MR imaging in biomedicine

We are researching and developing new, faster and highly functional magnetic resonance methods that offer physicians greater support in their diagnosis and shorten medical examinations for patients.

Parallel imaging is a key technology in magnetic resonance (MR). By using several transmitters and receivers at the same time, this method accelerates the imaging process. To ensure that images are also of high quality, the image data must be reconstructed in an elaborate way. We are constantly refining our methods based on the latest technological developments in signal analysis.

Shorter imaging times open up completely new fields of application that previously took longer than patients would accept. One example is three-dimensional quantitative MRI.  Conventional image contrasts are based on variations in water content and other tissue-specific parameters. The brightness values shown on an image are determined by how these parameters are weighted in the imaging software. A comprehensive diagnosis usually requires several of these contrasts, which involves acquiring a sequence of discrete images. If the symptoms are clear, medical professionals know which contrasts will point to the cause. In other cases, standard parameter weighting is used; if anything out of the ordinary is detected, it may be necessary to arrange another examination.

Unlike conventional examination methods, quantitative MRI takes a holistic approach that requires only one examination. Rather than recording particular contrasts, this method records the underlying tissue-specific parameters. The benefit of this approach is that it allows physicians to use software during the diagnosis to select the contrast they need in order to determine the cause.
