Team: Scott Hoge, Bob Kraft

Goals: Further integrate algorithms from the Fast Imaging Library (doc here: http://www.spl.harvard.edu/publications/item/view/1393) to enable interactive EPI measurements for perfusion, fMRI, and temperature monitoring using accelerated and efficient EPI-based MR acquisitions


Approach:

  • complete a mechanism to maintain the phase in our pMRI-UNFOLD-EPI-PROPELLER acquisition technique, which is required for both temperature change estimation and EPI distortion correction
  • incorporate real-time hooks into EPI sequence, to provide interactive acquisitions
  • start investigations into radial EPI

Other Notes:
