Meet the researcher: Ellen Katrine Sagaas Røed
Ultrasound technology can be used to so much more than just medical images. At the Center for Innovation in Ultrasound (CIUS), we’re working together to find out how ultrasound can solve problems. One of our researchers is Ellen Katrine Sagaas Røed, PhD candidate at the University…
Reducing SONAR overheating
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 can have a tendency to overheat. Indeed, SONARs are composed of materials which exhibit energy loss, i.e., a…
Tormod Njølstad hired as Innovation Manager in Ultrasound at ISB
Tormod Njølstad (59) is hired as Innovation Manager in the Ultrasound group at ISB by September 2018.
With CIUS at IUS
Twenty-nine experts and researchers associated with CIUS participated at IUS, the IEEE International Ultrasound Symposium in Kobe, Japan, in October 2018. Not only the number of attendees, but also the number of presentations from CIUS was impressively high. The overall scientific contribution from the CIUS…
Making analog-to-digital converters for digital ultrasound probes
Making good digital ultrasound probes is extremely challenging because of the constrained amount of power that can be used. If significantly more than a couple of watts are consumed, the probe gets too hot to be allowed to touch your skin.

Potential improvement in sonar seabed mapping
Today, a significant part of the oceans remains coarsely mapped. Some specific areas like the continental shelves will require high-resolution surveys. This represents a very long and expensive task that will keep scientist busy for several decades. A way to reduce costs and time could be to improve the efficiency of current surveys. We are trying to do this by sending more signals in the water at the same time.
The Multi-beam echo sounder is recognized as one of the most efficient and reliable tool for seabed mapping. Applications range from regional mapping of the seabed for geological surveys to the inspection of man-made objects such as pipelines or ship wrecks.

Enhancing marine sonar and medical ultrasound imagery using wave coherence
CIUS researchers are investigating whether a property of ultrasonic waves known as coherence can be used to detect microcalcifications in human tissue for cancer screening. In marine sonar, it has already been used successfully for detecting and characterising objects and features on the seafloor. The…
Innovations in ultrasound – CIUS Fall Conference Day 2017
Innovation was the main topic at the Fall Conference Day for the Centre for Innovative Ultrasound Solutions (CIUS). Invited guest speakers, industry partners and CIUS researchers presented the latest, and coming, technology and applications within ultrasound. CIUS industry partners Aurotech Ultrasound AS opened the conference…
Reducing SONAR overheating
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 aim is to predict the temperature rise in the materials used in…
