Abstract: Ultrasound is a versatile, non-ionizing, and portable imaging modality that has emerged as a cornerstone technology for medical diagnostics and physiological monitoring in space missions. This presentation provides a top-level overview of contemporary ultrasound methods and their relevance to medical applications, with particular emphasis on the unique constraints and opportunities of space healthcare. In microgravity environments, ultrasound serves as a primary tool for real-time assessment of musculoskeletal, cardiovascular, abdominal, and ocular conditions, as well as for guided procedures and longitudinal health monitoring of crew members during long-duration missions. A central focus of the talk is the paradigm of software-defined ultrasound (SDU), in which signal generation, beamforming, data acquisition, and image reconstruction are largely implemented in software rather than fixed hardware. SDU enables unprecedented flexibility, rapid prototyping of novel imaging modes, and adaptation of ultrasound systems to mission-specific requirements—key advantages for space applications where mass, power, and reconfigurability are critical.
The presentation introduces ultrasound research platforms developed by us4us Ltd. that embody the SDU concept and enable the implementation of advanced ultrasound modalities. These platforms support full access to raw channel data and programmable transmit–receive chains, facilitating research in next-generation imaging techniques beyond conventional B-mode and Doppler methods.
Finally, experimental results from Vector Flow Imaging (VFI) studies conducted during parabolic flight campaigns are presented. These results demonstrate the feasibility of quantitative blood flow assessment under altered gravity conditions and highlight the potential of advanced ultrasound techniques for robust cardiovascular monitoring in space. Together, these findings underscore ultrasound’s expanding role in future human space exploration and autonomous medical care.
Author bio: Dr Marcin Lewandowski <marcin@us4us.eu>
Since receiving a master’s degree in physics followed by a PhD in Electronic Engineering (2009), Marcin Lewandowski has headed many R&D projects, product designs,
and medical device developments. He has authored numerous publications in scientific journals on the medical and industrial applications of ultrasound.
Over the course of 30+ years working in ultrasound, electronics and software development, Marcin has strived to apply his research expertise in projects with a strong potential for innovation and commercialisation.
Today, he balances work in research with his role as CEO at us4us Ltd., which produces original ultrasound solutions for research, biomedical and industrial applications. He has served as Principal Investigator for research projects funded by the European Space Agency (ESA), the National Science Centre (NCN), and the National Centre for Research and Development (NCBR).
He has published in journals including Neuroscience, Brain Research Bulletin, Social Neuroscience, and Brain-Computer Interfaces.
He is a member of the Cognitive Neuroscience and Neuropsychology Section of the Committee on Psychological Sciences of the Polish Academy of Sciences (PAN), the Polish Neuroscience Society (PTBUN), and the Psychonomic Society.
