Title:
MAGNETIC RESONANCE IMAGING DEVICE AND RADIAL SAMPLING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/137606
Kind Code:
A1
Abstract:
A radial sampling method in which an FSE sequence is used in order for the contrast of effective TE echo data to be reflected more clearly in the image contrast without the imaging time being extended, and for an image having a contrast closer to the contrast expected from designating an effective TE, wherein the method is characterized in that the measurement sequence of the echo data in at least one blade is different from the measurement sequence of the echo data in another blade. More specifically, the measurement sequence of the echo data in one blade is inverted in the phase encoding direction of the blade with respect to the blade center or the echo data of the effective TE relative to the measurement sequence of the echo data in the other blade.
