In September 2025, the international ultrasonics community came together in Utrecht for the 62nd IEEE International Ultrasonics Symposium (IUS). As the flagship congress of the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society (IEEE UFFC-S), IUS creates a platform for scientific exchange, bringing together researchers, industry and students to share knowledge, present new research and explore the future of ultrasonics.
From 15 to 18 September, participants from across the world gathered in Utrecht, a city with a longstanding connection to the field. It was here that Doppler ultrasound was first demonstrated experimentally, making Utrecht a meaningful setting for a congress focused on advancing ultrasound technologies and their applications.
IEEE UFFC-S has a partnership with Conference Catalysts as its Professional Congress Organiser. As Conference Catalysts is based in the United States, Congress by design was appointed as the local PCO. Its role was to provide on-the-ground expertise and act as the link between the international organising team and local venues, suppliers and stakeholders. Working closely with Conference Catalysts, Congress by design coordinated hotel management, venue operations, catering, audiovisual production, exhibition services and the social programme.
The programme combined technical sessions, plenary presentations, short courses and student activities with community initiatives such as Women in Engineering and the Dutch Ultrasound Ecosystem Day. Alongside the scientific programme, an exhibition featuring 52 international companies strengthened the connection between academia and industry.
Sustainability and accessibility also played an important role in the congress design. Utrecht’s central location enabled participants to travel easily by public transport, while the compact city centre made it easy to move between activities on foot. For the conference dinner, participants travelled together by climate-neutral train, reducing transport movements while creating a shared experience that reinforced the sense of community throughout the event. A dedicated team of volunteers provided on-site support, helping attendees navigate the event and ensuring a welcoming experience for participants from around the world.
IUS 2025 brought together the international ultrasonics community for four days of scientific exchange, collaboration and innovation. Researchers, industry professionals, students and sponsors connected through a programme that combined high-quality scientific content with valuable opportunities for networking and knowledge exchange.
Close collaboration between Conference Catalysts, Congress by design, the organising committee, suppliers and volunteers ensured the symposium ran smoothly. By combining international expertise with local knowledge, the project team created an environment in which participants could focus on sharing knowledge and advancing the field of ultrasonics.
The symposium further strengthened Utrecht’s position as a host city for international scientific conferences and provided a strong foundation for the continued development of the IEEE IUS community, with future editions taking place in Raleigh, Singapore and Dublin.
