In response to Peking University's "Disciplinary Quality Year" initiative, and with the aim of deepening interdisciplinary integration under the “Medicine + X” framework and advancing collaboration and development in medical technology, the Institute of Medical Technology at Peking University Health Science Center (hereinafter referred to as “the Institute”) has actively engaged in external cooperation and carried out a variety of domestic and international exchange activities. From August 25 to August 29, at the invitation of the Department of Health Technology and Informatics of the Faculty of Health and Social Sciences at The Hong Kong Polytechnic University, Researcher Xie Zhaoheng, Mr. Tang Zeqing from the Teaching Office, and eight undergraduate students from the Institute participated in an academic exchange at The Hong Kong Polytechnic University and its affiliated hospitals.

On the morning of August 26, faculty and students from both institutions held a thematic seminar on exchange and collaboration. Representatives from The Hong Kong Polytechnic University (PolyU) included Associate Dean of the Faculty of Health and Social Sciences Dr. Choi King, Professor Ip To-ping, Head of the Department of Health Technology and Informatics (HTI), Associate Head Professor Leung Hang-mei, Associate Professors Law Ka-wai and Wong Chin-ling, as well as Assistant Professors Lam Leung-ting and Lai Tin. The two sides engaged in in-depth discussions on key topics such as the training objectives, teaching systems, career development paths, and student recruitment and employment in the field of medical technology at both institutions. Multiple areas of consensus were reached regarding future mutual visits and collaborative exchanges. After the seminar, faculty and students from the Institute of Medical Technology visited PolyU’s teaching and research laboratories in medical imaging, radiotherapy, and clinical laboratory sciences. They also toured the university campus, where Assistant Professor Lai Tin introduced the history and general overview of The Hong Kong Polytechnic University.

Introduction to the Campus and Laboratory Tour of the Hong Kong Polytechnic

Students were divided into two groups based on their majors—Medical Imaging and Laboratory Medicine—for the visit and internship activities. On the afternoon of the 26th, the Imaging group participated in an ultrasound-related practical session led by Prof. Michael. Through Prof. Michael’s theoretical explanations and their own hands-on practice, the students gained an understanding of ultrasound principles, equipment operation, and the use and procedures of contrast agents. Meanwhile, the Laboratory group, under the guidance of Dr. C.L. Huang, visited Queen Elizabeth Hospital, where they learned about the hospital’s advanced medical equipment and diagnostic workflows. Senior students Ms. Adenike Adesanya and Mr. Jiahong Sun gave in-depth presentations on drug resistance and mutation detection methods in chronic myeloid leukemia, as well as the fundamental principles of whole-genome sequencing for genetic disease analysis.

On the 27th, the Medical Imaging group engaged in an X-ray–focused practical session under the guidance of Prof. Dave. Through two core experiments—measuring the half-value layer (HVL) of X-rays and capturing X-ray images—Prof. Dave helped students grasp the fundamental principles of X-ray generation and transmission. The session also familiarized students with key considerations in image acquisition and introduced them to basic techniques in interpreting X-ray images. Meanwhile, the Laboratory Medicine group, guided by Dr. Kent Wong, conducted experiments involving whole-genome amplification and gel electrophoresis. Following the lab session, Dr. Lealem Bimerew and Mr. Zhiwei Jiang delivered detailed lectures on the mechanisms of COVID-19–induced immunothrombosis and the fundamentals of single-cell data analysis. Students were then given hands-on training in droplet digital PCR (ddPCR) techniques, including practical workflow execution and data interpretation.

On the 28th, the Medical Imaging group visited the Radiotherapy Planning Laboratory for a hands-on learning session. Vincent Leung provided an overview of radiotherapy practices in both public and private hospitals in Hong Kong. The session then focused on organ delineation in CT images and the design of radiotherapy treatment plans, allowing students to familiarize themselves with the identification of lesions and normal tissues. Through this process, students gained a preliminary understanding of the fundamental principles and methodologies involved in radiotherapy planning. Later, the group visited the Radiotherapy Department at the Eastern District Yuet Mei Hospital, where they observed the daily operations of radiotherapy professionals. Students had the opportunity to explore a variety of radiotherapy planning techniques and witnessed the clinical application of linear accelerators in treatment.

On the 28th, the Medical Imaging group visited the Radiotherapy Planning Laboratory for an immersive practical session. Vincent Leung delivered an overview of radiotherapy practices in both public and private hospitals across Hong Kong. The session then shifted focus to the delineation of organs in CT images and the design of radiotherapy treatment plans, providing students with the opportunity to familiarize themselves with the identification of lesions and normal tissues. This hands-on experience allowed students to develop an initial understanding of the core principles and methodologies in radiotherapy planning. Subsequently, the group toured the Radiotherapy Department at the Eastern District Yuet Mei Hospital, where they observed the daily activities of radiotherapy professionals. Students gained insight into various radiotherapy planning techniques and had the chance to witness the clinical application of linear accelerators in treatment.

This exchange and visit not only broadened the students' perspectives, allowing them to experience the diverse teaching methods of different universities, but also provided them with a deeper understanding of the campus culture and educational philosophy at PolyU. The experience served as a valuable opportunity for personal and professional growth. Furthermore, faculty members from both institutions exchanged views on the development of their respective departments, sharing insights on exemplary teaching practices and research experiences. Both sides look forward to further collaboration between the two departments, aiming to contribute significantly to the cultivation of outstanding talent in the medical field and the innovation of medical technologies.
