One probe, two frequencies – numerical optimization of dual-frequency transducers
At the heart of any ultrasound system, lies the transducer. The transducer is used for applications ranging from creating images of foetuses and disintegrating kidney stones (lithotripsy), to detecting cracks in gas pipes. Without it, the world at large would be a different place. See…
Ultrasound – a cross-sector solution
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…
Improvements in ultrasound transducer design and manufacturing
All ultrasound technologies in health care, maritime, and oil & gas make use ultrasonic transducers. For this reason, transducer design is a key research task of the Centre for Innovative Ultrasound Solutions (CIUS). Ultrasonic transducers are devices that convert electrical signals into mechanical vibrations and…
Exploiting nonlinear distortion to switch from black and white to colour in underwater acoustic imaging
When ultrasound propagates through water nonlinear effects come into play and distort the signal originally transmitted (Figure 1). The effect of this distortion can be seen as a transfer of energy around what is called “harmonic frequencies”. For example if the signal originally transmitted has…
CIUS fall conference day 2016
The second CIUS full-day conference held on 23 November 2016 in Trondheim, attracted near 80 participants representing CIUS researchers, partners, collaborators and international speakers. The day had a varied programme and ample opportunity for networking across work packages, institutions, and fields of speciality. CIUS director…
Planning the direction for CIUS
45 people from both academia and the industry were present at the first meeting discussing the direction for half the different work packages at NTNUs new centre CIUS, a Centre for Innovative Ultrasound Solutions for health care, maritime, and oil & gas. – At this…
