What if there was an exact replica of your internal physiology out there in the cloud, connected to the physiology of million
others? Big data now allow researchers to simulate our blood flow accurately.

As part of the Beyond Imaging project, Cellule have worked with Lucy Hardcastle studio and King’s College London to develop an interactive installation enacting the unseen flow of the heart: Kalostasis, that premiered at the London Design Festival at the V&A museum.

“The permanent
motion of blood
keeps us alive.”

The permanent motion of blood keeps us alive. Each day, our heart beats around 100,000 times and pumps about 2,000 litres of blood. The aorta, the largest artery in the body, is responsible for transporting blood to each and every cell.
Researchers at King’s College London are using MRI to visualise blood flow in 3D and accurately analyse it’s behavior in people with aortic stenosis, a condition which causes a narrowing of the aorta.

“Kalostasis is an interactive installation using 3D data from MRI Imaging.”

Kalostatis is an interactive installation enacting
the unseen flow of the heart. The installation is simulating in 360° the beauty and complexity of the constant flow and motion that keeps us alive, its various extremes and our body’s ability to attain a state of balance, an equilibrium key to our health.

The data has been translated from research into digital simulation in 3D of various flow conditions, and the extremes responses that could be found with big data research on several patients.

The concept of equilibrium within the heart flow can be found throughout nature, raising questions about the dynamic rhythms and flows that rules our world.

“Showing us heart flow turbulence with real time graphics and sensor tracking.”

With Kalostastis, we wanted to showcase in a large scale experience the connection between the micro and macro: audiences can literally step inside a human heart. It shows us the powerful and constant rhythm of the heart flow, using real-time rendered graphics, projection mapping and sensor tracking; and this based on the latest advancement in medical imagery.

The various extremes are linked to the audience presence, causing turbulence that have been witnessed in various anatomies. When viewers leave the structure, the simulation will gradually return to its neutral state, referencing the power and stamina of the heart.

Beyond Imaging is guided by the research of Dr. Pablo Lamata and his team at the School of Biomedical Engineering & Imaging Sciences at King’s College London. Their team is developing a new digital approach to healthcare creating a digital twin of the heart, it’s mechanics and physiology.

In partnership with ECHO charity, and the British Heart Foundation, this collaboration represents an innovative opportunity to work alongside scientific
institutions to challenge how we communicate, design and represent data that impacts our lives.
