Martin Christian HemmsenUltrasound imaging is one of the most popular diagnostic methods -  it is a non-invasive and low cost technique.

However, there are certain limitations. In conventional ultrasound, the recording of images is sequential in one direction at the time. This limits how many images can be shown per second, which is especially problematic when three dimensional imaging is desired, as in scans of the heart.

At CFU we are researching extensively in the ultrasound technique of the future - synthetic aperture – which should make it possible to obtain a better resolution, contrast and depth penetration.

Other research projects concentrate on methods to improve image quality by reducing speckle - the result of the constructive and destructive coherent summation of ultrasound echoes - and through optimizing operator-dependent controls.
