Abstract

PROPELLER (periodically rotated overlapping parallel lines with enhanced reconstruction) is a new method of MRI data collection and reconstruction technique for reducing motion artifact. However, the minimum imaging time in PROPELLER is markedly longer than in conventional fast MRI. Through the current research of K-Space Undersampling algorithm based on PROPELLER technique, a proper undersampling method is conducted and then proved by simulation. The new data collection method can shorten the PROPELLER time without causing more image artifacts, which improves the value of PROPELLER technique.
