Research at CFU

Research at CFU spans the development of algorithms and their implementation, development of equipment, pre-clinical trials and efficacy evaluation of the new techniques. Several major results have been obtained, published and patented.

To read more about the individual research areas, choose in the menu to the left.

Ongoing research projects include:

  • Synthetic Aperture Compound Imaging
  • 3D Vector Flow Imaging
  • Synthetic aperture flow imaging using a dual beam former approach
  • Non-linear SA Imaging
  • Micromachined integrated transducers for ultrasound imaging

One of our successes is a research scanner for SA imaging - RASMUS. The scanner can send out advanced coded fields and acquire data from all transducer channels in real time for clinical imaging. The system generates 5 GBytes of data per second, and this can be stored in the internal 16 GBytes memory for the system. This makes it possible to make clinical, real-time data acquisition and storing the data in a 32 processor Linux cluster for processing.

All developed methods have been investigated on data from human volunteers using this system, and the methods have been shown to function for clinical imaging.

A simulation package, Field II, for ultrasound imaging has also been developed at CFU and distributed on the web. The software is considered a standard for simulating ultrasound systems and is used by numerous research groups and market leading companies (Philips, Siemens, General Electric, Esaote, B-K Medical, Aloka, Vermon).

Engineers and researchers from the private industry are active collaborators suggesting specific topics for M.Sc. or Ph.D. projects and contributing with their experience and expertise in applied research and development as well as acting as external supervisors.
