摘要

摘要

En 中文
This paper presents a fast spin echo (FSE) imaging method that employs circular sampling of k-space, The technique has been implemented on a 2 Tesla imaging system and validated on both phantoms and living animals, Experimental studies have shown that circular sampling can produce artifact-free FSE images without the need of phase correction, Although not fully explored, preliminary results also show that circular sampling may have advantages over the conventional rectilinear FSE in signal-to-noise ratio and imaging efficiency, A major disadvantage is the increased sensitivity to off-resonance effects, The authors expect that the FSE technique with circular sampling will find its applications in magnetic resonance microscopy, neuro-functional imaging, and real-time dynamic studies.
