Summary of Research Activity: 

Dr. Altbach’s research group is focused on the development of novel magnetic resonance imaging (MRI) techniques for improving the diagnosis of disease. Working closely with clinicians her group develops novel acquisition and reconstruction strategies to improve the diagnosis of heart disease and cancer. One of the major goals is to be able to derive parameters for the classifications of small tumors from data acquired in a short period of time for patient comfort. The idea is to complement the current qualitative-approach of clinical radiology with a quantitative or “parametric” approach which should improve the accuracy in diagnosis and reduce the time that a patient has to spent in the magnet.
