Title: Spectral-Tagging Technique for Improving Resolution and Acquisition time of Dynamic Echo-Planar Imaging
Invention: The invention is a spectral-tagging method that allows for 3X faster speed of acquisition witn improved resolution of the targeted physiology. The invention improves upon echo-planar imaging by band-pass filtering different signals to reconstruct a specific spectral peak, resulting in high quality images without aliasing artifacts from multi-band echo-planar imaging signals.
Background: Echo-planar imaging is the most wildly used pulse sequence for dynamic magnetic resonance imaging. The drawback with this process is that conventional protocols result in artifacts, multi-band imaging is not feasible for in-plane parallel imaging, and simultaneous echo refocusing results in compromised spatial-resolution and accuracy when used with multi-band imaging. Therefore there is a need for improved echo-planar imaging spatial-temporal resolution for accurately capturing physiology.
