Research interests

I am interested in the application of deep Learning in MRI/MRSI. The acquisition of whole-brain MRSI data requires advanced acquisition techniques e.q. non-cartesian encoding or undersampling of kSpace, which in combination with multi-channel coils generates a large amount of data and yields prolonged reconstruction time. Prolonged acquisition time makes the MRSI/MRI methods vulnerable to the patient's motion, which decreases the quality of the measured data.

I believe that several challenges can be solved by applying the deep learning methods during the acquisition of raw data or in post-processing.
