Title: Separation and identification of water and fat mr image in mid-strength magnetic field reduced in t2/t2* weighting
Inventor: ZHANG WEIGUO
IPC: A61B5/055
Filed: 2002-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging (MRI) method for generating and identifying an MR image in which water and fat is separated from each other. SOLUTION: Image data are collected first and two echo images are obtained. The water and fat signals are orthogonal in the first echo image and they are parallel/antiparallel in the second echo image. By removing the nonuniformity of a background magnetic field, the images of the water and fat are separated from each other. The images of the water and fat are identified according to the difference in the frequencies of precession of the equinoxes.

Tapered parts 9a and 9b are formed in advance on the end parts 7 of the unvulcanized rubber sheet 6. The thickness of a lap part 8 made by piling up the both end parts 7 becomes approximately the same as the thickness of other sites. When this is covered with a shell bag and vulcanization molding is performed in a vulcanization oven, an amount of the unvulcanized rubber of the lap part 8 flowing in the width direction and in the peripheral direction is decreased. A positional shift of the wire 3 due to flow of the unvulcanized rubber hardly occurs. Turbulence of rotational transmission between a drive pulley and a driven pulley can be suppressed so that noises due to vibration of the transmission belt can be prevented.  <P>COPYRIGHT: (C)2004,JPO
