Measuring the heart’s blood flow behaviour in 3D

An artificial ventricle – imaged alone on the ultrasound scanner – was made with a circulation system to simulate blood flowing in a heart chamber.

Given that cardiovascular related diseases are the most probable cause of death globally, according to WHO, we believe that more information regarding blood behaviour can help the doctors make better diagnosis at an earlier stage. But how can you measure these properties inside the heart, behind the ribs, under the skin, without moving the patients from their bed?

Blood flow secrets in small hearts

Using a new ultrasound technique, we have been able to visualize and measure how efficiently blood flows through the heart chambers in young children with congenital heart disease. We studied 37 children aged two weeks to 10 years, and among the 26 children, which had congenital heart disease, we found less efficient hearts, meaning they use more energy than a normal heart.

Blogger: Marcus Wild, PhD-candidate, Centre for Innovative Ultrasound Solutions (CIUS) and the University College of Southeast Norway. Within the maritime industry, ships use SONAR (Sound Navigation and Ranging) systems in order to make maps of the seabed. The problem with SONARs, is that they have a tendency to overheat. Our…

Breast cancer – and the pursuit of Super survivors

Vevsbiter fra brystkreftsvulster.

Bloger: Maria Ryssdal Kraby, PhD-Candidate, Department of Clinical and Molecular Medicine Breast cancer survival is high. However, many cancer survivors experience long-term side effects from treatment which impact their quality of life. For this reason, the Breast Cancer Subtypes Project studies a group of women we call Super survivors. They are…
