Speaker: Wille Häger
Wille Häger is a PhD student at the Department of Physics, Stockholm University, and Department of Oncology and Pathology, Karolinska Institute, in Stockholm, Sweden, under the supervision of Prof. Iuliana Toma-Dasu and Dr. Marta Lazzeroni. His PhD project is focused on models and computational tools for simulating the tumour invasion of high-grade gliomas and the potential implications for radiotherapy.
High-grade gliomas (HGGs) are notoriously invasive of normal tissue, and to this day prognosis remains poor. The main issue in treating HGGs appears to be determining the extent of the tumour invasion, as regions of considerable clonogenic cell populations are not detectable using conventional diagnostic imaging methods. This presentation will discuss the use of modelling to simulate the HGG growth and its invasion of brain matter, how well the simulated invasion agrees with the conventional clinical target volume (CTV) delineation, and the future prospects of model assisted CTV delineation and probabilistic treatment planning.

Speaker: Prof. Xie George Xu, University of Science and Technology of China (Hefei, China)
Prof. Xie George Xu is professor and director of the Institute of Nuclear Medical Physics, University of Science and Technology of China (Hefei, China). Before relocating to China recently, he was the Edward E. Hood Endowed Chair Professor of Engineering at Rensselaer Polytechnic Institute (Troy, New York, USA). He received a Ph. D. in Nuclear Engineering (health/medical physics focus) from Texas A&M University (College Station, Texas, USA) in 1994. Since 1995, Prof. Xu has mentored nearly 100 Ph.D and M.S. students in the U.S. and China. His research has focused on “radiation dosimetry” for radiation protection, medical imaging, and radiotherapy applications, with continuous funding by governmental agencies and private sector industry. His publication list includes 2 books, 200 peer-reviewed papers/chapters, 400 abstracts, and 140 invited talks. Widely known for his work on “computational phantoms” and “advanced Monte Carlo simulations”, Prof. Xu is a fellow of American Nuclear Society (ANS), Health Physics Society (HPS), American Association of Physicists in Medicine (AAPM), and American Institute for Medical and Biological Engineering (AIMBE), as well as a council member of the National Council on Radiation Protection and Measurement (NCRP) and a past president of the Council on Ionizing Radiation Measurements and Standards (CIRMS). He has been on the editorial board of Medical Physics and Physics in Medicine & Biology for 20 years. Prof. Xu and his team have developed a number of commercial software tools including VirtualDose (a CT and IR patient dose reporting software), ARCHER (a GPU-based Monte Carlo dose computing software for treatment planning and dose QA verification), and DeepViewer (an image segmentation and registration software tool). Prof. Xu has received numerous professional recognitions including, recently, CIRMS Randal S. Caswell Award for Distinguished Achievements (2015), HPS Distinguished Scientific Achievement Award (2018), ANS Arthur Holly Compton Award in Education (2020), ANS Rockwell Lifetime Achievement Award in Radiation Protection and Shielding (2020), and AAPM Edith H. Quimby Award for Lifetime Achievement in Medical Physics (2020).
Estimation of organ doses in medical physics depends on computational phantoms and Monte Carlo calculations ─ two tools that have seen major advancement recently. Phantoms have evolved from the 1st-generation stylized phantoms to 2nd-generation voxel phantoms, and to 3rd-generation boundary representative (BREP) phantoms. Aided with the latest deep-learning image segmentation tools, patient-specific phantoms can be created consisting of organ outlines ready for Monte Carlo calculations. And GPU-based Monte Carlo codes can reduce dose computing time from hours to less than one minute. This presentation will cover: (1) Historical review of computational phantoms and Monte Carlo codes, (2) Development of patient-specific phantoms using an automatic multi-organ segmentation tool, DeepViewer, that is based on neural convolutional network (called U-Net) , (3) Development of rapid Monte Carlo dose calculation code, Archer, that is based on nVidia GPU co-processors and virtual-source-modeling of medical accelerators. Examples in medical imaging dose (CT, PET/CT) and radiation treatment will be discussed.

Speaker: Suzy Lydiard, ACRF ImageX Institute, University of Sydney
Suzy Lydiard is a part-time PhD student at the ACRF ImageX Institute, University of Sydney, supervised by Prof. Paul Keall. Her PhD is investigating cardiac radioablation for atrial fibrillation, a new and developing non-invasive treatment alternative for the most common sustained cardiac arrhythmia. Her work is specifically evaluating the feasibility of an MRI-guided treatment on an MRI-Linac using non-invasive target tracking and MLC tracking. Suzy is also working as a clinical Radiation Oncology Medical Physicist at the Kathleen Kilgour Centre, New Zealand.
Cardiac radioablation has rapidly grabbed the attention of both clinicians and academics after stellar initial clinical results. Cardiac radioablation has the potential to advance and expand the clinical care available to those suffering from certain cardiac arrhythmias and is already being implemented within clinical trials globally. There are exciting and abundant opportunities for medical physicists and academics to help progress cardiac radioablation technologies and advance cardiac radioablation knowledge in order to make this treatment mainstream and accessible to those patients in need. This presentation will describe the clinical drivers for cardiac radioablation, discuss the challenges cardiac radioablation brings to radiotherapy, summarize the technology approaches currently utilized in clinical cardiac radioablation treatments, and identify potential research and development opportunities.

Speaker: John Shakeshaft, Site-Senior Physicist ICON Cancer Centre, Gold Coast, Queensland, Australia
John Shakeshaft currently works as the site-senior physicist at Gold Coast University Hospital within the ICON Cancer Care network. He has previously worked with both small and large radiation oncology departments across Australia and the UK (where he trained). He is the current chair of the Australasian College of Physical Scientists & Engineers in Medicine (ACPSEM) Radiation Oncology Specialist Group.
Recently he has also been the trial physicist for the Trans-Tasman Radiation Oncology Group (TROG) Cancer Research Stereotactic Radiosurgery (SRS) OUTRUN trial and chaired the technical working group developing guidelines for future TROG SRS trials.
Traditionally in Radiation Oncology margins are added to the clinical target volume (CTV) to allow for geometrical uncertainties in the planning and treatment. However, in stereotactic radiosurgery (SRS) some practitioners, particularly those treating with a Gamma Knife®, have not added margins to the CTV to form a planning target volume (PTV). This inconsistent approach to handling CTV-PTV between centres providing an SRS service, for example in a clinical trial, difficult.
The talk will consider:
– Geometrical uncertainties in SRS including the magnitude of the different contributing factors
– How different treatment modalities differ and the potential effect on margin requirements (for example achievable steepness of dose gradients)
– The effect of imaging for treatment position verification on modern treatment systems
– The ICRU91 approach for clinical trials
– Clinical evidence for the use of CTV-PTV margins in SRS

Physicists make quantitative measurements to determine therapeutic and diagnostic equipment safety and performance. Measurement uncertainty can influence acceptability decisions. Inappropriate equipment acceptance might result in hazardous operation. Improper rejection could be hazardous to patients if alternative equipment is not available in a timely manner.
This presentation reviews basic concepts and nomenclature for measuring instrument calibration and measurement uncertainty applicable to all areas of medical physics. A brief outline of the differences between manufacturers’ and medical physicists’ processes will be presented using fluoroscopic beam measurements as an example. It concludes with some clinical implications of acceptability.
