Blood flow secrets in small hearts

Ultrasound images of trtralogy of fallot.

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.

Ultrasound – a cross-sector solution

Collage of speakers at CIUS Spring Conference 2017.

Cracks, unevenness, leakages, or speed and direction of liquid flows in vessels or pipes, hearts or pumps, are challenges faced by people in healthcare, oil & gas and the maritime sector. At the Centre for Innovative Ultrasound Solutions (CIUS), we work on improving ultrasound technology and usage to address these…

Interpreting ultrasound images with neural networks

The femoral nerve (yellow) and femoral artery (red).

Blogger: Erik Smistad, PostDoc at Centre for Innovative Ultrasound Solutions (CIUS)       Neural networks have recently achieved incredible results for recognising objects such as cats, coffee cups, cars and plants in photographs. These methods are already used by companies like Facebook and Google to identify faces, recognize voice…
