Welcome to Center for Fast Ultrasound Imaging (CFU)
At CFU, we research in advanced digital ultrasound systems for anatomic imaging and flow imaging.
On this website, you will find information on all current research projects, our facilities, the people involved, and publications since the center was established in 1998.
CFU cooperates closely with BK Medical and Copenhagen University Hospital and 11 PhD students are currently affiliated with the center.

Synthetic Aperture Sequential Beamforming applied to medical imaging
Synthetic Aperture Sequential Beamforming (SASB) is applied to medical ultrasound imaging using a multi element convex array transducer.
The main motivation for SASB is to apply synthetic aperture techniques without the need for storing RF-data for a number of elements and hereby devise a system with a reduced system complexity. Using a 192 element, 3.5 MHz, λ-pitch transducer, it is demonstrated using tissue-phantom and wire-phantom measurements, how the speckle size and the detail resolution is improved compared to conventional imaging.
Measured PSF at depths of 41 and 91 mm obtained using a water tank phantom. The figures (a+c) is made using DRF and (b+d) using SASB
