I participated in IUPESM World Congress 2025, which was held  from 29th September to 4th October in Adelaide, Australia. IUPESM stands for International Union for Physical and Engineering Sciences in Medicine, which is the union of IOMP (International Organization for Medical Physics) and IFMBE (International Federation of Medical and Biological Engineering). As IOMP is the federation of organisations for medical physics in each country, IUPESM congress can be understood as the world congress of medical physics and its related field of medical engineering. Most of the participants were from Asia or Oceania, probably because the congress was held in Australia this time.

I gave a presentation entitled ‘Proposal of pixel-wise MRI radiomics for grading prostate cancer’ on the first day. This was my first talk in an overseas congress in this field. I believe my academic message was well received by the audience, although the number of participants was not particularly high. By the way, some people may imagine that the world congress is a high-level meeting attended by top experts from each country. In reality, however, I felt that the quality of both the research itself and presentation skills were similar to those in the annual JSMP meetings. Since an academic congress is different from world athletic championships, it is not always beneficial to travel to a faraway country to attend the congress, spending much time and money.

In my opinion, one of the values of participating in this type of international congress is on knowing who are studying what issues in other countries. In my case, I got to know three excellent graduate students. B. S. Yahaya from Nigeria is ambitiously studying image analysis to diagnose hepatocellular carcinoma, based on deep understanding of the disease. R. Brown from Australia is analysing technical issues related to generating Consensus Segmentation by STAPLE method, and delivered a highly skilled presentation. C. White, a dignified Australian, asked highly insightful questions, so that I initially mistook him for a famous professor. Another value of attending the congress is that foreign researchers become aware of our studies and names, increasing the future possibility of joint research and academic opportunities, although I am not sure if I succeeded in that regard for now.

During my free time, I explored the city of Adelaide, frightened (yes, frightened!) by flora et fauna ignotae, and observed the Indian Ocean (or Southern Ocean) and the Southern Cross. I cannot show you pictures of them because no camera or phone (and not even a watch) was with me during the journey to the South, unfortunately.
