin W Eliceiri

Kevin Eliceiri is the RRF Walter H. Helmerich Professor of Medical Physics and Biomedical Engineering and Director of the Center for Quantitative Cell Imaging at the University of Wisconsin-Madison. He is also an investigator in the Morgridge Institute for Research. In 2022 he was named a Open hardware Trailblazer by the Open Source Hardware Association and the Sloan Foundation. His research focus involves developing novel optical imaging methods for investigating cellular microenvironment changes in wound healing, and the development of software for multidimensional image analysis. His lab has been contributing lead developers to several open-source imaging software packages including FIJI, ImageJ and μManager. ImageJ was named by Nature as one of the top ten computer codes that changed science. His open hardware instrumentation efforts involve novel forms of polarization, light sheet, laser scanning and multiscale imaging.


A primary interest of the Eliceiri lab is in developing novel imaging techniques that examine the interaction between cells and their microenvironment in space and time. Much of this work has involved the development of multiphoton based and computational approaches to interrogate cells noninvasively deep into intact tissue over time to study metabolism, cell signaling and stromal interactions. This has been particularly useful in  studies of cell differentiation and cancer invasion and progression. A major element of this work is the construction of novel open source imaging hardware platforms including custom fluorescent lifetime, spectral imaging systems and multiphoton laser scanning systems. This work entailed new open hardware developments in laser, detection and acquisition technology. Much of our focus in hardware development is at the intersection of hardware and computation. Our past efforts have mainly focused on open source image analysis and visualization (ImageJ), on the computational side, and image acquisition  (Micro-Manager) and device management on the hardware side. We are lead developers of the open-source project ImageJ/FIJI and in 2020 we launched the NIH P41 funded “Center for Open Bioimage Analysis” (COBA) to develop and maintain the open-source software CellProfiler and ImageJ while making new deep learning tools and workflow solutions for bioimaging. In 2021 we became the lead development home for Micro-Manager and OpenScan for light microscopy acquisition. We have been leading efforts to build an open source imaging informatics toolkit for light microscopy that         spans the complete life cycle of imaging from acquisition, image analysis, data storage, and data dissemination. These tools have included support for novel imaging modalities such as light sheet microscopy, new metadata standards for sharing data and improved image analysis packages such as our  work on ImageJ. This work on open source imaging software has enabled novel biological imaging studies and is in use by thousands of labs around the world. We now realize that there is an outstanding, untapped opportunity to advance computational optics, including opportunities for image analysis at runtime, where image processing routines can be run during acquisition to yield new insights and outcomes on data that would not be possible post-acquisition.  We are combining our hardware accelerated approaches with our new algorithms to develop “smart” microscopes that can make decisions at runtime and use these decisions to determine where to focus in large tissue arrays.



Title: Open source tools from the Medical Imaging and Data Resource Center  

Speaker: Heather Whitney

Heather M. Whitney, PhD is a research assistant professor in the Department of Radiology at the University of Chicago. She conducts research in computer-aided diagnosis of breast and ovarian cancer, focusing on the modalities of dynamic contrast-enhanced magnetic resonance imaging and ultrasound. Her primary areas of interest are in artificial intelligence and radiomics across the imaging and classification pipeline, from medical image acquisition to performance evaluation and data harmonization. She also conducts research and collaborates in MIDRC, the Medical Imaging and Data Resource Center. Within MIDRC she works on methods of task-based distributions, interoperability between data enclaves, and monitoring and studying the diversity and representativeness of the MIDRC data commons to foster research in AI and health disparities.


The Medical Imaging and Data Resource Center (MIDRC, is a multi-institutional collaborative initiative driven by the medical imaging community that was initiated in late summer 2020 to help combat the global COVID-19 health emergency and to accelerate the transfer of knowledge and innovation in the COVID-19 pandemic and beyond. MIDRC, funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) and hosted at the University of Chicago, is co-led by the American College of Radiology®, the Radiological Society of North America, and the AAPM. The aim of MIDRC is to foster machine learning innovation through data sharing for rapid and flexible collection, analysis, and dissemination of imaging and associated clinical data by providing researchers with unparalleled resources. In this talk, I will discuss the MIDRC open data commons and freely available resources developed by MIDRC investigators, including tools for building patient cohorts, building bias awareness in AI/ML development, and selecting performance metrics, as well as opportunities for contributing data.

Moderator: Prof Arun Chougule
Speaker: Dr. V. Subramani

Dr. V. Subramani, PhD is currently working as Assistant Professor of Radiation Oncology (Medical Physics) and Heading Medical Physics in the Department of Radiation Oncology at All India Institute of Medical Sciences, New Delhi. He is having more than 26 years of experience in in radiation oncology medical physics. He has publication of around 50 scientific research articles as author and co-authors in the field of radiation oncology. Also He has delivered around 70 invited guest lectures, chaired several scientific sessions and participated in the debates and panel discussions in the national and international professional organization’s annual and periodic scientific meetings for the last ten years in the field of advanced radiotherapy and medical physics. He is currently national secretary of Association of Medical Physicists of India (AMPI), IOMP Education and Training Committee member and also serves as Chief Editor of Asia-Oceania Federations of Organization for Medical Physics Newsletter.


The success of a cancer treatment depends on the ability to deliver the right treatment to right patient to a right dose at right time, which is an ultimate goal of precision medicine or precision oncology.  However, currently patients undergoing radiotherapy are treated using uniform dose constraints specific to the tumor and surrounding normal tissues. This population based one-size-fit-all approach results in significant adverse effects and suboptimal tumor control. Another concern with current approach is that two patients with nearly identical dose distributions can have substantially different acute and chronic morbidities leading to poor quality of life. Therefore, there is a need to develop an approach to overcome this limitation of current standard of care in oncology. Due to recent advances in biological and quantitive imaging, image processing analysis, computational power, cancer biology, biotechnology and genomics, there are tremendous growths and large amount of data is available for each individual patient.

The radiogenomics is an emerging field in precision radiation oncology. “Radiogenomics” has two meanings: “the study of genetic variation associated with response to radiation (Radiation Genomics) and “the correlation between cancer imaging features and gene expression (Imaging Genomics). Radiogenomics is a combination of both radiomics and genomics biomarkers, which is useful in guiding and personalizing treatment prescription and adaptation when changes occurring during the course of therapy. This is termed as Radiogenomics-Guided personalized radiation therapy. Both radiomics and radiogenomics biomarkers can be used to evaluate disease characteristics or correlate with relevant clinical outcome such as patient prognosis and treatment response. The common goal of discovering useful diagnostics, prognostics or predictive biomarkers to improve clinical decision making and ultimately enable the practice of precision and personalized medicine.

The presentation will address about the medical physics aspects of quantitative imaging biomarker, radiomics/radiogenomics model development, radiomics-guided radiotherapy using radiomics-target volume, radiomics-knowledge based treatment and also gnomically-guided radiotherapy including genomic-adjusted radiation dose and radiation sensitivity signature and models for personalized radiotherapy.

Main Objectives

  • To Believe in ourselves as women and face the challenges
  • To do the maximum energy in work and giving
  • To be always optimistic and believe of better future.

Middle Eastern women have a very limited opportunity when it comes to professional career and they are thought to be better off staying at home taking care of the household. Yes indeed, such fact existed in the old days. It has rooted from the very own families of the Arabs and continued in primary school where girls and boys studies separately. There is an opportunity then for women, but it was limited only to teaching and nursing profession. But gone are those days; opportunities have opened for women. Slowly, the colleges started admitting women in the so-called “men field” especially in the healthcare industry.

Eventually, I started work in healthcare as senior radiation physicist then became the Executive Director of Occupational Health and Safety Department where I direct various health and safety sections including the Radiation Safety Section which was later named as Medical Physics Section. Being the only Medical Physicist in Qatar then, I represented the country internationally and had the opportunity to work with various international organizations such as WHO, IAEA, UNEP to name a few, and has implemented some of their projects at the national level. It has always been my aspiration to further the advancement of the medical physics profession locally and regionally. I established the Qatar Society of Medical Physics (QSMP) and co-founded the Middle East Federation of Medical Physics (MEFOMP) which I also became the President in 2018-2021.

Title: Wearing more than one hat – is this the new fashion trend for women in medical physics? 
Speaker: Iuliana Toma-Dasu, PhD

Medical Radiation Physics Division, Stockholm University and Karolinska Institutet, Cancer Center Karolinska, 171 76 Stockholm

Iuliana Toma-Dasu is Professor in Medical Radiation Physics and the Head of the Medical Radiation Physics division at the Department of Physics, Stockholm University, affiliated to the Department of Oncology and Pathology at Karolinska Institutet in Stockholm, Sweden, and the Editor in Chief of Physica Medica – European Journal of Medical Physics.

Iuliana Toma-Dasu studied Medical Physics at Umeå University, Sweden, where she also became a certified medical physicist and received a Ph.D. degree. In parallel with her involvement in the educational program for the medical physicists run at Stockholm University, her main research interests focus on biologically optimised adaptive radiation therapy, including particle therapy, modelling the tumour microenvironment and the risks from radiotherapy.


Achieving gender equality has been one of the objectives of the medical physicists’ community in many European countries, as well as in many other places around the world. This objective has been partially reached, nowadays women in the medical physics being much less underrepresented than in other physics fields. Becoming a medical physicist and performing clinical duties is, therefore, possible for many women due to the various strategies developed and implemented at institutional, national or international levels within the professional associations under the IOMP umbrella. Reaching, however, higher positions in the hierarchy on either clinical or academic side in medical physics is still a considerable challenge for women compared to men. The question therefore is: how many hats should a woman wear, how many accolades should she receive, how many merits should she prove, to be regarded as successful in medical physics and accede to a leading position? This talk would attempt to answer some of these questions while highlighting the importance of successful women in medical physics to share their experience to inspire others and help the policy makers develop the most successful strategies to continue the work towards offering the same opportunities to all genders in the medical physics field.

He serves as an assessor for the Health Professions Council of South Africa and has acted as examiner and convenor for the Colleges of Medicine of South Africa. The IAEA has appointed Chris as an expert on numerous occasions, including on the implementation of the Basic Safety Series for medical professionals, on the prevention of accidents and incidents in radiotherapy, and most recently on a regional training course to train the trainers in radiation safety culture (hence the idea for this talk).

Chris was the recipient of the 2020 “International Day of Medical Physics” award for his services to medical physics in the FAMPO region.


Should have, would have, could have… many healthcare professionals may be familiar with that sinking feeling when a preventable incident has slipped through the safety net and reached the patient. The incorporation of safety culture in healthcare can help prevent many adverse incidents and events.

Safety culture can be defined as “the assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, protection and safety issues receive the attention warranted by their significance”. In fact, the Bonn Call for Action specifically proposed the strengthening of radiation safety culture as one of its ten main actions.

In 2021, the International Atomic Energy Agency published a booklet on safety culture traits and proposed ten traits – patterns of behaviour or thinking – that encourage the prioritization of safety.

The implementation of these traits is free, yet many systems fail to apply these characteristics effectively. In this talk a brief overview of the ten traits is given. The application of these will improve your institution’s safety culture.
