Introduction

The 4th Symposium on Intelligent Data Science for Radiological Imaging (iDSRI) between Universiti Malaya and Kyushu University was successfully held on the March 7, 2023 at the Department of Biomedical Imaging, Faculty of Medicine, Universiti Malaya, Malaysia. The meeting was co-host by the Medical Physics Division of the Malaysian Institute of Physics and the Department of Biomedical Imaging, Universiti Malaya. The aim of this symposium is to enhance research and teaching collaboration between the two universities in medical physics.

Brief history

The symposium was a result of a long standing collaboration between the two universities, starting with the signing of the memorandum of understanding between Universiti Malaya and Kyushu University. Under this collaboration, we discussed student exchange programme, short-term visit and attachment.

This led to the first visit by Professor Arimura and his team in March 13-14, 2017 and subsequently in December 13 – 14, 2018. Since then, we had started a research collaboration on radiomics research in approach to the identification of EGFR mutations among patients with NSCLC and published a paper. However, due to the COVID-19 pandemic, the physical visits were halted for a couple of years. Then in March 2021, the first iDSRI was held to continue the collaborative relationship between the two universities in the new paradigm. This was followed by the subsequent iDSRI, held twice a year, with the two universities hosting it alternatively. Table 1 – 3 shows the list of presentations and speakers for the first three iDSRI held online over Zoom and Google Meet platforms. The presentations covered various disease domain, medical imaging modalities, from radiomics, artificial intelligence to radiological science and dosimetry research.

In March 2023, Professor Arimura led a 3-person team for the third visit to Malaysia. During this visit, the 4^th iDSRI (Table 4) was held as a hybrid meeting at the Universiti Malaya. Seven speakers were invited, they were Professor Dr Hidetaka Arimura, Assistant Professor Dr Masatoshi Kondo, and Mr Takumi Kodama from Kyushu University and Emeritus Professor Dr Kwan Hoong Ng, Dr Li Kuo Tan, Associate Professor Dr Mee Hoong See, and Associate Professor Dr Mohammad Nazri Md Shah from the Universiti Malaya. The symposium was chaired by Dr Jeannie Wong and Dr Tan. The symposium was well attended with close to 60 attendees, including online and physical attendees.

Emeritus Prof Ng closed the symposium quoting from ‘The Little Prince’ “As for the future, your task is not to foresee it, but to enable it.” – Saint-Exupery. The visitors from Kyushu Universiti were also presented with souvenir as a token of appreciation from the International Unit of the Faculty of Medicine (IUFOM), Universiti Malaya. The symposium ended with a group photo taken (Figure 1).

During the visit, Prof Arimura and his team also met the Deputy Vice Chancellor (Academic & International), Prof Yvonne Lim at her office at the UM chancellery. At the Faculty of Medicine, they also met with the deputy dean of student affairs, Associate Professor Dr Tengku Ahmad Shahrizal Tengku Dato’ Omar, and the deputy dean of postgraduate studies, Professor Dr Shahrul Bahyah kamaruzzaman.

In the UM-KU collaboration, we explored activities such as student exchange and short-term attachment.
