Improving cardiac ultrasound in difficult-to-image patients
Despite constant improvements within the field of medical ultrasound, there are still a considerable number of difficult-to-image patient. Echocardiograms (heart images) taken from these patients do not have the quality that is needed for correct diagnosis. Therefore it is important to further improve the quality of echocardiograms.
Could your local doctor diagnose heart disease using a handheld ultrasound device?
Many potential heart patients that are referred to specialists, turn out not to need specialist care. If general practitioners (GPs) could use handheld ultrasound devices with built-in diagnostic tools, could this improve patient outcome and reduce cost for the health services?
DeepEcho: Machine learning for improved echocardiography
Increased availability of ultrasound devices is great news, but it also triggers a range of new challenges. At CIUS we believe modern machine learning methods, such as deep learning, can provide necessary solutions.
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.
Leaky heart valves – new method for quantification by ultrasound
A leaky heart valve, termed valvular regurgitation, causes some of the blood to flow in the wrong direction. It is one of two major features in valvular heart disease. The patient’s symptoms and prognosis depend heavily on the amount of leakage, which usually is determined…
Ultrasound automation simplifies detection of heart failure
Using an application developed at NTNU, helps physicians detect more patients with reduced heart function when assessing heart pump function in patients with suspected heart failure using ultrasound. Heart failure is a common disease among the elderly. Increased use of ultrasound of the heart or…
