Exploratory Soundscapes of Arterial Flow

Disturbances in flowing blood are clinically important, but not well understood. This is not helped by the fact that visualizations of blood flow, whether from medical imaging or computer simulations, can obscure as much as they enlighten. Our goal, unique to the study of blood flow, is to use sonification of the velocity data, and in particular the principles of dissonance and harmony, to discriminate deleterious from beneficial blood flow patterns, alone or in concert with traditional visualizations.


Dolores Steinman

Research Associate, University of Toronto

Dr. Dolores Steinman was trained as a Paediatrician and, upon relocating to Canada, obtained her PhD in Cell Biology. Currently she is a Research Associate in the Department of Mechanical Engineering at the University of Toronto and a volunteer Docent at the Art Gallery of Ontario. In her research she observes the rapport and the connection between medical imagery and its non-scientific counterparts. Her pursuit is driven by her keen interest in placing the ever increasingly technology-based medical research in the larger context of the humanities.

David Steinman

Professor, Mechanical Engineering, University of Toronto

Dr. David Steinman has spent almost two decades working to integrate computational fluid dynamics (CFD) and medical imaging, and the use of such “image-based CFD” and “virtual imaging” techniques to improve the understanding, diagnosis and treatment of vascular diseases. He is a full professor of Mechanical and Industrial Engineering and a core faculty member of the Institute of Biomaterials and Biomedical Engineering at the University of Toronto. He heads the Biomedical Simulation Laboratory. Dr. Steinman holds a Career Investigator award from the Heart & Stroke Foundation.

Diego Gallo

Biomedical Engineer, Politecnico di Torino

Diego Gallo is a PhD in Biomedical Engineering from the Politecnico di Torino, Turin, Italy. One of his research interest is the modeling of blood flow in arteries by means of computer simulations. Beyond this, he recently discovered the fascination of the contamination between science, music and art and the experimentation of a dynamic interchange between them.

Riccardo Castagna and Valentina Margaria

Green ON

Drs. Riccardo Castagna and Valentina Margaria are both scientists with a multidisciplinary background and a special interest in the intersection between technology, media, art and their effects on the community. They cooperated with the SMART COLLECTIVE – working on Nanoart projects and trying to make understandable what is not visible with naked eye. The evolution of this exploratory path has been the use of SONIFICATION, the data-dependent generation of sound, to communicate in a non VISUAL mode. In the last 2 years they have worked on SOUND DESIGN and GENERATIVE MUSIC foreseeing this approach as a powerful tool to convey complex information. They are co-founders of the GREEN ON project that wants to give voice to the environment, translating into music the interaction between plant and human.
