Interests
Research
Dr. Altbach’s research group is focused on the development of novel magnetic resonance imaging (MRI) techniques for improving the diagnosis of disease. We develop novel acquisition and reconstruction strategies and we work closely with clinicians to translate them into the clinic. One of the major goals is to be able to derive parameters for the quantification of disease from data acquired within the time constraints of a clinical MRI examination. The idea is to complement the current qualitative-approach of clinical radiology with a quantitative or “parametric” approach. This should not only improve the accuracy in diagnosis but it should also allow radiologists to interpret data faster. One of the major goals is to develop acquisition and reconstructions strategies that can yield quantitative parameters for the characterization of disease.
