Subject

Medical signal processing

  1. Development of methods for acquisition and automated evaluation of spontaneous events in MRI: Spontaneous events are recordable in time series of MRI, which are automatically assessed by event detection and image segmentation approaches.
  2. Simultaneous acquisition of bioelectrical signals and MRI: Recording of bioelectrical signals during MRI necessitates post-processing and filtering of signal distortions due to MR gradient induced voltages. Moreover, suitable tools for the detection of small action potentials are required.
